📖 Delaware DMV Study Guide

Everything important from the Delaware Driver Manual (July 2025) — organized for the exam

⭐

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

Speed Limits

HIGH FREQUENCY

25 mph

Default speed limit in business and residential districts in Delaware. Always obey posted limits (p. 91).

20 mph

School zone speed limit when children are present or as posted. Fines and points are doubled for violations in school zones (p. 91).

50 / 55 / 65 mph

Two-lane highways: 50 mph. Divided highways with 4+ lanes and controlled-access roads: 55 mph. Route 1 and I-495: 65 mph (p. 91).

Posted

Speed limits are posted for ideal conditions. Drivers must reduce speed for rain, ice, heavy traffic, or any condition that makes the posted speed unsafe.

3 sec

Three-Second Rule — count the seconds between when the vehicle ahead passes a fixed point and when you reach it. Less than three seconds means you are following too closely (p. 125).

4 sec

Increase to a 4-second count above 40 mph behind motorcycles, in heavy rain, snow, fog, or at night. On packed snow or ice, double the distance (p. 98, 124).

📏

Critical Distances & Clearances

HIGH FREQUENCY

15 ft

Do not park within 15 feet of a fire hydrant in Delaware (p. 89-91).

20 ft

Do not park within 20 feet of a crosswalk at an intersection or 20 feet from the entrance of a fire station (p. 89-91).

30 ft

Do not park within 30 feet of a stop sign, yield sign, flashing signal, or other traffic-control device (p. 89-91).

50 ft

Do not park within 50 feet of a railroad crossing in Delaware (p. 89-91).

12 in

Parallel park — your vehicle must be no more than 12 inches from the curb when finished (p. 89-91).

Both headlights

After passing, return to your lane only when you can see BOTH headlights of the passed vehicle in your rearview mirror.

500 / 200 ft

Dim high beams within 500 feet of an oncoming vehicle and within 200 feet when following another vehicle (p. 59-61).

1,000 ft

Headlights are required when windshield wipers are on or when visibility is less than 1,000 feet. Use low beams in fog, rain, or snow (p. 59-61).

300 ft

Signal continuously for at least the last 300 feet before any turn or lane change in Delaware (p. 59-61).

All occupants

Delaware seat-belt law is primary enforcement — all front-seat occupants and all passengers under 16 in any seat must be restrained. Officers may stop a vehicle for a seat-belt violation alone (p. 107).

3 ft

When passing a bicyclist on a Delaware road, you must leave a minimum of 3 feet of clearance at all times (p. 79, 94).

Stop

Stop in BOTH directions for a school bus with red lights flashing — UNLESS you are on the opposite side of a 4+ lane road, in which case you may proceed slowly with caution (p. 79, 87-88).

🍺

DUI & Alcohol Numbers

ALWAYS ON TEST

0.08%

Legal BAC limit for drivers 21 and older. You can be arrested for DUI at 0.08% or above — or for any impairment from alcohol or drugs (p. 49, 53-57).

0.02%

Zero Tolerance for drivers under 21 — the per-se BAC limit is 0.02%. License revocation and additional consequences apply for violations (p. 49, 53-57).

1st DUI

$500–$1,500 fine plus court charges, up to 12 months in jail, and a 12-month DMV license revocation (BAC under .15). Penalties escalate to 18 months (BAC .15-.19) or 24 months (BAC .20+ or refusal) (p. 49, 53-57).

Refusal

Under Implied Consent, by driving on Delaware roads you agreed to submit to a breath, blood, or urine test if a peace officer requests one after a DUI arrest. Refusal triggers a 12-month license revocation on a 1st offense — separate from any DUI conviction (p. 49, 53-57).

$50 / $200

License reinstatement fee: $50 after a suspension; $200 after a revocation in Delaware (p. 14).

🎓

Teen / GDL Numbers

ON EXAM

Age 16

Minimum age for a Delaware Level-1 Learner Permit (max age 18, or 16-22 with an Individualized Education Program). Must be held at least 6 months. Supervisor must be 25+ with a Class D license held at least 5 years (p. 27-29).

