How many questions are on the Oklahoma written test?

The Oklahoma SOK written knowledge test covers road signs, traffic laws, and safe driving. You need to score at least 80% to pass. Road signs are included in the test — there is no separate signs test.

What topics are covered on the SOK knowledge test?

The test covers road signs and shapes, traffic signals, right-of-way rules, DUI and alcohol laws, school bus rules, speed limits, parking regulations, lane markings, and safe driving practices from the official Oklahoma Driver Manual (2025).

What is the passing score for the SOK written test?

The Oklahoma SOK written test has no officially published question count. Need 80% to pass. Road signs are included — there is no separate signs test.

What is the minimum age to get a Oklahoma learner's permit?

Oklahoma Learner Permit available at age 15 (with approved driver education) or 16 (without). Must hold permit for at least 180 days before taking the driving test. Intermediate License (T restriction) issued at age 16 (with driver education) or 16½ (without) — after holding permit 180+ days and presenting a Work Zone Safe certificate. T restriction removed after 6 months (with DE) or 1 year (without). Full unrestricted Class D License at age 18. Parent/guardian consent required for all applicants under 18.

Does Oklahoma have a hands-free cell phone law?

Oklahoma law prohibits writing, sending, or reading electronic communications while driving (Oklahoma law). Talking or dialing is not specifically prohibited but anything that distracts from driving is dangerous. ALL Learner Permit and Intermediate License holders are completely prohibited from using any wireless communication device while driving — except to report illegal activity or summon emergency help (Chapter 1–12).

⏱️

Following Distance & Time Rules

ON EXAM

3-sec rule

Three-Second Rule — allow at least 3 seconds between you and the car ahead. OR use 1 car length for every 10 mph of speed. Select a fixed object; the car ahead should pass it and you should count to 3 before reaching the same point (Chapter 8)

4 seconds

Bad weather or poor road conditions — increase your following count to 4 seconds (Chapter 8)

200 ft

Motorcycle following distance: allow at least a 3-second following distance so the motorcyclist has room to maneuver (Chapter 10)

Illegal (2015)

As of 2015, it is illegal to text while driving in Oklahoma. Commercial/transit drivers are also prohibited from hand-held phone calls while driving (Chapter 11)

🚦

Road signs are tested heavily. Know each sign's shape, color, and meaning. The real test often shows a sign description and asks what it means.

🔴

Sign Shapes — Each Shape Has One Meaning

ALWAYS TESTED

Shape	Meaning	Example
Octagon (8-sided)	STOP — always and only	Stop sign
Triangle (pointing down)	YIELD — give right of way	Yield sign
Diamond	WARNING — hazard ahead	Curve, pedestrian, deer
Pentagon (5-sided)	SCHOOL ZOKS	School crossing
Pennant (triangle right)	NO PASSING ZOKS	No-passing pennant
Round (circle)	RAILROAD CROSSING advance warning	RR crossing sign
Rectangle (vertical)	REGULATORY — rules you must follow	Speed limit, turn restrictions
Rectangle (horizontal)	GUIDE or INFORMATION	Street name, mile marker
X-shaped crossbuck	RAILROAD CROSSING — treat like yield	Railroad crossbuck

🎨

Sign Colors — Color Tells You the Category

ALWAYS TESTED

Color	Category	What It Means
Red	Regulatory — STOP / PROHIBIT	Stop, yield, do not enter, wrong way, no-turn circles
Yellow	WARNING	General hazard warnings — curves, hills, intersections, animals
Orange	WORK ZONE / CONSTRUCTION	Construction ahead, road crew, slow down and drive with care. Fines for speeding in a work zone are doubled in Oklahoma (Oklahoma Driver Manual)
Green	GUIDE / DIRECTIONAL	Highway exits, distances, direction, mile markers
Blue	SERVICES	Gas, food, lodging, hospital, rest area
Brown	RECREATION / CULTURAL	Parks, campgrounds, historical sites, scenic areas
White	REGULATORY	Speed limits, lane rules, turn restrictions
Fluorescent Yellow-Green	WARNING — pedestrian / school / bike	School zones, crosswalks, bike lanes
Fluorescent Pink	INCIDENT MANAGEMENT	Crash clean-up, debris removal, temporary traffic control

⚠️

Signs That Are Frequently Confused

TRICKY

No Passing Pennant vs. No U-Turn: The pennant (pointing right) = no passing. A circle with a slash over a U-turn arrow = no U-turn. Very different.

Crossbuck (RR) vs. Stop Sign: The crossbuck (white X) = yield/slow down and check. Only stop if a train is coming. The octagon = always stop.

