This free New Jersey DMV study guide teaches every topic on the knowledge test, drawn entirely from the official New Jersey Driver Manual.[1]New Jersey’s license office is the Motor Vehicle Commission (MVC)— many people search for the “New Jersey DMV,” but the agency is the MVC.[6]
The New Jersey written test is 50 multiple-choice questions, and you need 40 correct (80%) to pass.[2]Everything here is New Jersey-specific: the state’s DWI tiers, the , the unique path with red decals, and the points-to-surcharge ladder. It’s interactive, not a wall of text — every area has a checkpoint quiz, hover-able glossary terms, and worked scenarios.
Read this guide area by area, test yourself at each checkpoint, then round out your free prep with our New Jersey practice test and flashcards. Studying for a different state? Start with our general DMV practice test.

The New Jersey Motor Vehicle Commission (MVC) written knowledge test draws every question from the New Jersey Driver Manual. The mix below shows roughly how this study guide groups those 50 questions.
You can miss up to 10 and still pass. Every question comes straight from the official New Jersey Driver Manual — there is no math and no trick wording.
The questions are evenly approachable — there is no math and no trick wording. Spend your time across all four areas, but know that signs and rules of the roadmake up the bulk of the test, and that New Jersey’s DWI and GDL rules are the ones most likely to trip up out-of-state drivers:
The New Jersey test draws every question from the manual, so the mix above is an approximation to guide your study time — the actual form varies.[2] This guide teaches all four areas as four study modules.
1 · Traffic Signs, Signals & Pavement Markings
About 16 of 50 questions. The New Jersey test leans heavily on recognizing signs by their shape and color and knowing what signals and pavement markings mean — pure recall from the manual.[1]
Sign Shapes & Colors
You can often identify a sign from its shape and color alone, before you read a word. Memorize these — they are some of the easiest points on the test:
| Shape / color | Meaning |
|---|---|
| Octagon (8 sides), red | STOP — always a full stop |
| Triangle (point down), red & white | YIELD — give the right-of-way |
| Diamond, yellow | General warning (curve, hill, merge ahead) |
| Diamond, orange | Construction / work zone ahead |
| Diamond, fluorescent yellow-green | Pedestrian, school, or bicycle crossing |
| Pentagon (5 sides) | School zone or school crossing |
| Pennant (sideways triangle), yellow | No-passing zone (on your left) |
| Rectangle, white | Regulatory (speed limit, one way, lane use) |
Traffic Signals
Beyond steady red, yellow, and green, the New Jersey test checks the meaning of flashing and special signals:
| Signal | What to do |
|---|---|
| Steady red | Stop and stay stopped until green; a right turn on red is allowed after stopping unless a sign prohibits it |
| Steady yellow | The light is about to turn red — stop if you safely can |
| Flashing red | Same as a STOP sign: stop, yield, then go when safe |
| Flashing yellow | Caution — slow down and proceed carefully |
| Red arrow | Stop; no turn in that direction until the arrow turns green |
| Dark signal (power out) | Treat the intersection as an all-way stop |
Pavement Markings
Line color and pattern tell you where you can drive and pass. The single most-tested rule: yellow separates opposing traffic; white separates same-direction traffic.
| Marking | Meaning |
|---|---|
| Solid yellow on your side | No passing — do not cross to pass |
| Broken (dashed) yellow | Passing allowed when it is safe |
| Double solid yellow | No passing in either direction |
| Solid white line | Discourages lane changes; stay in your lane |
| Broken white line | Lane change allowed when safe |
| Yellow diagonal stripes / gore area | A painted buffer — do not drive on or cross it |
Checkpoint · Area 1 · Signs, Signals & Markings
Question 1 of 10
What does a flashing red traffic signal mean for a New Jersey driver?
