Graduated Driver Licensing (GDL)

A phased licensing system that moves new drivers from a learner permit through intermediate restrictions to a full license as experience and age increase. New Hampshire applies it to drivers under 21.

Related: Learner Permit, Intermediate License, Driver Education Certificate
Learner Permit

A restricted credential issued to a beginning driver who has passed the vision and knowledge tests. It allows driving only while supervised by a qualified licensed adult and is subject to curfew and passenger limits.

Related: Supervising Driver, Graduated Driver Licensing (GDL), Driver Education Certificate
Driver Education Certificate

The document a state-approved driver education program issues to confirm a student completed the required classroom and behind-the-wheel instruction. It must be presented before the student can advance to the next licensing stage.

Related: Driver Education Program Approval, Behind-the-Wheel Instruction, Learner Permit
Driver Education Program Approval

State recognition that a school's curriculum, instructors, vehicles, and records meet minimum standards. Only approved programs may issue certificates accepted for licensing, so instructors must know which requirements are mandatory.

Related: Driver Education Certificate, Instructor Certification, Behind-the-Wheel Instruction
Instructor Certification

The credential an instructor must hold to teach driver education in the state. It typically requires a clean driving record, background check, and completion of an approved instructor preparation course.

Supervising Driver

The licensed adult who must sit beside a learner permit holder during practice driving. This person is legally responsible for the learner's operation of the vehicle and must meet age and record requirements.

Related: Learner Permit, Supervised Driving Log, Parental Consent
Supervised Driving Log

A written record of practice hours completed by a learner with a supervising driver. Many states require a signed log before the learner may take the road test, and falsifying it can delay licensing.

Related: Supervising Driver, Learner Permit, Road Test
Parental Consent

Written permission from a parent or legal guardian that allows a minor to apply for a permit or license. Without it, the licensing agency will not process the application.

Related: Learner Permit, Supervising Driver, Supervised Driving Log
Road Test

The scored on-road evaluation of a candidate's vehicle control, observation, and rule compliance. Passing it is required for a license, and instructors should prepare students for the specific maneuvers and scoring criteria used.

Related: Behind-the-Wheel Instruction, Learner Permit, Defensive Driving
Vision Screening

The eye test required before a permit or license is issued. A candidate who fails may need corrective lenses, and a restriction requiring glasses or contacts will be printed on the license.

Related: Learner Permit, License Restriction, Road Test
License Restriction

A condition printed on a license that limits when or how a person may drive, such as corrective lenses, daylight-only driving, or an ignition interlock requirement. Driving outside the restriction is a violation.

Related: Vision Screening, Ignition Interlock Device, Graduated Driver Licensing (GDL)
Right-of-Way

The legal priority to proceed through an intersection or roadway space. It is yielded, not taken, and drivers must follow signals, signs, and established rules when priorities conflict.

Related: Four-Way Stop, Left Turn Yield, Defensive Driving
Four-Way Stop

An intersection where all approaches face stop signs. Vehicles proceed in arrival order, and if two arrive together the one on the right goes first unless a left-turning vehicle must yield.

Related: Right-of-Way, Left Turn Yield, Stop Line
Left Turn Yield

The rule that a driver turning left across oncoming traffic must wait for a safe gap and yield to vehicles going straight or turning right. This applies even when the light is green unless a protected arrow is shown.

Related: Right-of-Way, Four-Way Stop, Protected Left Turn
Protected Left Turn

A left turn made on a green arrow that gives the turning driver exclusive right-of-way while oncoming traffic is stopped. Instructors teach students to confirm the arrow and watch for vehicles still clearing the intersection.

Related: Left Turn Yield, Right-of-Way, Traffic Signal Phases
Following Distance

The gap a driver keeps behind the vehicle ahead, commonly measured with the three-second rule. It should increase in rain, snow, darkness, or when following large trucks that block the view.

Related: Three-Second Rule, Stopping Distance, Defensive Driving
Three-Second Rule

A method of checking following distance by counting the seconds between when the vehicle ahead passes a fixed object and when your own vehicle reaches it. Fewer than three seconds means the gap is too close.

Related: Following Distance, Stopping Distance, Space Cushion
Space Cushion

The buffer of empty roadway a driver maintains around the vehicle on all sides. It gives room to react and maneuver when another driver makes an error or a hazard appears suddenly.

Related: Following Distance, Defensive Driving, Blind Spot
Stopping Distance

The total distance a vehicle travels from the moment a hazard is seen until it stops. It combines perception, reaction, and braking distance and grows with speed and slippery surfaces.

Related: Following Distance, Hydroplaning, Skid Recovery
Defensive Driving

A driving approach that anticipates hazards, assumes other drivers may err, and plans escape routes. It emphasizes observation, space management, and avoiding reliance on other drivers' correct behavior.

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

The area beside and behind a vehicle that mirrors do not show. Drivers must turn their head to check it before changing lanes, and instructors teach students to avoid lingering in other vehicles' blind spots.