Divided Highway Begins vs. Ends: Begins = two arrows pointing apart (median starts). Ends = two arrows merging together (median ends — expect two-way traffic).

Merge vs. Lane Ends: Merge = two roads joining (both cars adjust). Lane Ends = one lane disappears — that driver must yield and merge.

Red Circle with Slash: Always means that action is PROHIBITED. No left turn, no trucks, no bicycles — whatever is inside the circle is forbidden.

⭐

Right of way is the #1 failure topic on the SOK knowledge test. Master every scenario below — these questions will be on your exam.

⛽

The Core Right-of-Way Rules

MOST TESTED

Uncontrolled intersection — arrive at same time: Yield to the driver on your RIGHT. This is the most tested right-of-way rule.

Left turn at green light: You must always yield to oncoming traffic AND pedestrians — even with a green light. A green light is permission to go, not a guarantee of right of way.

Pedestrians in a crosswalk: Always yield. Stop and wait until the pedestrian has completely crossed — not just stepped back. This includes jaywalkers in many situations.

Blind pedestrian (white cane / guide dog): Absolute right of way — you must stop at least 15 feet from a blind person in the roadway or at an intersection. Stop outside the crosswalk, not in it (Chapter 5).

Four-way stop: First to arrive goes first. Simultaneous arrival = yield to the driver on your right. Straight traffic before turning traffic if both arrive at same time from opposite directions.

Emergency vehicles (lights + siren): Pull to the right edge of the road and stop. Clear intersections first — never stop IN an intersection.

Entering from driveway / private road: Always yield to all traffic on the public road — you have no right of way entering from private property.

Roundabout: Vehicles inside the roundabout always have right of way. Entering traffic must yield. When exiting, yield to pedestrians at the crosswalk.

Merging onto a highway: Traffic already on the highway has right of way. The merging vehicle must yield and find a safe gap.

Non-functioning traffic signal: Treat as an all-way stop. All drivers stop, yield, and take turns.

💡

Right-of-Way Scenarios That Trick People

TRICKY

Yellow light: It does NOT mean speed up. If you can stop safely, you must. Proceed only if stopping would be unsafe (you're too close to stop).

Already in intersection when light turns red: Complete the turn — you are committed. Other traffic must wait for you to clear.

Backing out of a driveway: The reversing vehicle always yields to street traffic. You have no right of way in reverse.

Blocking an intersection: Even with a green light, you may NOT enter an intersection unless you can get all the way through without blocking traffic. If caught in the intersection when the light changes to red, your vehicle is illegally blocking traffic (Chapter 6).

Right turn on red: Legal ONLY after a complete stop and yielding to ALL traffic and pedestrians. Rolling right on red is illegal.

Left on red: Permitted when turning from a one-way street onto another one-way street only — after a complete stop and yielding to all traffic and pedestrians. This is the only left-on-red allowed in Oklahoma (Chapter 4).

🚥

Traffic Signal Meanings

ALWAYS TESTED

Signal	What You Must Do
Solid GREEN	Proceed — but yield to traffic already in intersection
Solid YELLOW	Prepare to stop if safe; proceed only if stopping would be dangerous
Solid RED	Stop completely; may turn right on red after stop and yield (unless posted)
GREEN ARROW	Protected turn — oncoming traffic must stop. You may turn in the arrow's direction, but still yield to vehicles and pedestrians already in the intersection.
YELLOW ARROW	Protected turn is ending — prepare to yield or stop
Flashing YELLOW ARROW	Unprotected turn — you MAY turn but MUST yield to oncoming and pedestrians
Flashing RED	Treat exactly like a STOP sign — stop, yield, proceed when safe
Flashing YELLOW	Caution — slow down and proceed carefully. Do not need to stop.
RED + GREEN ARROW	Stop for through traffic; turn in direction of arrow only
Signal NOT working	Treat as ALL-WAY STOP — all traffic stops

🛣️

Lane Markings — Know Each One

ON EXAM

Broken yellow center line: Passing is permitted from your side when it is safe.

Solid yellow line on your side: No passing from your side of the road.

Double solid yellow: No passing in either direction.

White lines: Separate traffic going in the same direction. Broken = lane change ok. Solid = discouraged (but not always illegal).

Yellow lines: Separate traffic going in opposite directions.

Center left-turn lane (two-way turn lane): Use ONLY to prepare for and make a left turn. Never use as a travel or passing lane.

Yellow X over a lane: Lane is CLOSED — move to a lane with a green arrow immediately.

White stop line: Stop your front bumper at or behind this line at intersections and crosswalks.