2 · Rules of the Road & Right-of-Way
About 18 of 50 questions — the largest area. Speed limits, who goes first, the keep-right law, and how New Jersey licenses new drivers. is something you yield, never take.[1]
New Jersey Speed Limits
When no sign is posted, New Jersey’s statutory limits apply, and the always requires a safe speed for conditions:
| Location | Limit (unless posted otherwise) |
|---|---|
| School zone, business or residential district | 25 mph |
| Most other roadways (none posted) | 50 mph |
| Certain state highways | 55 mph (where posted) |
| Certain state highways / interstates | 65 mph (only where specifically posted) |
Right-of-Way & Intersections
At a , the first vehicle to stop goes first; if two arrive together, the driver on the left yields to the driver on the right. A driver turning left always yields to oncoming traffic going straight.
| Situation | Who yields |
|---|---|
| Four-way stop, two arrive together | Driver on the left yields to driver on the right |
| Turning left at an intersection | You yield to oncoming traffic going straight |
| Entering a roundabout | You yield to traffic already circulating and to pedestrians |
| Pedestrian in a marked crosswalk | Stop and stay stopped for the pedestrian |
| Emergency vehicle with lights/siren | Pull to the right edge and stop until it passes |
| Merging at a yield sign | You yield; merge smoothly only when a safe gap exists |
Keep Right, Passing & Roundabouts
New Jersey’s law means you drive in the right-hand lane on a multi-lane highway and use the left lane only to pass — then return to the right. A right turn on red is allowed after a complete stop unless a sign is posted.
At a roundabout, yield to traffic already circulating and to pedestrians, enter to the right when there is a gap, keep going counter-clockwise, and signal before your exit. If an emergency vehicle approaches while you are inside, continue to your exit, then pull over.
Licensing & the Graduated Driver License
New Jersey phases teens in through the system — a high-yield topic for the test — and uniquely requires the red decals throughout.[3]
New Jersey's GDL phases new drivers through three stages — Special Learner Permit → Examination Permit → Probationary License — before a full Basic License. It is one of the few states whose GDL restrictions run all the way to age 21.
- Age 16 — Special Learner PermitA 16-year-old who enrolls in an approved behind-the-wheel driver-education course may get a Special Learner Permit. Practice must be supervised, and the red decal and GDL restrictions apply.
- Age 17 — Examination PermitAt 17, a teen who did not take the special learner course (or who is continuing) gets an Examination Permit after passing the knowledge test and vision screening, then practices with a supervising driver.
- Hold the permit — at least 6 months (under 21)A permit holder under 21 must practice under supervision for a minimum of 6 months, accident- and offense-free, before taking the road test.
- Probationary (provisional) LicenseAfter passing the road test, the driver gets a Probationary License and must hold it for a minimum of 12 months. The red decals and GDL passenger/curfew rules continue.
- Basic (unrestricted) LicenseAfter the probationary period — and once GDL restrictions end at age 21 — the driver receives a Basic Driver License with no decal, curfew, or passenger limits.
GDL permit and probationary drivers may not drive between 11:01 p.m. and 5:00 a.m., may carry only one passenger (plus dependents), and must use no phone at all. Confirm current rules with New Jersey MVC.
Kyleigh’s Law requires every GDL driver under 21 (Special Learner, Examination Permit, and Probationary License holders) to display a removable red reflectorized decal on the upper-left corner of the front and rear license plates.
It lets police see at a glance that the GDL curfew and passenger rules apply. Failing to display the decals is a $100 fine.
The decals are bought from the MVC and must be displayed whenever a GDL driver is behind the wheel. They come off when full (Basic) driving privileges begin.
Checkpoint · Area 2 · Rules of the Road & Right-of-Way
Question 1 of 10
On most New Jersey roadways where no speed limit is posted, what is the maximum legal speed?
3 · Safe & Defensive Driving
About 10 of 50 questions.Following distance, visual scanning, and — most important for the New Jersey test — the state’s impaired-driving and distracted-driving laws.[1]
Following Distance & Visual Search
Keep a safe gap with the : stay at least three seconds behind the vehicle ahead, and increase it in rain, fog, or behind a motorcycle. Scan well down the road, check your mirrors every few seconds, and turn your head to check blind spots before you change lanes. Remember New Jersey’s .