Age 16½+

After 6 months on the Level-1 Permit (with 50 supervised hours including 10 at night), you may obtain a Level-2 / Class D Restricted License with no traffic, alcohol, or drug offenses in the prior 6 months (p. 27-29).

10 PM – 6 AM

During the first 6 months on the Level-1 Permit, no unsupervised driving 10 PM to 6 AM. After 6 months on the restricted license, unsupervised driving allowed only 6 AM–10 PM. Limited exceptions: church, work, or school activities (p. 27-29).

1 passenger

Level-1 Permit holders may have only one passenger in the front seat (the supervisor) and may not drive with anyone in the vehicle without the licensed adult supervisor (p. 27-29).

6 months / 50 hrs

Hold the Level-1 Permit at least 6 consecutive months and log 50 hours of supervised driving — 10 of those at night — before advancing to the Class D Restricted License (p. 27-29).

Age 17+

Full unrestricted Class D license is issued after Restricted License period ends. Class D fee: $40 for 8 years. Late renewal $10; replacement license $20 (p. 14).

⏱️

Following Distance & Time Rules

ON EXAM

3 sec

Three-Second Rule — count the seconds between when the vehicle ahead passes a fixed point and when you reach it. Less than three seconds means you are following too closely (p. 125).

4 sec

Increase to 4+ seconds behind motorcycles above 40 mph, on wet/icy roads, in poor weather, in construction zones, or at night. On packed snow, double the distance (p. 98, 124).

200 / 400 ft

At 30 mph it takes about 200 feet to perceive, react, and stop. At 50 mph it takes about 400 feet (about a city block). Stopping distance grows with speed and is affected by reaction time, pavement, tires, and brakes (p. 124).

No hand-held

Hand-held cell phone use while driving is banned for adults in Delaware. Hands-free use is permitted for adults; ALL cell phone use (even hands-free) is banned for permit and Class D Restricted License holders. Texting while driving is prohibited for everyone (p. 27-29).

🚦

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 or work-zone ahead. Fines are doubled in Delaware work zones, and aggressive driving in a work zone carries a $100-$300 fine for a 1st offense plus a mandatory driver-improvement course (p. 46-47).
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 DMV 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 / passing stopped emergency or service vehicles: Delaware's Move Over law requires drivers to change lanes away from any stopped emergency, tow, utility, postal, or sanitation vehicle displaying flashing lights. If you cannot safely change lanes, slow to a reasonable and prudent speed below the posted limit. Violations carry significant fines and points (p. 79).

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 — give a continuous turn signal for at least 300 feet before turning or changing lanes in Delaware (p. 59-61).

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 DMV knowledge test. Know the BAC levels, implied consent law, and penalties. Delaware 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+)	1st DUI: $500–$1,500 fine plus court charges, up to 12 months in jail, and a 12-month DMV license revocation (BAC under .15). Penalties escalate to 18 months (BAC .15-.19) or 24 months (BAC .20+ or refusal) (p. 49, 53-57).
Impairment below the legal BAC limit	You can still be arrested for DUI in Delaware at any BAC if alcohol or drugs (prescription, OTC, or controlled) impair your ability to drive. Judgment is the first ability affected by alcohol (p. 49, 53-57).
Test refusal (implied consent)	By driving on Delaware roads you have agreed to submit to a chemical test (breath, blood, or urine) when requested by an officer after a DUI arrest. Refusal triggers a 12-month license revocation on the 1st offense — separate from any DUI conviction (p. 49, 53-57).
BAC — under 21 (Zero Tolerance)	The per-se BAC limit for drivers under 21 is 0.02%. Convictions affect the driver license and can extend GDL restrictions. Buying or consuming alcohol under 21 is also illegal in Delaware (p. 49, 53-57).
CDL / commercial driver BAC	Commercial drivers operating a commercial motor vehicle are held to the federal 0.04% BAC limit (p. 49, 53-57).
DUI — causing death or injury	A DUI causing serious bodily injury or death is a felony in Delaware with enhanced fines, mandatory minimum jail time, and long-term license revocation. Habitual offenders may face up to a 5-year license revocation (p. 43-44).

