Graduated Driver License (GDL)

New Jersey's three-stage licensing system for new drivers: student learner's permit, probationary license, and basic driver's license, each stage adding privileges only after supervised practice and clean driving time.

Related: Probationary License, Learner's Permit, Decal Requirement
Learner's Permit

A restricted credential issued after written and vision testing that lets a supervised beginner drive, typically valid for two years and requiring a licensed adult in the front passenger seat at all times.

Related: Supervising Driver, Graduated Driver License (GDL), Practice Log
Probationary License

The intermediate GDL stage granted after passing the road test; it carries curfew and passenger limits and is held for at least one year before a basic license is issued.

Related: Graduated Driver License (GDL), Curfew Restriction, Passenger Restriction
Decal Requirement

New Jersey rule requiring holders of a permit or probationary license to display reflective decals on the vehicle's license plates so other motorists can identify a novice driver.

Related: Probationary License, Learner's Permit
Curfew Restriction

A GDL limit barring probationary drivers from operating between specified late-night and early-morning hours unless an approved exception such as work, school, or religious activity applies.

Related: Probationary License, Passenger Restriction
Passenger Restriction

A GDL rule capping how many non-family passengers a probationary driver may carry, designed to reduce peer distraction during the highest-risk first year of solo driving.

Related: Curfew Restriction, Distracted Driving, Probationary License
Supervising Driver

The licensed adult who must sit beside a permit holder; New Jersey requires the supervisor to be at least 21, hold a valid license for three years, and remain seated in the front passenger position.

Related: Learner's Permit, Practice Log
Practice Log

A written record of supervised driving hours a permit holder must accumulate and present at the road test, documenting varied conditions such as night, highway, and inclement weather driving.

Related: Supervising Driver, Road Test
Road Test

The behind-the-wheel skills examination that measures basic vehicle control, observation, signaling, and compliance with traffic law before a probationary license is granted.

Related: Practice Log, Student Evaluation
Point System

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.

Related: Driver Improvement Program, Moving Violation
Moving Violation

Any traffic offense committed while the vehicle is in motion, such as speeding or failing to yield, as distinguished from non-moving equipment or parking offenses that carry no points.

Related: Point System, Reckless Driving
Reckless Driving

Operating a vehicle with willful or wanton disregard for the safety of persons or property; a serious offense carrying heavy penalties, points, and possible license suspension.

Related: Moving Violation, Careless Driving
Careless Driving

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.

Related: Reckless Driving, Following Distance
Implied Consent Law

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.

Related: DUI, Breath Alcohol Concentration (BAC)
DUI

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.

Related: Breath Alcohol Concentration (BAC), Implied Consent Law, Field Sobriety Test
Breath Alcohol Concentration (BAC)

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.

Related: DUI, Implied Consent Law
Field Sobriety Test

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.

Related: DUI, Implied Consent Law
Distracted Driving

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.

Related: Passenger Restriction, Following Distance
Fatigue Impairment

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.

Related: Distracted Driving, Defensive Driving
Defensive Driving

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.

Related: Following Distance, Space Cushion, Hazard Perception
Following Distance

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.

Related: Space Cushion, Tailgating, Careless Driving
Space Cushion

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.

Related: Following Distance, Defensive Driving
Hazard Perception

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.

Related: Defensive Driving, Space Cushion
Tailgating

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.

Related: Following Distance, Space Cushion
Hydroplaning

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.

Related: Skid Recovery, Space Cushion
Skid Recovery

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.

Related: Hydroplaning, Threshold Braking
Threshold Braking

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.

Related: Antilock Braking System (ABS), Skid Recovery
Antilock Braking System (ABS)

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.

Related: Threshold Braking, Electronic Stability Control
Electronic Stability Control

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.

Related: Antilock Braking System (ABS), Tire Tread Depth
Tire Tread Depth

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.

Related: Hydroplaning, Pre-Trip Inspection
Pre-Trip Inspection

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.

Related: Tire Tread Depth, Head Restraint
Head Restraint

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.

Related: Safety Belt Use, Pre-Trip Inspection
Safety Belt Use

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.

Related: Head Restraint, Child Passenger Safety Seat
Child Passenger Safety Seat

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.

Related: Safety Belt Use
Move Over Law

The requirement to slow down and, where possible, shift lanes away from stopped emergency, tow, or maintenance vehicles displaying flashing lights, protecting roadside workers.

Related: Work Zone Safety, Hazard Perception
Work Zone Safety

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.

Related: Move Over Law, Flagger
Flagger

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.

Related: Work Zone Safety, Move Over Law
School Bus Stop Law

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.

Related: Move Over Law, Hazard Perception
Sharing the Road

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.

Related: School Bus Stop Law, Space Cushion
No-Zone

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.

Related: Sharing the Road, Space Cushion
Instructor Ethics

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.

Related: Student Evaluation, Behind-the-Wheel Instruction
Student Evaluation

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.

Related: Road Test, Instructor Ethics, Behind-the-Wheel Instruction
Behind-the-Wheel Instruction

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.
