The behind-the-wheel skills examination that measures basic vehicle control, observation, signaling, and compliance with traffic law before a probationary license is granted.
- Point System
- Related: Driver Improvement Program, Moving Violation
New Jersey's schedule that assigns points to moving violations; accumulating enough points triggers surcharges, license suspension, and mandatory completion of a driver improvement program.

- Careless Driving
- Related: Reckless Driving, Following Distance
Driving without due caution in a manner that endangers people or property but falls short of intentional disregard; commonly charged after a preventable collision or inattentive maneuver.
- Implied Consent Law
- Related: DUI, Breath Alcohol Concentration (BAC)
The rule that anyone operating a vehicle on New Jersey roads automatically agrees to submit to a breath or blood test when lawfully suspected of impaired driving, with refusal bringing automatic sanctions.
- DUI
- Related: Breath Alcohol Concentration (BAC), Implied Consent Law, Field Sobriety Test
Driving under the influence of alcohol or drugs to a degree that impairs safe operation; New Jersey also prohibits driving while at or above the legal blood alcohol limit regardless of visible impairment.
- Breath Alcohol Concentration (BAC)
- Related: DUI, Implied Consent Law
The percentage of alcohol in a person's bloodstream measured by breath testing; New Jersey's general adult limit is 0.08 percent, with stricter limits for commercial drivers and underage drivers.
- Field Sobriety Test
- Related: DUI, Implied Consent Law
A standardized roadside battery such as walk-and-turn, one-leg stand, or horizontal gaze nystagmus used to gather evidence of impairment and support a probable-cause arrest decision.
- Distracted Driving
- Related: Passenger Restriction, Following Distance
Any activity that diverts eyes, hands, or attention from the driving task, including texting, phone use, eating, grooming, and adjusting navigation; New Jersey law bans handheld phone and text use.
- Fatigue Impairment
- Related: Distracted Driving, Defensive Driving
Reduced alertness and reaction time caused by insufficient sleep or prolonged driving, producing effects comparable to alcohol and requiring rest rather than caffeine or willpower to reverse.
- Defensive Driving
- Related: Following Distance, Space Cushion, Hazard Perception
A proactive approach that assumes other road users may err, so the driver scans ahead, maintains space cushions, plans escape routes, and avoids relying on others to prevent a collision.
- Following Distance
- Related: Space Cushion, Tailgating, Careless Driving
The gap kept behind the vehicle ahead; the three-second rule gives a baseline that should grow in rain, darkness, heavy traffic, or when following large trucks and motorcycles.
- Space Cushion
- Related: Following Distance, Defensive Driving
The protective margin of empty roadway maintained around a vehicle on all sides so the driver has time to react and room to steer or brake when a hazard appears.
- Hazard Perception
- Related: Defensive Driving, Space Cushion
The skill of scanning far ahead and to the sides to detect developing risks, such as a ball rolling into the street or brake lights several cars ahead, before they become emergencies.
- Tailgating
- Related: Following Distance, Space Cushion
Following another vehicle too closely for the speed and conditions, reducing reaction time and contributing to rear-end collisions; it is a moving violation and a common road-rage trigger.
- Hydroplaning
- Related: Skid Recovery, Space Cushion
Loss of tire contact with the pavement when water builds between tire and road at speed, causing steering and braking to fade until speed drops and tread can channel water away.
- Skid Recovery
- Related: Hydroplaning, Threshold Braking
The technique of looking and steering where the driver wants to go while easing off the accelerator and avoiding hard braking, allowing the tires to regain grip progressively.
- Threshold Braking
- Related: Antilock Braking System (ABS), Skid Recovery
Braking firmly up to the point just before wheels lock, preserving steering control; on vehicles with antilock brakes the driver simply applies steady hard pressure and steers.
- Antilock Braking System (ABS)
- Related: Threshold Braking, Electronic Stability Control
An electronic system that rapidly releases and reapplies brake pressure to prevent wheel lockup, allowing the driver to steer while braking hard on slippery or emergency surfaces.
- Electronic Stability Control
- Related: Antilock Braking System (ABS), Tire Tread Depth
A system that detects loss of traction or yaw and selectively brakes individual wheels and reduces engine power to help the driver keep the vehicle on its intended path.
- Tire Tread Depth
- Related: Hydroplaning, Pre-Trip Inspection
The thickness of rubber remaining on a tire; worn tread lengthens stopping distance and raises hydroplaning risk, so tires should be replaced before reaching the legal minimum.
- Pre-Trip Inspection
- Related: Tire Tread Depth, Head Restraint
A systematic walk-around and in-cab check of tires, lights, fluids, mirrors, brakes, and safety equipment performed before driving to catch defects that could cause a breakdown or crash.
- Head Restraint
- Related: Safety Belt Use, Pre-Trip Inspection
The seat component positioned to limit rearward head movement in a collision; correct height places the top at ear level and close to the head to reduce whiplash injury.
- Safety Belt Use
- Related: Head Restraint, Child Passenger Safety Seat
New Jersey's primary enforcement law requires front-seat occupants and all passengers under 18 to be belted; proper wear places the lap belt low across the hips, not the abdomen.
- Child Passenger Safety Seat
- Related: Safety Belt Use
A federally rated restraint matched to a child's age, height, and weight, installed rear-facing for infants and in the back seat until the child outgrows the seat's limits.
- Move Over Law
- Related: Work Zone Safety, Hazard Perception
The requirement to slow down and, where possible, shift lanes away from stopped emergency, tow, or maintenance vehicles displaying flashing lights, protecting roadside workers.
- Work Zone Safety
- Related: Move Over Law, Flagger
Practices for driving through construction areas: reduce speed, obey flaggers and temporary signs, increase following distance, and avoid lane changes where workers and equipment are close.
- Flagger
- Related: Work Zone Safety, Move Over Law
A trained worker who controls traffic through or around a work zone using a stop/slow paddle or hand signals; drivers must obey the flagger as they would a police officer.
- School Bus Stop Law
- Related: Move Over Law, Hazard Perception
The rule requiring traffic in both directions to stop for a school bus with flashing red lights and extended stop arm, unless separated by a raised median or barrier.
- Sharing the Road
- Related: School Bus Stop Law, Space Cushion
The principle that drivers must give pedestrians, cyclists, motorcyclists, and large trucks appropriate space and legal right-of-way, recognizing their greater vulnerability or limited maneuverability.
- No-Zone
- Related: Sharing the Road, Space Cushion
The blind spots around a large commercial truck where the driver cannot see a nearby car; lingering there prevents the truck driver from reacting and risks a sideswipe or squeeze.
- Instructor Ethics
- Related: Student Evaluation, Behind-the-Wheel Instruction
The professional standards requiring honesty in evaluations, avoidance of harassment or bias, respect for student confidentiality, and refusal to certify skills a student has not actually demonstrated.
- Student Evaluation
- Related: Road Test, Instructor Ethics, Behind-the-Wheel Instruction
The ongoing, objective assessment of a learner's control, observation, and decision-making using defined criteria, documented so instruction can be adjusted and progress defended to the student.
- Behind-the-Wheel Instruction
- Related: Student Evaluation, Instructor Ethics
In-car coaching that gives clear pre-drive directions, brief in-motion cues, and structured post-drive feedback, gradually shifting responsibility to the student as competence grows.