↔️

Safe Lane Changing Procedure

STEP BY STEP

Check your mirrors — rearview and side mirror on the side you're moving to

Signal your intent — at least 100 feet before turning or changing lanes

Look over your shoulder — physically check the blind spot. Mirrors cannot see everything.

Change lanes gradually — smooth and controlled, not jerky

Cancel signal and adjust speed to match the lane's traffic flow

🚨

DUI questions appear on virtually every SOK knowledge test. Know the BAC levels, implied consent law, and penalties. Oklahoma uses "DUI" (Driving Under the Influence).

🍺

DUI Laws — The Numbers You Must Know

ALWAYS ON TEST

Situation	Consequence
BAC 0.08%+ — 1st DUI offense (21+)	Misdemeanor. Jail not less than 10 days, not more than 1 year. Fine of not more than $1,000. Service Oklahoma suspends license 30 days upon conviction. If BAC test failed at arrest: Implied Consent 180-day revocation (Chapter 12).
BAC 0.08%+ — 2nd offense within 10 years	Felony. Imprisonment 1 to 5 years. Fine of not more than $2,500. License revoked 1 year (if prior DUI within 10 yrs) (Chapter 12).
BAC 0.08%+ — 2nd felony offense	Felony. Imprisonment 1 to 7 years. Fine of not more than $5,000 (Chapter 12).
BAC 0.08%+ — 3rd or subsequent offense	Felony. Imprisonment 1 to 10 years. Fine of not more than $5,000. License revoked 2 years (if 2+ prior DUIs within 10 yrs) (Chapter 12).
BAC 0.05%–0.08% (any driver)	Relevant evidence of impairment. On conviction: fine $100–$500, up to 6 months in jail, or both (Chapter 12).
ANY measurable alcohol — driver under 21	Zero Tolerance. 1st offense: 6-month revocation, fine $100–$500. 2nd offense: 12-month revocation, fine $100–$1,000. BAC 0.08%+ = same adult DUI penalties (Chapter 12).
BAC test refusal (Implied Consent)	Automatic revocation of 180 days to 2 years depending on prior driving record — even if NOT convicted of DUI. Refusing cannot prevent losing your license (Chapter 12).
Court conviction suspension (separate from above)	Service Oklahoma ALSO suspends upon court conviction: 30 days (1st), 6 months (2nd), 1 year (3rd). Will NOT stack if Implied Consent revocation already imposed for same incident (Chapter 12).

💡

Critical DUI Facts to Remember

TESTED

Implied Consent: By driving on any Oklahoma public highway, you automatically consent to a chemical test (breath, blood, or urine). Refusing results in automatic revocation of 180 days to 2 years, depending on prior driving record — even if NOT convicted of DUI (Chapter 12).

Only TIME removes alcohol: Coffee, food, cold showers, and fresh air do NOT lower your BAC. Your liver processes about 1 drink per hour — nothing speeds this up.

Impairment starts with the first drink: You can be convicted of DUI even below .08% if your driving is impaired. Judgment and reaction time suffer immediately.

Zero Tolerance under 21: It is illegal for anyone under 21 to purchase, possess, or drink alcoholic beverages. You can be arrested for alcohol impairment at any measurable amount (under 21) BAC (Chapter 12). If your BAC reaches 0.08% or higher, the same DUI penalties as adults apply. Do not drive after drinking at any level if you are under 21.

Mixing drugs and alcohol: Mixing drugs (even prescription or over-the-counter) with alcohol is especially dangerous — the combination multiplies harmful effects on coordination and concentration. This can lead to serious health problems and even death (Chapter 12).

Wireless device restriction: Learner Permit and Intermediate License holders may NOT use any wireless communication device while driving — no calls, texts, or browsing. Exceptions only for reporting illegal activity or summoning emergency help (Chapter 1–12). Oklahoma law also prohibits ALL drivers from writing, sending, or reading texts/emails while driving (Oklahoma law).

Drugs and driving: Driving while impaired by any drug — prescription, over-the-counter, or illegal — is a DUI offense in Oklahoma. Even legally prescribed medications that affect your driving ability can lead to a DUI charge. First drug DUI conviction: misdemeanor penalties: not less than 10 days jail, fine up to $1,000 (Chapter 12). Check medication labels or ask your doctor before driving.

🚌

School bus rules are heavily tested. In Oklahoma, you must stop for a school bus with red lights flashing from ANY direction — with only limited exceptions. Traffic in BOTH directions must stop. All other traffic from BOTH directions must stop (Oklahoma Driver Manual).

