📖 South Carolina SCDMV Study Guide

Everything important from the South Carolina Driver's Manual — organized for the exam

⭐

Memorize these numbers first. South Carolina SCDMV test questions are frequently built around specific distances, speeds, BAC levels, and time periods. These come up constantly.

Speed Limits

HIGH FREQUENCY

Posted

Always obey the posted speed limit — it is the maximum legal speed in ideal conditions (6-10).

School zones

Obey the posted reduced limit when lights are flashing or children are present. Stop and yield if signaled by a school crossing guard (10-2).

55 mph

Maximum recommended speed for most vehicle-trailer combinations. Reduce further in poor conditions — never exceed the posted limit (11-11).

≤ 35 mph

A golf cart may only operate on secondary streets/highways with posted limits of 35 mph or less, within 4 miles of the address on the registration certificate (2-2).

4 sec

Minimum following distance on dry pavement. Pick a fixed object — if you reach it before counting to four, you are too close (8-6).

+1 sec

At night, add at least 1 extra second of following distance. Add 2+ additional seconds on unfamiliar roadways at night (11-2).

📏

Critical Distances & Clearances

HIGH FREQUENCY

200–300 ft

Place emergency flares 200 to 300 feet behind a disabled vehicle to warn approaching traffic (9-5).

Up to 200 ft

Large trucks have rear blind spots ("no zones") that extend up to 200 feet. If you can't see the driver's mirrors, they can't see you (10-9).

Stop line

At a red light, stop sign, or railroad crossing, stop behind the stop line or crosswalk — not past it (6-15).

RR crossing

At active railroad crossings, stop behind the stop line or tracks until the train has passed and devices indicate safe to cross (6-6).

18 in

When parallel parked, your vehicle must be within 18 inches of the curb or edge of pavement (7-12).

Front bumper

When passing, return to your lane only when the complete front of the passed vehicle is visible in your rearview mirror (7-16).

500 ft / 200 ft

Dim your high beams within 500 ft of an oncoming vehicle. Use low beams when following within 200 ft of another vehicle (11-1, 11-2).

Low beams

In fog, rain, or snow, use low beams. High-beam light causes glare and reduces visibility ahead (11-2).

100 ft

Signal 100 ft or more before changing lanes, turning, merging, or passing. Cancel your signal when done (7-16, 8-9).

Primary

SC has primary safety-belt enforcement — an officer may stop you solely for an unbelted driver or occupant in clear view (4-5, 4-6).

Extra space

Slow down when passing a bicyclist and allow as much space as possible. Consider their speed — do not force them toward parked cars (7-16, 10-3).

2-lane: all stop

School bus with red/amber lights on a 2-lane road: ALL traffic both ways stops. On a 4+ lane highway: only traffic BEHIND the bus stops (7-8, 7-9).

🍺

DUI & Alcohol Numbers

ALWAYS ON TEST

0.08%

Per-se BAC limit for drivers 21+. You can still be convicted of impaired driving at 0.05% or lower if combined with prescription, OTC, or illegal drugs (3-7).

0.02%

Zero-tolerance BAC limit for drivers under 21. BAC 0.02%+ = immediate 3-month license suspension on first offense (3-7).

0.15%

BAC of 0.15% or higher triggers enhanced penalties and additional suspension (3-7).

6 months

Implied consent refusal — refuse a breath, blood, or urine test and driving privileges are suspended immediately for at least 6 months (3-7, 3-8).

40%

About 40% of all traffic collisions in which someone is killed each year involve alcohol or other impairing drugs (3-6).

🎓

Teen / GDL Numbers

ON EXAM

Age 15

Minimum age for a SC beginner's permit. Vision + knowledge test required. Licensed driver 21+ with 1 yr experience must be in front seat (1-4).

Age 15½

Minimum age for a conditional license (15½ to less than 16). Drive alone 6 a.m.–6 p.m. (8 p.m. DST); supervisor 21+ required 6 p.m.–midnight (1-7).

6 p.m.–midnight

Conditional/special-restricted curfew — licensed driver 21+ required 6 p.m. (8 p.m. DST) to midnight. After midnight, a listed supervisor only (1-7, 1-8).

2 under 21

Max 2 passengers under 21 unless a licensed 21+ adult is present. Exception: transporting family or students to/from school (1-7, 1-8).

180 days

Minimum permit hold for applicants 17 and under. Applicants 18+ must hold the permit at least 30 days (1-4, 1-5).

Age 17

Full unrestricted license at 17, or after 1 year of conditional/special restricted with no traffic offenses or at-fault collisions (1-9).

⏱️

Following Distance & Time Rules

ON EXAM

4 seconds

Minimum following distance on dry pavement in SC. Pick a fixed object — if you reach it before counting to four, you are following too closely (8-6).