Related: Space Cushion, Lane Change Procedure, Mirror Adjustment
Lane Change Procedure

The sequence of checking mirrors, signaling, checking the blind spot, and moving smoothly only when clear. Skipping the head check is a common cause of collisions and a frequent road-test error.

Related: Blind Spot, Mirror Adjustment, Turn Signal Use
Mirror Adjustment

Setting the rearview and side mirrors to minimize blind spots before driving. Proper adjustment reduces the head movement needed to check adjacent lanes and supports safe lane changes.

Related: Blind Spot, Lane Change Procedure, Pre-Trip Inspection
Turn Signal Use

Activating the directional indicator before turning or changing lanes, early enough to warn others. Failing to signal is a moving violation and a common contributor to intersection crashes.

Related: Lane Change Procedure, Right-of-Way, Traffic Signal Phases
Traffic Signal Phases

The sequence of green, yellow, and red indications, including arrows, that controls movement at a signalized intersection. A steady yellow means stop if safe, not accelerate.

Related: Protected Left Turn, Right-of-Way, Stop Line
Stop Line

The painted line marking where a vehicle must stop at a sign or signal. Stopping past it, or rolling through, is a violation and a point of emphasis during the road test.

Related: Four-Way Stop, Traffic Signal Phases, Road Test
Skid Recovery

The technique of easing off the accelerator, steering where you want the front of the vehicle to go, and avoiding hard braking during a loss of traction. Sudden inputs make a skid worse.

Related: Stopping Distance, Hydroplaning, Defensive Driving
Hydroplaning

Loss of tire contact with the road when water builds under the tread. The driver should ease off the accelerator, avoid braking hard, and hold the wheel steady until grip returns.

Related: Skid Recovery, Stopping Distance, Following Distance
Behind-the-Wheel Instruction

Supervised in-vehicle training in which a student practices vehicle control and traffic skills. It must occur in a dual-control vehicle with a certified instructor and follow a documented lesson plan.

Related: Dual Control Vehicle, Lesson Plan, Instructor Certification
Dual Control Vehicle

A training car equipped with a passenger-side brake and often a second mirror, allowing the instructor to intervene. It must be inspected, insured, and marked as required by state rules.

Related: Behind-the-Wheel Instruction, Instructor Certification, Pre-Trip Inspection
Lesson Plan

A structured outline of objectives, activities, and assessment for a driving session. It keeps instruction progressive and gives the instructor and student a shared standard for measuring progress.

Related: Behind-the-Wheel Instruction, Instructor Liability, Hazard Perception
Instructor Liability

The legal exposure an instructor carries for student safety during training. It is managed through proper supervision, vehicle maintenance, documented lessons, and immediate intervention when a student is overmatched.

Related: Dual Control Vehicle, Lesson Plan, Instructor Certification
Hazard Perception

The ability to notice developing risks early and decide on a response. Instructors build it by narrating scenes, asking students to predict, and reviewing near misses after each drive.

Related: Defensive Driving, Space Cushion, Lesson Plan
Pre-Trip Inspection

The check of tires, lights, brakes, mirrors, and fluid levels before driving. Instructors teach it as a habit and must confirm the training vehicle is roadworthy before each lesson.

Demerit Point System

A record-keeping scheme that assigns points to convictions for moving violations. Accumulating points within a set period triggers warnings, suspension, or required driver improvement action.

Related: Habitual Offender, License Suspension, Driver Improvement Program
License Suspension

A temporary withdrawal of driving privileges for a set period or until conditions are met. Driving during a suspension is a separate offense and can extend the loss of license.

Related: Demerit Point System, Habitual Offender, Ignition Interlock Device
Habitual Offender

A driver whose repeated convictions within a defined period classify them for an extended license revocation. The status typically follows multiple serious violations and requires a formal reinstatement process.

Related: Demerit Point System, License Suspension, Driver Improvement Program
Driver Improvement Program

A course or counseling requirement imposed after a certain number of points or a specific violation. Completion may avoid suspension or be a condition of reinstatement.

Impaired Driving

Operating a vehicle while affected by alcohol, drugs, or a combination that reduces the ability to drive safely. It is a criminal offense and a leading cause of fatal crashes for young drivers.

Related: Implied Consent, Ignition Interlock Device, Zero Tolerance
Implied Consent

The legal principle that a licensed driver has already agreed to submit to chemical testing when lawfully arrested for impaired driving. Refusal usually brings automatic administrative penalties.

Related: Impaired Driving, Zero Tolerance, License Suspension
Zero Tolerance

A policy that penalizes drivers under 21 for operating with any measurable alcohol in their system, below the adult threshold. It reflects the higher risk of impairment in novice drivers.

Related: Impaired Driving, Implied Consent, Graduated Driver Licensing (GDL)
Ignition Interlock Device

A breath-test unit wired to the ignition that prevents starting if alcohol is detected. Courts and licensing agencies order it for certain impaired-driving convictions or as a reinstatement condition.
