Key DMV Words to Know
Right of way
The right to go first. When you 'have the right of way,' other drivers must wait for you.
Yield
Slow down and let other cars or people go first. It is NOT a complete stop, but you must wait if needed.
Merge
Smoothly move your car into another lane of traffic. You must match the speed of traffic and find a safe gap.
Pedestrian
A person who is walking — not in a car or bike. Pedestrians always have the right of way at crosswalks.
Crosswalk
A marked area where people can safely walk across the street. Always stop for pedestrians here.
School zone
An area near a school where you must drive more slowly to keep children safe.
Roundabout
A circular road junction where you drive around a center island. Cars inside the roundabout have the right of way.
Blind spot
An area around your car that you cannot see in your mirrors. Always turn your head to check blind spots before changing lanes.
BAC (Blood Alcohol Content)
A measure of how much alcohol is in your blood. In most US states, 0.08% BAC is the legal limit for driving.
DUI / DWI
Driving Under the Influence / Driving While Intoxicated. This means driving after drinking alcohol or taking drugs. It is illegal and very dangerous.
