New Jersey Driving Laws 2026: Speed Limits, DUI BAC, Turnpike Rules and NJ MVC Road Rules

What are the speed limits in New Jersey when no sign is posted? New Jersey sets 25 mph in school, business, and residential districts, 35 mph in certain low-density business and residential districts, 50 mph on all other roadways, 55 mph on certain state highways and all interstates, and 65 mph on certain state highways where posted. New Jersey applies an under-21 alcohol rule at 0.01% BAC. Refusing a breath test is a motor vehicle violation with separate license, ignition-interlock, and surcharge consequences. Headlights are required when windshield wipers are in use during rain, snow, or ice.

Key test point: New Jersey uses five commonly tested statutory speed categories: 25, 35, 50, 55, and 65 mph, depending on the roadway or district and any posted limit. A 65 mph limit applies only where posted on designated state highways. Fire hydrant clearance is 10 feet in New Jersey. Handheld electronic-device use is a primary offense; motor-vehicle points begin with a third qualifying offense.

5. Passing in New Jersey: Never Pass a Truck on the Right, Signal Before and After

When is it illegal to pass another vehicle in New Jersey, and how close to an intersection can you pass? Passing is one of the most dangerous maneuvers on the road, New Jersey law sets strict distance and visibility rules:

• Only pass on the left, using the oncoming lane, when it is safe and legal.
• Do not pass within 100 feet of an intersection, railroad crossing, bridge, or curve where your view is limited. Look for the No Passing Zone pennant sign.
• The vehicle being passed must not speed up while you are overtaking.
• Return to your lane before coming within 200 feet of oncoming traffic.
• Never pass a stopped school bus with flashing red lights, this applies in both directions on undivided roads.
• You may pass on the right when the vehicle ahead is turning left and there is enough room, or on a roadway with two or more substantially continuous lines of traffic moving in the same direction. Never pass on the shoulder.
• New Jersey Safe Passing Law: When passing a bicyclist, pedestrian, scooter rider, or other protected vulnerable road user, move over one lane when possible or leave at least 4 feet. If 4 feet is not possible, slow to 25 mph or the lower posted speed and be prepared to stop.
• Frozen dessert truck: When its red lights flash and stop arm is extended, stop, yield to anyone crossing, and pass only at no more than 15 mph. Opposite-direction traffic separated by a safety island or raised median does not have to stop.

What is the safe following distance in New Jersey, and how does weather change it?

Increase the space when traveling faster or when road, traffic, or weather conditions are poor.

7. NJ School Bus Law: Stop Distance, 300 Feet Behind Emergency Vehicles & Move Over

Do you have to stop for a school bus on a divided highway in New Jersey, and what is the fine for passing one illegally? These are two of the most frequently tested topics on the New Jersey permit exam.

School Buses

• When a school bus stops with flashing red lights and an extended stop arm, all traffic in both directions must stop on undivided roads.
• On a two-lane road or a multi-lane road separated only by painted lines, traffic in both directions must stop at least 25 feet from the bus.
• Oncoming traffic on the opposite side of a safety island or raised median must slow to no more than 10 mph.
• You must remain stopped until the red lights stop flashing and the stop arm is retracted.
• Improperly passing a school bus is a 5-point motor-vehicle violation and carries additional statutory penalties.
• Railroad crossings: School buses must stop at ALL railroad crossings, with or without passengers, even if no lights are flashing and no train is visible. This is a frequently tested rule.

Emergency Vehicles

• When you see or hear an emergency vehicle (police, fire, ambulance) with lights or siren: pull to the extreme right and stop. Do not block intersections. After it passes, stay at least 300 feet behind a signaling emergency vehicle.
• Move Over Law (New Jersey): When approaching a stationary authorized emergency vehicle, tow truck, highway-maintenance or service vehicle displaying qualifying lights, or a disabled vehicle displaying hazard signals, flares, or reflective triangles, move over one lane when possible.

• Headlights required in New Jersey from half hour after sunset to half hour before sunrise, when visibility is 500 feet or less, when using windshield wipers, and when encountering fog, mist, or smoke.
• In heavy fog, use low beams, high beams reflect off fog and reduce visibility.
• If you start to hydroplane, ease off the gas gently. Do not brake hard or turn sharply.

When must you dim your high beams in New Jersey, and how far away does an oncoming car need to be? New Jersey law specifies exact distances for dimming, and the 500/300-foot rule is one of the most tested questions on the exam.

Key test point: The 500-foot / 300-foot rule is a classic exam question. Oncoming = 500 feet. Following = 300 feet. Dim accordingly.

14. Night Driving in NJ: High-Beam Glare, Visibility & Following Distance