4+ sec

Behind motorcycles (especially in wet conditions), in rain/snow/fog, behind trucks/buses/vehicles pulling a trailer, and behind vehicles required to stop at railroad crossings (10-6, 8-6, 8-7).

158 ft

Braking distance at 50 mph on dry pavement with good brakes. Add perception (¾–1 sec) + reaction (¾–1 sec) time on top (8-5).

Hands-Free

SC Hands-Free and Distracted Driving Act: no holding a device, no texting/email/app use, no viewing moving images. 1st offense: $100. 2nd+: $200 + 2 points (3-4, 3-5).

🚦

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 ZONE	School crossing
Pennant (triangle right)	NO PASSING ZONE	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. In SC, endangering a highway worker may result in a fine and points against your driving record (SC Code §56-5-1535) (11-3).
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 SCDMV 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 regardless of where they are crossing.

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.

Move-Over Law: When you approach a stopped authorized emergency vehicle with lights on, slow down and yield right-of-way by changing lanes away from it if safe. If a lane change is unsafe, slow down and proceed with caution while maintaining a safe speed (10-14, 10-15).

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: Legal ONLY when turning from a one-way street onto another one-way street — after a complete stop and yielding.

🚥

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 — SC law requires using a turn signal 100 feet or more before turning or changing lanes (8-9).

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 SCDMV knowledge test. Know the BAC levels, implied consent law, and penalties. South Carolina uses the term "DUI" (Driving Under the Influence).

🍺

DUI Laws — The Numbers You Must Know

ALWAYS ON TEST

Situation	Consequence
BAC of 0.08%+ (driver 21+)	DUI or DUAC under SC law — mandatory license suspension. Penalties escalate with BAC level and prior offenses. A provisional DL is NOT available for DUI/DUAC on or after May 19, 2024 (3-7, 1-21).
Impairment below 0.08% BAC	You can still be convicted of impaired driving at 0.05% BAC or lower when combined with prescription or over-the-counter drugs (3-7).
Test refusal (implied consent)	Refusing a lawfully-requested breath, blood, or urine test = immediate loss of driving privileges for at least 6 months (3-7, 3-8).
BAC — under 21 (Zero Tolerance)	A BAC of 0.02% or higher suspends the license immediately for at least 3 months (3-7).
BAC of 0.15% or higher	Enhanced penalties and additional suspension (3-7).
DUI — drugs	Treated the same as a DUI or DUAC conviction, whether the substance is prescription, over-the-counter, or illegal (3-9).

💡

Critical DUI Facts to Remember

TESTED

Implied consent: By holding an SC driver's license, you have consented to lawfully-requested breath, blood, or urine tests if suspected of impaired driving. Refusal = immediate suspension of at least 6 months (3-7, 3-8).

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: Judgment is the first driving ability affected. In SC you can still be convicted of impaired driving at a BAC of 0.05% or lower when combined with prescription or OTC drugs (3-7).

Under-21 Zero Tolerance: A BAC of 0.02% or higher for a driver under 21 suspends the license immediately for at least 3 months — even well below the adult 0.08% limit (3-7).

Mixing drugs and alcohol: Never combine alcohol with prescription or OTC drugs. Combinations may multiply the effects of alcohol, reduce driving ability, and cause serious health problems (3-9).

Hands-Free Act: While driving on any SC public road you may not hold or support a mobile device with any part of your body, read/write/send text, or view moving images. 1st offense $100; 2nd+ $200 + 2 points (3-4, 3-5).

Drugs and driving: Driving while impaired by any drug — prescription, over-the-counter, or controlled — is illegal. Even legally prescribed medications that impair your ability to drive can lead to a DUI charge.

🚌

School bus rules are heavily tested. On a 2-lane road, ALL traffic in both directions must stop when a school bus shows red or amber flashing lights or has its stop arm extended. On a 4+ lane highway (2+ lanes each way), only traffic BEHIND the bus must stop; oncoming traffic may proceed with caution (7-8, 7-9; SC Code §56-5-2760).

🚌

School Bus Stopping Rules

HEAVILY TESTED

Two-lane / undivided road: ALL traffic in both directions must stop when a school bus has red or amber lights flashing or stop arm extended (7-8, 7-9).

4+ lane highway — oncoming exception: On a highway with 4 or more lanes (2+ in each direction), you do NOT have to stop when traveling in the OPPOSITE direction of a stopped bus (7-9).

Loading-zone exception: You do NOT have to stop if the bus is in a passenger loading zone completely off the main travel lanes AND pedestrians are not allowed to cross the roadway there (7-9).

