New Jersey Permit Test Cheat Sheet
A condensed, skimmable recap of the rules most worth knowing cold before your exam — distilled from our full New Jersey practice question bank. This isn't a replacement for the NJ Driver Manual; confirm anything time-sensitive with NJ MVC.
New Jersey Licensing & Law
- New Jersey's graduated licensing rules apply to any first-time applicant under 21, not just teenagers — a 19- or 20-year-old getting a first license still goes through the same permit and probationary stages as a 16-year-old.
- Kyleigh's Law requires permit and probationary drivers under 21 to display small red reflective decals on both license plates; New Jersey is the only U.S. state with this requirement, and skipping it carries a $100 fine.
- A special learner's permit is available at 16 with driver-education enrollment and 6 hours of behind-the-wheel instruction; an examination permit lets 17+ applicants skip driving school and log hours with a parent instead.
- The knowledge test — 50 questions, 80% to pass — is administered in person only, with no online option, but is offered in 13 languages.
- A probationary license upgrades to a basic license online after one year of unsupervised driving.
GDL Restrictions
- No driving between 11:01 p.m. and 5:00 a.m. for permit and probationary holders under 21, with limited work or religious-obligation exceptions.
- Only one additional passenger allowed beyond immediate family, unless a parent or guardian is also in the vehicle.
- GDL drivers may not use a hand-held or hands-free device at all — stricter than the hands-free-permitted rule for fully licensed adults.
- A minimum of 50 supervised driving hours, including 10 at night, must be logged before the road test.
DUI, Alcohol & Drugs
- New Jersey's zero-tolerance law for drivers under 21 uses a 0.01% BAC threshold — essentially any detectable trace of alcohol, stricter than the 0.02% figure many other states use.
- A BAC of 0.01% to 0.07% for an under-21 driver brings 30 to 90 days of suspension plus community service and a safety program; 0.08% or higher brings the standard adult penalties.
- Alcohol degrades judgment, reaction time, coordination, and vision — all necessary for safe driving, even below the legal limit.
Right-of-Way
- With no signs or signals controlling an intersection, yield to whoever approaches from your right; arrive at a stop sign at the same moment as another driver and the same rule applies.
- A driver turning left has to let oncoming traffic and crossing pedestrians clear before completing the turn.
- A vehicle already on the roadway has the right-of-way over one entering from a driveway, alley, or parking lot.
- No one can force you to take the right-of-way — yielding whenever it avoids a collision is always the safer move.
Traffic Signals
- A solid red light means a full stop; treat a flashing red exactly like a stop sign.
- A flashing yellow signal means proceed with caution — no full stop is required.
- A green arrow gives a protected turn, since opposing traffic is held on red while it's active.
- If a signal is dark or malfunctioning, treat the intersection as if every approach had its own stop sign.
Traffic Signs
- Shape is a nationwide code: octagon means stop, downward-pointing triangle means yield, diamond means warning, pentagon marks a school zone.
- Color carries meaning too — red for stop/yield/prohibition, orange for construction, yellow for warnings, white for regulatory rules.
- A red circle with a diagonal slash is the standard national way to say an action isn't allowed.
- "Do Not Enter" and "Wrong Way" signs face oncoming traffic that would otherwise travel against the correct direction.
Lane Markings & Usage
- Yellow lines separate opposing directions of traffic; white lines separate lanes traveling the same direction.
- A broken line permits a lane change when safe; a solid line discourages crossing, typically near intersections or exits.
- A two-way left-turn lane lets vehicles from either direction merge briefly to finish a left turn.
Turning
- Signal well ahead of the turn itself, so other drivers actually have time to react.
- A right turn on red is generally legal after a complete stop and yielding, unless a posted sign says otherwise.
- Finish a left turn in the lane nearest the center line of the road you're entering.
- A safe U-turn always needs a clear view of traffic in both directions.
Passing
- A solid yellow line on your side blocks passing from your direction; a double solid yellow blocks it for both directions.
- The posted speed limit still applies mid-pass.
- Wait to see the vehicle you passed in your rearview mirror before merging back into its lane.