💡

Critical DUI Facts to Remember

TESTED

Implied consent: By driving on Delaware roads, you consent in advance to a breath, blood, or urine test if a peace officer asks for one after a DUI arrest. Refusal triggers a 12-month license revocation on a 1st offense. Reinstatement after revocation costs $200 (p. 49, 53-57).

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 by alcohol — and you can be arrested for DUI in Delaware at any BAC when alcohol or drugs impair your ability to drive (p. 49, 53-57).

Under-21 Zero Tolerance: The per-se BAC limit for Delaware drivers under 21 is 0.02% — well below the adult 0.08% threshold. Buying or consuming alcohol under 21 is also illegal in Delaware. Convictions can extend GDL restrictions and trigger separate license actions (p. 49, 53-57).

Mixing drugs and alcohol: Never drink alcohol while taking medications or other drugs. Combinations may multiply effects, reduce driving ability, and cause serious health problems or death. Having a prescription is not a defense if the medication impairs driving.

Cell phone law: Delaware bans hand-held cell phone use for adult drivers; hands-free use is permitted. ALL cell phone use (even hands-free) is banned for permit and Class D Restricted License holders. Texting while driving is prohibited for everyone, regardless of age (p. 27-29).

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. Stop in BOTH directions when a school bus shows flashing red lights — UNLESS you are on the opposite side of a road with 4 or more lanes, in which case you may proceed slowly with caution. Yellow flashing lights warn you about 10 seconds before red (p. 79, 87-88).

🚌

School Bus Stopping Rules

HEAVILY TESTED

Two-lane / undivided road: Traffic in BOTH directions must stop when a school bus shows flashing red lights on an undivided road in Delaware (p. 79, 87-88).

Divided-highway exception: If you are traveling on the opposite side of a road with 4 or more lanes, you do not have to stop — but you must proceed slowly and watch for children. Same-direction traffic must always stop, regardless of road type (p. 79, 87-88).

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

After the bus stops: Remain stopped until the bus resumes motion or deactivates its warning signals AND all loading/unloading passengers have cleared the roadway. Then proceed slowly, watching carefully for children near the roadway.

When may you proceed: Only when the red lights STOP flashing, the stop arm retracts, and the bus begins moving. It is unlawful to pass a stopped school bus while it is loading or unloading passengers.

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.

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

Penalty for passing a stopped school bus — 1st conviction: Fine of $115–$230, OR 30–60 days in jail, OR both, plus a 1-month license suspension and 6 points assessed to your driving record. No driving authority is permitted during the 1-month suspension (p. 79, 87-88).

Subsequent / serious offenses: A second offense within 3 years carries a 6-month license suspension. A third offense within 3 years carries a 1-year suspension. Charges escalate sharply if a violation causes injury or death (p. 79, 87-88).

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: Fines are doubled in Delaware work zones. Aggressive driving in a work zone carries a $100-$300 fine for a 1st offense plus a mandatory driver-improvement course. Obey flagger directions and posted reduced speed limits even when no workers are visible (p. 46-47).

"Over-driving your headlights": Headlights are required in Delaware whenever windshield wipers are on or visibility is less than 1,000 feet. Low beams reveal about 100 feet ahead; high beams reveal about 350 feet. Never drive faster than you can stop within the distance lit by your headlights (p. 59-61).

Sight-distance rule for conditions: Pick a stationary object ahead and count your approach time. If you reach the object before the expected count — you are going too fast for the conditions. Slow down.

↔️

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 three seconds — you are following too closely. Slow down and increase the gap. In adverse conditions, increase to 4 or more seconds (p. 125).