Same direction — always stop: Traffic BEHIND the bus must ALWAYS stop, regardless of road type or number of lanes (7-9).

After the red lights stop flashing: Remain stopped until the bus moves or the red lights stop flashing. Then proceed slowly, watching carefully for children (7-8, 7-9).

Amber (yellow) lights = warning: Bus is preparing to stop. You must stop for the entire time the bus is stopped or preparing to stop with red OR amber lights flashing (7-8).

Passing a stopped bus: Stopping is required when attempting to pass a school bus that has red or amber signals flashing (7-9).

"Multi-lane highway" defined: A highway or private road that consists of four lanes with at least two traffic lanes in each direction (7-9).

Shortcut for the test: 2-lane road = everyone stops. Behind the bus = always stop. 4+ lane highway opposite direction = you may proceed.

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: Always reduce speed in a work zone — even if no workers are present. If you endanger a highway worker you may be fined and have points assessed against your record (SC Code §56-5-1535) (11-3, 11-4).

"Over-driving your headlights": Never drive faster than you can stop within the distance your headlights illuminate at night. Use low beams in fog, heavy rain, sleet, or snow — high beams cause glare and reduce visibility (11-2).

Four-Second Following Rule: Pick a stationary object ahead. When the vehicle in front passes it, count "one-thousand-one, one-thousand-two, one-thousand-three, one-thousand-four." If you reach the object before four, you are following too closely (8-6).

↔️

Following Distance — The 4-Second Rule

TESTED

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

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

If you pass the object before 4 seconds — you are following too closely. Reduce speed and check again (8-6).

💡 When to increase beyond 4 seconds

Slippery roads — rain, snow, ice, or fog
At night: add at least 1 second (2+ on unfamiliar roads) (11-2)
Following a motorcycle, especially in wet conditions (10-6)
Following a large truck, bus, or vehicle pulling a trailer
Behind vehicles required to stop at railroad crossings (buses, hazmat)

📐

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: When an oncoming vehicle is approaching, your view is blocked by a curve or hill, at intersections, or before a highway-railroad crossing or bridge. Never pass on the shoulder — it is for emergency stopping only. Never pass a school bus with red or amber lights flashing (7-15, 7-16, 7-9).

→

When it is safe to return: You may move back into your original lane when both headlights of the passed vehicle are visible in your rearview mirror.

→

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	SCDMV Rule
Distance from curb when parallel parked	Within 18 inches of the curb or edge of pavement (7-12)
Parking along a roadway (any side)	Park as far from the flow of traffic as possible (7-10)
Handicap / disability space	Only if the vehicle is driven by or transporting the person named on the disability plate or placard registration (7-10)
No-parking zones	Check for signs or painted curbs. Some restrictions are indicated by colored curb markings (7-11)
Perpendicular / angle parking	Center your vehicle in the space; back straight until your front bumper clears adjacent vehicles before turning the wheel (7-11)
Before opening your door on the street	Check sides and rear of vehicle for bicyclists and traffic (10-5)
Leaving a parking space	Signal, use mirrors, look over your shoulder, and yield right-of-way (7-13)
Inside an intersection or on a crosswalk	Never — always illegal
In front of a driveway entrance (public or private)	Always prohibited

⛰️

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. Know South Carolina's Graduated Driver Licensing program, the restrictions in each phase, and the specific ages, hold periods, and curfew hours.

🎓

South Carolina Graduated Driver Licensing (GDL)

ON EXAM

Phase 1 — Beginner's Permit (age 15+)

→

Minimum age: 15 years old. Pass vision and knowledge test. Applicants under 18 need parent/legal guardian consent (SCDMV Form 447-CM). Permit fee: $2.50 per year (1-4).

→

Hold period: at least 180 days if you are 17 or under; at least 30 days if you are 18 or older (1-4, 1-5).

→

Supervisor: a licensed driver at least 21 years old with at least one year of driving experience must be in the front passenger seat with you. Driving hours 6 a.m.–midnight with this supervisor; after midnight, a listed legal supervisor per SC Code §56-1-100(A)(1-7) (1-4).

→

If 15 or 16: you must log at least 40 hours of supervised practice — including 10 hours at night — with a listed supervisor before applying for a license. Must complete driver's education (8 hrs classroom + 6 hrs driving) (1-5, 1-6).

Phase 2 — Conditional / Special Restricted License (age 15½–17)

→

Eligible at 15½ to less than 16 (conditional) or 16 to less than 17 (special restricted). Must pass vision and skills test. Must complete driver's ed and 40 hrs supervised practice (10 at night) (1-7, 1-8).