Following Distance
- Hold at least a 3-second gap in normal conditions, and stretch that further in rain, fog, or heavy traffic.
- Tailgating is a leading cause of rear-end crashes.
Freeway Driving
- Use the acceleration lane to match highway speed before merging.
- Signal and move into the exit lane well ahead of your exit; if you miss it, keep going safely to the next one.
- The rightmost lanes generally carry slower traffic and vehicles entering or leaving.
Roundabouts
- Traffic circulates counterclockwise, and vehicles already inside have the right-of-way over ones entering.
- Signal right just before your exit; missing it just means going around again.
Railroad Crossings
- Slow down, look both ways, and listen before crossing, even where there are no gates or lights.
- Never stop on the tracks, and never drive around a lowered gate.
Pedestrians & Crosswalks
- Every intersection is a legal crosswalk, marked or not, and pedestrians there have the right-of-way.
- Passing a car stopped for a pedestrian creates a "multiple threat" hazard.
- A white cane or guide dog marks a visually impaired pedestrian — stop and yield without exception.
School Zones
- Children move less predictably than adult pedestrians, so slow down and follow any crossing guard's directions.
- A reduced school-zone speed limit only applies during its posted hours.
Bicycles
- Cyclists are generally treated as vehicle operators, with the same rights and duty to follow traffic law.
- Give a cyclist at least 3 feet of clearance when passing.
- Check for an approaching cyclist before opening a car door to avoid a "dooring" collision.
Sharing the Road with Large Vehicles
- If you can't see a truck driver's mirrors, assume they can't see you either.
- Trucks and buses often swing wide before turning — never try to squeeze into that gap on their turning side.
- Trucks need much more distance to stop than a car does.
Move Over & Emergency Vehicles
- Move over a lane away from a stopped emergency vehicle when safe, or slow down noticeably if you can't change lanes.
- Pull right and stop for an approaching emergency vehicle unless directed otherwise.
Parking
- Parking within 15 feet of a fire hydrant is generally off-limits.
- Turn your wheels away from the curb parking uphill with no curb, and toward the curb parking downhill facing one.
Defensive Driving
- Defensive driving means actively expecting the other driver's mistake and positioning yourself to respond safely.
- A space cushion around your vehicle buys you room and time to react to a hazard.
- Scan further down the road, not just the car directly ahead, for earlier warning.
Weather Conditions
- Use low beams in fog — high beams bounce off water droplets and throw glare back at you.
- If you start hydroplaning, ease off the gas instead of braking or steering sharply.
- The first rain after a dry stretch is often the slickest.
Night Driving
- Switch to low beams within roughly 500 feet of an oncoming vehicle so you don't blind the other driver.
- Look toward the right edge of your lane rather than straight into oncoming headlights.
Fatigue & Drowsy Driving
- Yawning, heavy eyelids, and drifting out of your lane are early signs your body is losing the fight to stay alert.
- Actual sleep or switching drivers is the only real fix.
Vehicle Equipment
- Headlights are generally required starting a half hour after sunset through a half hour before sunrise.
- Worn tire tread loses grip on wet roads much faster.
Backing Up & Reversing
- Mirrors don't show everything behind a vehicle — look through the rear window directly too.
- A vehicle backing out owes the yield to traffic already using that path.
Work Zones
- Fines commonly double for violations inside a posted, active construction or maintenance zone.
- A flagger's directions override the standard signs and signals in that area.
Insurance & Registration
- Drivers must be ready to present a license, registration, and proof of insurance at any traffic stop.
Hand Signals
- A straight, horizontal left arm signals a left turn if your turn signals aren't working.
- A left arm bent upward at the elbow signals a right turn.
After a Collision
- Check for injuries and call 911 before dealing with any paperwork.
- Stop and exchange information with everyone involved — leaving without doing so is a hit-and-run.
Seatbelts & Child Safety
- New Jersey law requires a seatbelt for the driver and every passenger, front seat and back.
School Buses
- Traffic in both directions on an undivided road must stop for a school bus with flashing red lights, and wait until the lights stop flashing.
Speed Limits
- The basic speed law requires a safe speed for conditions, which can be lower than the posted limit.