🚌

School Bus Stopping Rules

HEAVILY TESTED

Two-lane road / undivided road: ALL traffic in BOTH directions must stop when a school bus has flashing red lights and the stop arm is extended. No exceptions.

Divided highway exception: You do NOT need to stop if you are approaching from the opposite direction on a divided highway. Note: the Oklahoma manual simply states "divided highway" — it does not require a median or physical barrier specifically. All other situations — stop from both directions (Oklahoma Driver Manual).

Same direction — always stop: Traffic traveling in the same direction as the bus must ALWAYS stop, regardless of road type or number of lanes (Oklahoma Driver Manual).

After the bus stops: Remain stopped until one of these three things happens: (1) the bus has started moving, OR (2) the driver motions for you to proceed, OR (3) the red flashing lights go off and/or the stop sign is pulled back. Then proceed slowly, watching carefully for children near the roadway (Chapter 5).

When may you proceed: Only when ONE of the three conditions above is met. Not when children step back — wait for the bus driver's signal, the lights to stop, or the bus to move.

Yellow lights = warning: Yellow flashing = bus is about to stop. Slow down immediately and prepare to stop. Do not try to pass before it stops.

One of the most tested topics: School bus stop questions appear on nearly every Oklahoma SOK knowledge test. Know the divided highway median exception — all traffic (both directions) must stop unless on a divided highway.

School buses must stop at ALL railroad crossings — regardless of whether warning signals are active. This is federal law.

Mandatory 1-year revocation: Failing to stop for a school bus with flashing red loading/unloading lights results in mandatory revocation of your driver license for one year (Chapter 5).

Speed Laws — What You Must Know

ON EVERY TEST

Basic Speed Law: Drive at a speed that is reasonable and proper for existing conditions — even if that means going below the posted limit. Rain, fog, heavy traffic, school zones all require reduced speed.

Posted limits are MAXIMUMS: You may never legally exceed a posted limit, regardless of conditions, traffic, or what other drivers are doing.

Minimum speed law: Do not drive so slowly that you impede or block the normal flow of traffic. Driving too slowly is also illegal.

Work zone caution: Reduce speed in work zones even when workers are not present. Fines for speeding in a work zone are doubled in Oklahoma (Okla. Stat.). Give construction workers a "brake."

"Over-driving your headlights": Oklahoma requires headlights beginning 30 minutes after sunset until 30 minutes before sunrise. Also when road signs require it, or in fog, rain, or snow. Never drive faster than you can stop within the distance you can see (Oklahoma Driver Manual).

↔️

Following Distance — The 3-Second Rule

TESTED

Pick a fixed object — a sign, overpass, or lane marking ahead

When the car ahead passes it, start counting: "one-one-thousand, two-one-thousand, three-one-thousand"

If you pass the object before 3 seconds — you are following too closely. Slow down. In bad weather or poor conditions, increase to the 4-second rule (Chapter 8).

💡 When to increase beyond 3 seconds

Rain, snow, ice, or fog → 4 seconds minimum (adverse rule)
Driving at night → increase beyond 3 seconds
Following a large truck or motorcycle → increase distance
Towing a trailer → more distance needed
Driving at highway speeds → increase distance proportionally

📐

Passing Rules

TESTED

✓

You MAY pass when: There is a broken yellow line on your side, you have sufficient sight distance, and there is no sign or condition prohibiting passing.

✗

NEVER pass: On hills or curves where you cannot see oncoming traffic; within 100 feet of a railroad crossing, bridge, or intersection; in no-passing zones (solid yellow on your side); near school buses; when it would require going off the road.

→

When it is safe to return: Do not return to the right lane too soon — wait until you can see the entire front of the vehicle you just passed in your rearview mirror (Oklahoma Driver Manual).

→

Passing on the right: Legal when the vehicle ahead is making a left turn and there is a safe lane to the right, or on a multi-lane road.

🅿️

Parking Clearance Requirements

TESTED

Location	Minimum Clearance
Fire hydrant	15 feet — do not park within 15 ft of a fire hydrant (Chapter 9)
Traffic signal, stop sign, or flashing beacon	30 feet — do not park within 30 ft approaching any of these (Chapter 9)
Crosswalk at intersection	20 feet — do not park within 20 ft of a crosswalk at an intersection (Chapter 9)
Railroad crossing	50 feet — do not park within 50 ft of the nearest rail (Chapter 9)
Fire station driveway	20 feet (same side) / 75 feet (opposite side) (Chapter 9)
More than 18 inches from curb	Do not park more than 18 inches from a curb (Chapter 9)
Driveway entrance	Not in front of — always prohibited
Handicapped space (without placard)	Never park here
Inside an intersection / on crosswalk / on sidewalk	Never — always illegal (Chapter 9)
Bridge, overpass, or tunnel	Never — always prohibited (Chapter 9)

⛰️

Parking on Hills — Wheel Position

TRICK QUESTION

💡

The rule: always turn wheels so that if the car rolls, it rolls away from traffic or is caught by the curb.