New Jersey DWI & BAC Limits
New Jersey calls impaired driving — Driving While Intoxicated. The adult legal limit is 0.08% (0.04% commercial), with a higher-penalty tier at 0.10% or more. Drivers under 21 face at 0.01%:
In New Jersey the offense is called DWI (Driving While Intoxicated). The adult legal limit is 0.08% (0.04% for a commercial driver), and drivers under 21 face a 0.01% zero-tolerance limit. By driving in New Jersey you give implied consent to a breath test; refusing it carries its own penalties.
- Under 21 — Zero tolerance, BAC 0.01% or higherNew Jersey's zero-tolerance law: a driver under 21 with a BAC of 0.01% or more loses driving privileges for 30 to 90 days, performs community service, and must complete an Intoxicated Driver Resource Center program.
- Standard DWI — BAC 0.08% to under 0.10% (age 21+)A first offense at 0.08%–0.099% brings a fine, an Intoxicated Driver Resource Center program, and an ignition interlock device during and after a short license forfeiture. New Jersey calls the offense DWI (Driving While Intoxicated).
- High-tier DWI — BAC 0.10% or higher (age 21+)A first offense at 0.10% or above carries higher fines, a longer ignition-interlock requirement, possible jail, and steeper insurance surcharges than the standard tier.
New Jersey adds an annual insurance surcharge after a DWI on top of court penalties. Exact amounts change — always confirm current penalties with the court or MVC.
By driving in New Jersey you give to a breath test; refusing one carries its own penalty on top of the DWI charge. A conviction also requires an and an annual insurance surcharge.
Hands-Free Law & Distracted Driving
New Jersey makes it illegal to hold or support a phone while driving — no texting or handheld calls. It is a primary offense, so an officer can pull you over for that alone, and the first-offense fine is at least $200. GDL drivers may not use any phone, even hands-free.
Points, Surcharges & Suspension
New Jersey assigns to moving violations and acts on your totals — a at 6 points, suspension at 12:
- Reckless driving5 points
- Improper passing / passing in a no-pass zone4 points
- Tailgating (following too closely)5 points
- Speeding 15–29 mph over4 points
- Failure to yield to a pedestrian2 points
- Most common moving violations2 points
New Jersey counts points on your current record and acts on the totals above. Exact point values are set by New Jersey law — verify current figures with MVC.
Checkpoint · Area 3 · Safe & Defensive Driving
Question 1 of 10
In New Jersey, an adult driver age 21 or older is considered legally intoxicated (DWI) at what blood alcohol concentration (BAC)?
4 · Sharing the Road & Special Situations
About 6 of 50 questions. Emergency vehicles, school buses, vulnerable road users, and the bad-weather hazards the New Jersey manual emphasizes.[1]
The Move Over Law & Emergency Vehicles
New Jersey’s protects roadside responders and workers. When an emergency vehicle approaches with lights and siren, pull to the right edge and stop until it passes.
Violating New Jersey’s Move Over Law carries a fine of not less than $100 and not more than $500.
School Buses & Vulnerable Road Users
When a New Jersey school bus shows flashing red lights, drivers in both directions must stop at least 25 feet away on an undivided road. On a divided highway, traffic moving the opposite way may proceed at no more than 10 mph. A painted center line is not a divider.
- 1. Red lights flashingStop at least 25 feet away in both directions on an undivided road.
- 2. Wait — do not moveStay stopped while children load or cross. A painted line is not a barrier.
- 3. Dual highway exceptionOn a divided highway, traffic moving the opposite way may proceed at no more than 10 mph past the bus. If unsure, stop.