💡 When to increase beyond the minimum

Rain, snow, ice, or fog → 4 seconds minimum
Driving at night → increase beyond the minimum
Following a large truck or motorcycle → 4+ seconds
Towing a trailer → 4 seconds minimum
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 a hill or curve where you cannot see ahead; within 100 feet of a bridge, viaduct, tunnel, intersection, or railroad crossing; when oncoming traffic is too close to allow a safe return; on the shoulder; when a school bus is stopped with red lights flashing; or in any zone marked with a solid yellow line on your side, a no-passing pennant, or a "Do Not Pass" sign (p. 79, 83).

→

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	Minimum Clearance
Fire hydrant	15 ft — do not park within 15 ft (p. 89-91)
Stop sign / yield sign / flashing signal / traffic control device	30 ft — do not park within 30 ft of these (p. 89-91)
Pedestrian safety zone	Do not park alongside or opposite a marked safety zone in Delaware (p. 89-91)
Crosswalk at intersection	20 ft — do not park within 20 ft of a crosswalk at an intersection (p. 89-91)
Railroad crossing	50 ft — do not park within 50 ft of a railroad crossing (p. 89-91)
Fire station driveway	20 ft from the entrance of the fire station — never block any portion of a fire-station driveway (p. 89-91)
Driveway entrance (public or private)	Not in front of — always prohibited
Accessible (handicapped) space	Never without valid placard/plate — vehicle may be towed and a fine assessed (p. 89-91)
Inside an intersection or on a crosswalk	Never — always illegal
Bridge, overpass, or tunnel	Never — always prohibited in Delaware (p. 89-91)
No Stopping zone	Never stop here, for any reason
No Parking zone	No parking — may stop to load/unload

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

🎓

Delaware Graduated Driver Licensing (GDL)

ON EXAM

Phase 1 — Level-1 Learner Permit (age 16+)

→

Minimum age: 16 (max 18, or 16-22 with an Individualized Education Program). Applicants must pass vision, knowledge, and signs/signal exams. Drivers under 18 need a parent/guardian consent form and proof of school enrollment (p. 27-29).

→

A parent or guardian who signed the consent may revoke the minor's permit at any time. The Level-1 Permit is valid until the minor advances to a Class D Restricted License or turns 21 (p. 27-29).

→

Supervisor must be at least 25 years old, hold a valid Class D license for at least 5 years, and occupy the front passenger seat next to the permit holder at all times (p. 27-29).

→

Hold the Level-1 Permit at least 6 consecutive months and log 50 hours of supervised driving (10 at night). ALL cell phone use — even hands-free — is banned for permit holders. A violation is treated as driving without a license, carrying a 2-month suspension on a 1st offense (p. 27-29).

Phase 2 — Class D Restricted License (age 16½+)

→

Eligibility: at least 6 consecutive months on the Level-1 Permit, 50 hours of supervised driving (10 at night), no traffic, alcohol, or drug offenses in the prior 6 months, and parent/guardian certification of supervised hours brought to the DMV (p. 27-29).

→

Restrictions: unsupervised driving allowed only 6:00 AM–10:00 PM. Supervised driving (with a licensed adult 25+) is required outside those hours, with limited exceptions for church, work, or school activities. ALL cell phone use (even hands-free) is banned for restricted-license holders (p. 27-29).

→

License fee: Class D 8-year fee is $40. Late renewal $10; replacement $20. The Restricted License auto-converts to a full Class D after the restriction period ends with a clean driving record (p. 14, 27-29).

Full Unrestricted License (age 17+)

→

Standard Class D license valid for 8 years; fee $40. No additional testing required when restrictions auto-expire after the Class D Restricted License period ends with a clean record (p. 14, 27-29).

→

Adult applicants 18+ are not required to complete driver education but must pass vision, knowledge, and road tests. New residents must obtain a Delaware license within 60 days of becoming a Delaware resident; address changes must be reported within 30 days (p. 17).

→

Hand-held cell phone use is banned for all adult drivers in Delaware; hands-free is permitted. Texting while driving is prohibited for everyone, regardless of age. Reinstatement after suspension: $50; after revocation: $200 (p. 14, 27-29).