Situation	Turn Wheels	Why
Facing DOWNHILL, WITH curb	RIGHT (into curb)	Car rolls into curb and stops
Facing DOWNHILL, NO curb	RIGHT (away from road)	Car rolls away from traffic
Facing UPHILL, WITH curb	LEFT (away from curb)	Car rolls back, caught by curb
Facing UPHILL, NO curb	RIGHT (away from road)	Car rolls away from traffic

💡 Memory trick

Going downhill with a curb = wheels RIGHT into the curb
Going uphill with a curb = wheels LEFT, away from curb (tire catches it when rolling back)
No curb either way = wheels RIGHT, away from road

🎓

GDL questions appear on many tests, especially for younger test-takers. Know the phases, key restrictions, and specific numbers for Oklahoma's Graduated Driver License program.

🎓

Oklahoma Graduated Driver License (GDL)

ON EXAM

Phase 1 — Learner Permit

→

Minimum age: 15 years old (with proof of enrollment in or completion of an approved driver education course). Without driver education: minimum age 16. Must pass vision and written examination (Chapter 1).

→

Learner Permit valid only while a licensed driver 21 or older is seated beside the driver. Driving test can be taken 180 days (6 months) after the permit is issued (Chapter 1).

→

Supervisor: must be a licensed driver at least 21 years old, seated beside the driver at all times. No special experience requirement beyond having a valid license (Chapter 1).

Phase 2 — Intermediate License (Class D)

→

Age 16 (with driver education): Must show completion of an approved driver education course, have held permit at least 180 days, AND present a Work Zone Safe completion certificate. Intermediate restriction ("T" restriction) is applied to the license (Chapter 1).

→

Age 16½ (without driver education): Driver education completion not required. Must have held Learner Permit for at least 180 days. Intermediate restriction applies until age requirements met (Chapter 1).

→

GDL "T" Restriction — Driving Hours: Driving allowed from 5 a.m. to 10 p.m. Exceptions: driving to/from school, church, work or related activities, OR any time if a licensed driver at least 21 years old is seated in the front passenger seat (Chapter 2).

→

Passenger Restriction: Only 1 passenger allowed unless all passengers live in the driver's same household — OR a licensed driver 21+ is in the front passenger seat (Chapter 1).

→

Removing the Intermediate Restriction: If driver education was completed, restriction removed after 6 months. If no driver education, restriction removed after 1 year (Chapter 1).

→

Probationary Period: All licenses issued to drivers under 18 are probationary. Service Oklahoma may cancel or suspend for any moving traffic violation, negligence, or misconduct. If convicted of a moving violation, you remain at your GDL level until 6 months from the conviction date (Chapter 2).

Phase 3 — Regular Class D License (age 18+)

→

Age 18: No "T" restriction applied. Full Class D privileges. Driver education not required for applicants 18+. License is no longer probationary (Chapter 1, Chapter 2).

→

BAC: ANY measurable alcohol = unlawful for under 21 (Zero Tolerance). BAC 0.08%+ is the DUI threshold for drivers 21+ (Chapter 12).

→

Electronic devices: Learner Permit or Intermediate License holders can have their license suspended or canceled for using a hand-held electronic device while driving (Chapter 11).

🛡️

Emergency Situations — What to Do

TESTED

💨

Tire blowout: Hold the wheel FIRMLY. Ease off gas (don't brake suddenly). Let the car slow naturally. Then gently steer to safety. Sudden braking causes a spin.

💧

Hydroplaning: Ease off gas, hold wheel steady, avoid braking. Let tires re-contact the road. Don't jerk the wheel or brake hard.

🔥

Engine fire: Pull over immediately, turn off engine, get EVERYONE out and move far away (100+ feet). Call 911. Never open the hood.

⚡

Brakes fail: Pump brakes rapidly to build pressure. Downshift to use engine braking. Use parking brake carefully (gradually). Steer to safety.

🌊

Accelerator sticks: Shift to NEUTRAL immediately. Apply brakes. Pull over. Turn engine off.

🌀

Vehicle skids: Ease off gas and brakes. Steer in the direction you want the front to go (into the skid). Do not overcorrect.