→

Restrictions: drive alone 6 a.m. to 6 p.m. (8 p.m. during DST). 6 p.m.–midnight requires a licensed driver 21+. After midnight requires a listed supervisor. Max 2 passengers under 21 unless a licensed 21+ adult is present (exception: family/students to-from school). Under-17 drivers with 6+ points in the first year = 6-month suspension (1-7, 1-8).

→

SC Hands-Free and Distracted Driving Act applies to ALL drivers regardless of age: no holding a mobile device, no texting/email/app use, no viewing moving images. 1st offense $100; 2nd+ $200 + 2 points (3-4, 3-5).

🛡️

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: Shift to a lower gear. Use the parking brake gradually. Look for a safe area to slow to a stop. Rub a tire on the curb if needed.

🌊

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 from the vehicle and the tracks. Locate the Emergency Notification System (ENS) sign for emergency contact information, and call for help — tell them a vehicle is on the tracks.

🌫️

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: Look well ahead of your vehicle — at least a city block in town and farther on highways. Check mirrors every few seconds and whenever slowing, changing lanes, or approaching intersections.

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	Turn on when visibility is reduced — rainy, snowy, or foggy days, and at dusk or dawn. Use low beams in fog, rain, or snow (8-8, 11-2).
High beams — dim distances	Dim when within 500 ft of an oncoming vehicle. Use low beams when following within 200 ft of another vehicle (11-1, 11-2).
Horn	Use when needed to prevent a crash — a light tap is usually enough. Avoid around blind pedestrians and animal-drawn vehicles (8-8, 8-9, 10-16).
Turn signals	Signal 100 feet or more before changing lanes, turning, merging, or passing. Cancel signals once your action is complete (7-16, 8-9).
Tire tread depth	Check monthly using the Lincoln-penny test. If the top of Lincoln's head shows, tires are too worn — replace them (4-2).
Tire pressure	Check monthly with a pressure gauge when tires are cold. Compare against the PSI on the driver's-side doorframe sticker (4-1, 4-2).
Head restraints	Adjust so the restraint contacts the back of your head — not below the ears. Designed to prevent whiplash (4-3).
Steering-wheel clearance	At least 10 inches between your chest and the steering wheel for safe airbag deployment (4-3).
Skills-test vehicle checklist	Working headlights, brakes, mirrors, safety belts, defroster, turn signals, horn, windshield wipers, speedometer. Valid plate, registration, insurance card (1-11, 1-12).
Safety features during skills test	You may NOT use parking assist or cruise control during the driving test (4-9).
Hazard lights	Use when your vehicle is disabled to warn other drivers (9-5).
Seat belts & child restraints	SC has primary safety-belt enforcement — officers may stop you solely for an unbelted occupant. Rear-facing under age 2; forward-facing from 2 until outgrown; booster from age 4; adult belt at age 8 OR 57 in. Children 7 and younger in back seat. Never place a rear-facing seat in front of an active airbag (4-5 to 4-7).

💡

Headlight Rules That Are Tested

TESTED

When to use headlights: Turn on your headlights whenever visibility is reduced — rainy, snowy, or foggy days, and at dusk or dawn. Use low beams in these conditions (8-8).

High beams — when to use: Use high beams whenever there are no oncoming vehicles. High beams let you see twice as far as low beams (11-1).

Dim high beams: Within 500 ft of an oncoming vehicle, and use low beams when following within 200 ft of another vehicle. Always use low beams in fog, rain, or snow — high beams cause glare (11-1, 11-2).

Oncoming high beams blinding you: Glance toward the right side of the road to avoid being distracted or momentarily blinded — do not look directly into the headlights (11-1, 11-2).

Night driving — add following distance: Add at least 1 extra second of following distance at night, and 2+ additional seconds on unfamiliar roadways (11-2).

⚡

Before the Test — What to Do

PREPARATION

Take the SCDMV 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, distances, suspension periods, speed limits. These are direct exam fodder.

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

Bring required documents: Proof of U.S. citizenship or lawful presence, proof of identity, date and place of birth, Social Security number, two proofs of SC address (see SCDMV form MV-93). Applicants under 18 need the Consent for Minor form (SCDMV Form 447-CM) signed by parent/guardian. Bring glasses or contacts if you wear them (1-3, 1-9).

🧠

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. South Carolina tests reward safe, defensive driving choices.

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

"All of the above" is very often the correct answer on 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."

Refusing a BAC test costs your license. Under SC's implied consent law, refusing a breath, blood, or urine test = immediate loss of driving privileges for at least 6 months (3-7, 3-8).

The real SCDMV knowledge test: 25 multiple-choice questions, 80% passing (20 correct of 25 = 5 allowed wrong), no time limit. Road signs are included in the same 25-question test — they are not separate.
