DMV Glossary

Plain-English definitions of the terms that show up on every state's DMV written test. Citable, with sources. Updated for 2026.

Definition

Implied Consent

By driving on public roads you automatically consent to a chemical test if police suspect DUI. Refusing triggers automatic license suspension in all 50 states — separate from any criminal charge.

Definition

Driver's License Point System

Each traffic violation conviction adds demerit points to your driving record. Accumulate enough points in a rolling window and the DMV issues a warning, hearing, or license suspension.

Definition

The 3-Second Rule

Keep at least 3 full seconds of gap between your vehicle and the car ahead. At 60 mph that's 264 feet. Every state DMV handbook recommends it as the minimum following distance under normal conditions.

Definition

Permit vs License

A learner's permit is a temporary credential that lets a new driver practice behind the wheel under adult supervision; a driver's license is the credential that authorizes solo driving on public roads.

Definition

Graduated Driver Licensing (GDL)

The three-stage licensing system US states use for new drivers: learner's permit, provisional license, then full license. Each stage has restrictions that relax as the driver gains experience.

Definition

Provisional License

A provisional license (also called an intermediate license) lets you drive solo but with restrictions — night curfews and passenger limits — until you reach the state's age or violation-free period requirement.
