Topic overview

This section covers the rules of the road — right-of-way, passing, turns, roundabouts, school buses, and emergency vehicles. Your highest duty as a motorist is to drive carefully and prudently and to avoid striking a pedestrian or another vehicle. The law only says who must yield; it does not give any driver the right-of-way.

Right-of-way rules depend on the situation. Drivers turning left must yield to oncoming vehicles going straight, and at an uncontrolled intersection with no stop sign or signal (except roundabouts) you must yield to vehicles coming from the right. When approaching a roundabout, always yield to traffic already in the circle and to pedestrians in the crosswalks, and wait for a gap before entering; inside, you go counterclockwise and should never make a left turn to enter.

You must stop for a stopped school bus with its alternating flashing red lights and stop arm activated when you are on a two-lane road or a two-lane one-way street, though you do not have to stop when traveling the opposite direction on a divided highway with separate roadways. You must also yield to emergency vehicles using a siren and a red or blue flashing light by pulling to the right edge and stopping. When you turn, signal at least 100 feet before turning, and turn from the lane closest to the direction you want to go.

Who yields at an uncontrolled intersection with no stop sign or signal?

Except at roundabouts, drivers must yield to vehicles coming from the right.

When do I have to stop for a stopped school bus?

When a stopped school bus activates its alternating flashing red lights and stop arm, oncoming and following traffic must stop on a two-lane road or a two-lane one-way street; you do not have to stop when going the opposite direction on a divided highway with separate roadways.

How far ahead should I signal before turning?

Signal at least 100 feet before you turn, using either hand-and-arm signals or your vehicle's turn signals and brake lights.