🛡️

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 (on)	Headlights are required in Delaware whenever windshield wipers are on or when visibility is less than 1,000 feet. Use low beams (not parking lights) in fog, rain, sleet, or snow (p. 59-61).
High beams (dim)	Dim within 500 ft of an oncoming vehicle and within 200 ft when following another vehicle. Always use low beams in fog, heavy rain, sleet, or snow (p. 59-61).
Horn	Audible from at least 200 feet. Use when needed to prevent a crash. Do NOT use to express anger, greet friends, or encourage others to move. Avoid around blind pedestrians and animal-drawn vehicles (p. 59-61).
Turn signals	Signal continuously for at least 300 feet before any turn or lane change. Turn signals must be visible in normal sunlight; do not use them as a "go ahead" courtesy signal to other drivers (p. 59-61).
Tinted windows	Window tint must not obstruct the driver's view. Studded tires are permitted only between October 15 and April 15. Tail lights must be visible from 500 feet; brake lights from 100 feet (p. 59-61).
TVs / video screens visible to driver	Prohibited while vehicle is in motion (navigation is typically excepted — confirm against Delaware manual).
Muffler	Must prevent excessive or unusual noise
Brakes	Vehicles must have working service brakes capable of stopping under control. Parking brake required. Test brakes lightly after driving through deep water to dry them out.
Wipers	Must adequately clean the windshield when used
Tail lights / rear reflector	Tail lights and rear reflectors are required equipment on all vehicles. Keep lenses clean for night-driving visibility.
Tires	Tire condition and tread composition directly affect stopping distance. Proper inflation and good tread are critical.
Hazard lights	For use when parked/stopped in an emergency — not while driving normally
Seat belts & child restraints	Delaware seat-belt law is primary enforcement. All front-seat occupants and all passengers under 16 in any seat must be restrained. Children under 2 AND under 30 lbs must be in a rear-facing car seat. Children under 4 AND under 40 lbs must be in a forward-facing harnessed seat. Children must not ride in the front seat unless they are 12+ OR at least 5 feet 5 inches tall (p. 107).

Headlight Rules That Are Tested

TESTED

Headlights required by Delaware law: Whenever windshield wipers are on, or whenever visibility is less than 1,000 feet. Use low beams in fog, heavy rain, sleet, or snow (p. 59-61).

Parking lights ≠ headlights: Parking lights are for indicating a parked vehicle only. Headlights are required for driving during the hours and conditions above — not parking lights.

Dim high beams: within 500 feet of an oncoming vehicle and within 200 feet when following another vehicle. Always use low beams in fog, heavy rain, sleet, or snow. High beams reveal about 350 feet ahead; low beams about 100 feet (p. 59-61).

Night driving — "drive in your headlights": Never drive faster than you can stop within the distance lit by your headlights. This is called over-driving your headlights and is dangerous.

Before the Test — What to Do

PREPARATION

Take the DMV 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 identity (e.g., U.S. birth certificate or unexpired U.S. passport), proof of your Social Security Number, two proofs of Delaware residency, and proof of lawful presence if not a U.S. citizen. Drivers under 18 need a parent or guardian consent form and proof of school enrollment. Bring glasses or contacts if you wear them. Class D fee: $40 for 8 years (p. 14, 27-29).

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. Delaware 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 — can cost your license. Under Delaware's Implied Consent law, refusing a chemical test (breath, blood, or urine) after a DUI arrest triggers a 12-month license revocation on a 1st offense — separate from any DUI conviction. Refusal can also be used against you at trial (p. 49, 53-57).

The real Delaware DMV knowledge test: Two parts — a Highway Sign and Signal Test plus a Rules of the Road Test. Both are required to pass. After passing the knowledge exam, you may take the road test 10 days later. Road tests are given at DMV offices in Wilmington, Delaware City, Dover, and Georgetown every weekday except Wednesday (p. 39-40).