🚂

Stalled on railroad tracks: Get EVERYONE out IMMEDIATELY. Move away at a 45° angle in the direction the train is coming — so debris flies away from you. Call 911 and the railroad ENS number.

🌫️

Driving in fog: Use LOW beams (high beams reflect off fog and blind you). Slow significantly. Use fog lights if available. Consider pulling over.

😴

Drowsy driving: Only cure = sleep. Pull over and rest. Coffee, window down, and music are NOT effective solutions. Drowsy driving equals drunk driving in impairment level.

❄️

Stranded in a blizzard: Stay in the vehicle (it's shelter and visible). Run engine briefly for heat with window cracked to prevent CO poisoning. Signal for help with hazards.

🧠

Defensive Driving Principles

ESSENTIAL

Scan ahead: Maintain a visual lead of 15 to 20 seconds ahead of your vehicle (Chapter 6). Watch for cars braking, entering and exiting well ahead. Check mirrors regularly when slowing, changing lanes, or going downhill (Oklahoma Driver Manual).

Keep an escape route: Always know where you could go if the car ahead stopped suddenly.

Bridges freeze first: Cold air circulates above AND below a bridge. Bridges ice before road surface — always treat them as potentially icy in winter.

Head-on collision approaching: Brake hard and steer RIGHT — even off the road. A head-on crash at speed is almost always fatal; going off-road is survivable.

Road rage: Never engage, retaliate, or make eye contact. Don't respond with gestures. Slow down, create distance. Report to 911 if dangerous.

Front wheel off pavement: Don't jerk the wheel — it can roll the car. Ease off gas, brake gently, and gradually steer back. Hold on tight.

🔧

Vehicle Equipment Requirements

TESTED

Equipment	Requirement
Headlights (on)	Required beginning 30 minutes after sunset and until 30 minutes before sunrise. Also required when road signs state headlights must be used. Use low beams in fog, rain, snow, or adverse conditions (Chapter 11).

When headlights are required by Oklahoma law: Turn on headlights beginning 30 minutes after sunset and keep them on until 30 minutes before sunrise (Chapter 11). Also use when a road sign requires it, and always use low beams in fog, rain, snow, or adverse weather.

Parking lights ≠ headlights: Parking lights are only for indicating a parked vehicle. They are NOT adequate for driving — always use headlights when moving at night.

Fog lights vs. high beams: In fog, use LOW beams or fog lights. High beams reflect off water particles and reduce your own visibility.

Don't overdrive your headlights: Never drive faster than you can stop within the distance lit by your headlights. Reduce speed at night on dark highways and country roads (Chapter 7).

Before the Test — What to Do

PREPARATION

Take the SOK Exam Simulator at least 5 times and score 90%+ consistently. Don't go in when you're scoring 80% — aim higher than the minimum.

Use the "Weak Spots" mode the night before. Every question you got wrong — review those explanations until you understand WHY, not just what the answer is.

Memorize the Key Numbers tab — BAC limits, speed limits, distances, suspension periods. These come up constantly on the real test.

Get a good night's sleep. Drowsy test-taking impairs recall just like drowsy driving impairs reaction time.

Bring required documents: Your full legal name ID (certified birth certificate or passport), Social Security Number, proof of auto liability insurance (if taking driving test), and proof of Oklahoma residency. If you fail the written test, you must wait at least 1 day before retesting (Chapter 1).

🧠

During the Test — How to Answer

STRATEGY

The safest answer is usually correct. When in doubt, pick the option that is most cautious, most yields, or stops the most. Oklahoma tests reward safe, defensive driving choices.

Watch for "NEVER" and "ALWAYS" options. These are sometimes traps — but in Oklahoma driving law, there actually are many absolute rules (ALWAYS stop for school bus, NEVER pass on a hill crest, etc.).

"All of the above" is very often the correct answer on SOK knowledge tests — especially for questions about DUI charges, suspension triggers, and violations.

Read every word. Test questions often hinge on words like "divided highway" vs. "undivided," "business district" vs. "residential," or "first offense" vs. "subsequent offense."

Refuse = worse than fail. For DUI questions: refusing a chemical test always has a longer suspension than failing it. This surprises many people.

The real SOK written test: score 80% to pass. Road signs are included — there is no separate signs test. Our simulator uses 50 questions to give you full prep coverage.

DMV Written Test · Recommended Study Approach

The Smartest Way
to Pass Your Test

A proven 4-phase approach that builds real understanding — not just memorization. Work through each phase at your own pace, and you'll walk into the DMV ready to pass on your first try.