Passing a stopped New Jersey school bus with red lights flashing is a serious violation. 2026 rules from the New Jersey Driver Manual.
| Road user | What New Jersey drivers must do |
|---|---|
| Pedestrian in a crosswalk | Stop and stay stopped; never pass a vehicle stopped for a pedestrian |
| Bicyclist | Treat them as a vehicle; allow safe passing distance |
| Motorcyclist | Allow extra following distance; check blind spots — they're easy to miss |
| Large truck turning right | It may swing left first; never squeeze up the right side |
| School bus (flashing red) | Stop both directions on undivided roads, at least 25 ft away |
Skids, Hydroplaning & Bad Weather
New Jersey’s mix of rain, snow, and fog makes weather handling a tested topic. The manual stresses smooth inputs and slower speeds when traction is poor.
Seat Belts & Child Restraints
New Jersey requires the driver and front-seat passengers to wear seat belts (a primary offense), and children to be restrained by age and size in the rear seat:
| Age / size | Requirement |
|---|---|
| Under age 2 and under 30 lb | Rear-facing seat with a 5-point harness, in the rear seat |
| Under age 4 and under 40 lb | Forward-facing seat with a 5-point harness, in the rear seat |
| Until age 8 or 57 inches tall | Booster seat (then a regular seat belt) |
| Driver & front-seat passengers | Seat belt required — a primary offense |
Checkpoint · Area 4 · Sharing the Road & Special Situations
Question 1 of 10
Under New Jersey's Move Over Law, what must a driver do when approaching a stopped emergency, tow, or highway maintenance vehicle displaying flashing lights?
How to Use This Study Guide

New Jersey DMV Glossary
Quick definitions for the terms you’ll see most across the New Jersey MVC knowledge test:
- BAC
- Blood alcohol concentration. In New Jersey the adult legal limit is 0.08% (0.04% commercial, 0.01% under 21). Driving at or above your limit is the offense New Jersey calls DWI.
- Basic Driver License
- New Jersey's standard, unrestricted operator license for a passenger vehicle, issued after a driver completes the Graduated Driver License (GDL) program.
- Basic speed law
- New Jersey's rule that you must always drive at a speed that is reasonable and safe for current conditions — even when you are below the posted limit.
- DWI
- Driving While Intoxicated — New Jersey's term for impaired driving. The adult limit is a BAC of 0.08% (0.04% commercial), with a higher-penalty tier at 0.10% or more.
- Examination Permit
- A New Jersey GDL permit for a driver at least 17 (or 16 continuing from a learner course) after passing the knowledge test and vision screening, used to practice with a supervising driver.
- Four-way stop
- An all-way-stop intersection. The first vehicle to stop goes first; if two arrive together, the driver on the left yields to the driver on the right.
- Graduated Driver License (GDL)
- New Jersey's staged licensing system — Special Learner Permit, Examination Permit, then Probationary License — that eases new drivers into full privileges to reduce crashes. Restrictions run to age 21.
- Ignition interlock device
- A breath-test device wired to a vehicle's ignition that prevents it from starting if alcohol is detected. New Jersey requires one after a DWI conviction.
- Implied consent
- By driving in New Jersey you agree to take a breath test if lawfully arrested for DWI. Refusing causes a separate penalty in addition to the DWI charge.
- Keep Right
- New Jersey's rule that you drive in the right-hand lane and use the left lane only to pass slower traffic, returning to the right after the pass.
- Kyleigh's Law
- The New Jersey law requiring GDL drivers under 21 to display a red reflectorized decal on the upper-left corner of the front and rear license plates. Failing to display it is a $100 fine.
- Move Over Law
- New Jersey's law requiring drivers to move one lane away from a stopped emergency or service vehicle with flashing lights, or to slow below the posted speed if they cannot move over safely.
- New Jersey MVC
- The New Jersey Motor Vehicle Commission, the state agency that issues driver licenses and permits and administers the written knowledge test. New Jersey calls it the MVC, not the DMV.
