Driver vocabulary
Short explanations for words that can be confusing if you are new to driving or learning in a second language.
Includes road layout, parking, signs, vehicle control, and safety vocabulary.
A circular intersection where traffic moves around a center island, usually counterclockwise in the U.S.
Why it matters: You usually slow down, yield to traffic already inside, then enter when there is a safe gap.
Example: If a car is already coming around from your left, wait before entering.
A raised part of the road that makes drivers slow down.
Why it matters: Going too fast over one can damage the car, surprise passengers, or make you lose control.
Example: In a parking lot, brake before the bump, then roll over it slowly.
Parking in line with the curb, usually between two cars, with your vehicle facing the same direction as traffic.
Why it matters: The DMV may ask about curb distance, wheel direction on hills, and safe backing.
Example: Signal, pull beside the front car, back in slowly, then straighten near the curb.
An area beside or behind your car that mirrors may not show clearly.
Why it matters: A car, motorcycle, or bicyclist can hide there, so you need a quick shoulder check.
Example: Before changing lanes, check mirrors, signal, then glance over your shoulder.

Why it matters: Many crashes happen when someone assumes they can go first. When unsure, slow down and yield.
Example: At a four-way stop, the driver who stopped first usually goes first.
Joining a lane of traffic, usually from an entrance ramp or from a lane that is ending.
Why it matters: You need to match traffic speed and find a safe gap without forcing others to brake hard.
Example: On a freeway ramp, accelerate smoothly, signal, check the gap, then enter.