📱 Uses This App 🎯 50 Qs · 80% to Pass 🧠 4 Phases · Your Pace ✅ 90%+ Before You Go

⚡ How This Approach Works

🧠

Learn before you quiz. Read the material first so practice questions teach you patterns — not just random answers.

🎯

Fix what's weak, skip what's strong. The app tracks every wrong answer. Spend your time where it matters most.

📈

Build up gradually. Numbers → Study Guide → Practice → Topics → Simulator. Each phase builds on the last.

🏁

Don't go until you're ready. Score 90%+ on the 30-minute simulator twice before visiting the DMV. You can miss up to 10 out of 50 — but aim higher.

🧠 Phase 1 Learn — Build Your Foundation

🔢

Step 1 · Start Here

Memorize the Key Numbers

Study Guide → 🔢 Key Numbers tab · then take the Key Numbers Quiz

⏱ 30–40 min

Click in the top bar → open the tab.

Read every number out loud. Speed limits, distances, BAC limits, suspension periods. Saying them out loud forces your brain to process them more deeply.

Write these on paper: 80 · 75 · 65 · 55 · 35 · 25 · .08 · any amount (under 21) · 100ft · 15ft · 20ft · 30ft · 50ft · 18in curb · 6in hill · 180 days · 3sec · 4sec · $1,000 max DUI

Go home → click . Take it without your notes. Check your score.

Under 85%? Re-read the Key Numbers tab, then retake the quiz. Repeat until you hit 85%+.

💡

Why numbers first? At least 5–10 of your real knowledge test questions will ask for a specific number. These are free points if you know them — and guaranteed wrong answers if you don't.

📖

Step 2 · The Big 4 Topics

Read the 4 Most-Tested Study Tabs

Study Guide → Right of Way · Alcohol & DUI · Road Signs · Signals & Lanes

⏱ 40–50 min

— read completely. This is the #1 failure topic. Understand left turns at green lights and Oklahoma's school bus rule (ALL traffic both directions stops — with limited exceptions including approaching from the opposite direction on a divided highway (Oklahoma Driver Manual)).

— key facts: first DUI: misdemeanor, 10 days–1 year jail, fine up to $1,000. Implied Consent: 180-day revocation if BAC test failed at scene. Refusal = 180 days–2 years revocation (Chapter 12). Refusing (180 days–2 years) always results in a longer revocation than failing the BAC test (Chapter 12).

— shapes and colors tables. Octagon = stop, triangle down = yield, diamond = warning, pentagon = school zone, pennant = no passing.

— flashing red vs. yellow, green arrow vs. regular green, when left-on-red is allowed (one-way street turning onto another one-way street, after complete stop and yielding to traffic and pedestrians).

ℹ️

Don't try to memorize every word. Focus on understanding WHY each rule exists. When you understand the reasoning, you can figure out answers even when questions are worded differently from what you studied.

📖

Step 3 · The Rest of the Guide

Read the Remaining Study Tabs

School Buses · Parking · Teen Laws · Speed & Following · Safe Driving · Equipment

⏱ 30–40 min

— ALL traffic BOTH directions must stop when red lights flash. Exception only if: (1) the bus is on a different roadway, (2) stopped at a controlled-access highway loading zone where pedestrians cannot cross, or (3) you are approaching from the opposite direction on a divided highway. Always on the test.

— memorize the 4 hill parking scenarios. Oklahoma uses 18 inches from curb for parallel parking. Hill parking trick: no curb = always turn wheels right (toward edge of road).

— Oklahoma GDL: Learner Permit at 15 (with DE) or 16 (without) → hold permit 180 days → Intermediate License at 16 or 16½ (+Work Zone Safe certificate) → T restriction removed after 6 months (with DE) or 1 year (without) → full Class D at 18. Driving: 5 a.m.–10 p.m. + school/work/church exceptions.

— 3-second rule (or 1 car length per 10 mph) / 4-second in adverse conditions, passing rules, and when to increase your following distance (Oklahoma Driver Manual).

— hydroplaning, blowout, skid recovery, fog driving. Understand the logic — don't memorize.

— headlights required 30 min after sunset until 30 min before sunrise. Dim high beams within 1,000 feet of an oncoming vehicle or 600 feet of a vehicle you are following (Chapter 11). Use low beams in fog, rain, or snow.

✅

Pro tip: If you want even deeper detail, download the 📕 Official Oklahoma Driver Manual → for the full official content. The study guide gives you the highlights, the manual gives you everything.

☕ Take a real break here. Sleep on it if you can — your brain consolidates memory overnight. Phase 2 works best after at least a few hours (or a night) away from studying.