- No Turn on Red
- A posted sign that overrides New Jersey's default allowance of a right turn on red. Where it is posted, you may not turn on the red signal.
- Points
- Demerit values New Jersey assigns to moving violations. 6 or more in 3 years brings an insurance surcharge; 12 or more leads to a license suspension.
- Probationary License
- New Jersey's provisional license, earned after the road test, held a minimum of 12 months with the red decals and GDL passenger and curfew restrictions still in effect.
- Right-of-way
- The right of one road user to proceed first. In New Jersey, right-of-way is something you yield (give) — never something you take. When in doubt, yield.
- School zone
- An area near a school with a reduced speed limit (often shown by flashing beacons) that applies when children are present.
- Solid yellow line
- A center line separating opposing traffic. A solid yellow line on your side means no passing; a broken yellow line means passing is allowed when safe.
- Special Learner Permit
- The first New Jersey GDL stage, available at 16 to a teen enrolled in an approved behind-the-wheel driver-education course. Driving must be supervised and the red decals apply.
- Surcharge
- An annual fee New Jersey adds for 3 years once a driver reaches 6 or more points in 3 years — 25 for each point above six.
- Three-second rule
- A following-distance method: stay at least three seconds behind the vehicle ahead (more in rain, fog, or behind a motorcycle) so you have time to react.
- Wipers-on, lights-on rule
- New Jersey's law requiring headlights whenever your windshield wipers are in continuous use because of rain, snow, or fog — even in daytime.
- Zero tolerance
- New Jersey's rule that a driver under 21 may not drive with a BAC of 0.01% or higher — essentially any measurable alcohol is a violation.

New Jersey DMV Study Guide FAQ
The New Jersey MVC knowledge test has 50 multiple-choice questions drawn from the official New Jersey Driver Manual, and you must answer at least 40 correctly — 80% — to pass. The test is given by the New Jersey Motor Vehicle Commission (MVC), which New Jersey calls the MVC, not the DMV.
Every question comes from the New Jersey Driver Manual and falls into four areas: traffic signs, signals, and pavement markings; rules of the road and right-of-way; safe and defensive driving (including New Jersey's DWI laws); and sharing the road and special situations like school buses and bad weather.
It is illegal for an adult 21 or older to drive in New Jersey with a BAC of 0.08% or higher, or 0.04% for a commercial driver. New Jersey calls the offense DWI and adds a higher-penalty tier at 0.10% or more. Drivers under 21 face a zero-tolerance limit of 0.01%.
When you approach a stopped emergency or service vehicle showing flashing lights, New Jersey's Move Over Law requires you to change into a lane not next to it if you safely can. If you cannot move over safely, you must slow below the posted speed and be ready to stop. The fine is $100 to $500.
Kyleigh's Law requires every New Jersey GDL driver under 21 to display a red reflectorized decal on the upper-left corner of the front and rear license plates, so police can see the curfew and passenger rules apply. Failing to display the decals is a $100 fine.
New Jersey's Graduated Driver License runs through three stages: Special Learner Permit (16, with a driver-ed course), Examination Permit (17, or 16 continuing), then Probationary License after the road test, held at least 12 months. GDL drivers can't drive 11:01 p.m.–5 a.m., carry only one passenger, use no phone, and must show the red decals until age 21.
New Jersey assigns points to moving violations — for example 5 for reckless driving. Reaching 6 or more points in 3 years brings an annual insurance surcharge of $150 plus $25 per point above six, and reaching 12 or more points leads to a license suspension. A clean year removes 3 points.
New Jersey requires headlights from a half hour after sunset to a half hour before sunrise, and any time your windshield wipers are in continuous use because of rain, snow, or fog. This 'wipers-on, lights-on' rule is specific to New Jersey and easy to forget in daytime rain.
Work through the four content areas — signs and markings, rules of the road, safe driving, and sharing the road — taking the checkpoint quiz after each. Then drill weak areas with our free New Jersey practice test and flashcards, and reread the official manual before test day.