📝 Phase 2 Practice — Test Yourself

📚

Step 4 · First Practice Run

Full Practice Bank — Work Through 60–100 Questions

Home → 📚 Full Practice Bank · no timer, read every explanation

⏱ 45–60 min

Click . This gives you all 530+ questions in random order with no timer.

Read every explanation — even when you get it right. The explanations contain extra detail and reasoning that will help you on tricky test questions.

Do at least 60–100 questions. The app automatically saves every wrong answer so you can drill them later.

Click See Results when done. Note which categories you failed most — those are the targets for Phase 3.

ℹ️

Getting things wrong is the point. This is a learning session, not an exam. Every wrong answer you discover now is one you'll get right on test day.

🏆

Step 5 · Topic Deep-Dives

Practice Your 3 Weakest Categories

Home → Choose Your Practice Mode → pick Full Practice Bank or Quick Drill

⏱ 30–40 min

Look at your results from Step 4. Find the 3 categories where you got the most wrong (e.g., Right of Way, DUI, Road Signs).

Use the Study Guide to review your weak topics, then run the Full Practice Bank or Quick Drill to test yourself on all categories.

Repeat for your 2nd and 3rd weakest topics. Focused drilling is much more efficient than random practice.

Target: 80%+ on each topic. Under 80%? Go back to the Study Guide tab for that topic, re-read it, then retake.

🎯 Phase 3 Fix — Attack Your Weak Spots

🎯

Step 6 · The Most Important Step

Weak Spots Mode — Drill Every Wrong Answer

Home → 🎯 Weak Spots Only · the app loads your mistakes automatically

⏱ 30–45 min

Click . The app loads every question you've gotten wrong so far — automatically.

Before you answer — think about why each option might be right or wrong. Slow down and reason through it.

Still don't understand an answer? Open the Study Guide tab for that topic and re-read just that section. Or download the official Oklahoma Driver Manual for the full official explanation.

Retake Weak Spots until you score 85%+ on it. 2–3 rounds is completely normal — that's exactly how this is supposed to work.

⭐

This is the single most valuable thing you can do. Research shows that practicing things you got wrong is 3–5x more effective than re-reading material you already know. Don't skip this step.

☕ Take a break. At least 30 minutes. Let your brain rest before the simulation phase.

🏁 Phase 4 Prove It — Simulate the Real Test

📋

Step 7 · The Big Test

SOK Exam Simulator — Full Simulation

Home → 📋 SOK Exam Simulator · 50 questions · 30-min timer

⏱ 20–30 min

Click . 50 random questions, 30-minute simulator countdown, need 40/50 (80%) to pass. The real Oklahoma test has no official time limit.

Treat it like the real thing. No notes. No Study Guide. Sit quietly, read every question fully, and give your best answer.

Check your score against the table below and follow the action for your result.

Your Score	Status	What to Do Next
Under 75%	Needs more work	Go back to Phase 3 — run Weak Spots mode on your wrong answers. Re-read the Study Guide for those topics. Then try the simulator again.
75% – 89%	Almost there	Run Weak Spots on what you missed, then take the simulator again. You're close — one more round should get you there.
90%+	Ready! 🎉	Run the simulator one more time to confirm. Score 90%+ twice → you are ready for the real test.

🔁

Step 8 · Repeat Until 90%+

Fix → Retest → Confirm

Retry Wrong Ones → DMV Simulator → repeat until you pass twice in a row

⏱ 30–45 min per cycle

From the results screen click . Drill every question you got wrong in the simulator.

For any question you still don't understand — open the Study Guide, find the right section, and re-read that rule. Or download the official Oklahoma Driver Manual for the full explanation.

Run the again. Keep going until you hit 90%+ twice in a row.

✅

The magic number is 90% twice. If you can score 90% on random questions under timed conditions two times in a row, you know the material — not just the specific questions.

🌙 Night Before Refresh — Don't Cram

🌙

Final Review — 20 Minutes Max

Quick Refresh, Then Sleep

Key Numbers tab + Test-Day Tips tab only · No new material

⏱ 20 min max

Open tab in the Study Guide. Read through once — don't study, just refresh.

Open the tab. Read the strategy section — especially "safest answer wins" and "refuse = worse than fail."

Take one as a confidence check. Score 80%+? Close the app and go to sleep. You're ready.

Go to sleep at your normal time. Being well-rested is worth more than another hour of studying.

⚠️

Do NOT cram the night before. Your brain needs sleep to consolidate everything you've learned. More than an hour of study at this point actually hurts performance.
