Arizona Driving Permit Written Practice Test

What does a red stop light mean?

1. Accelerate

2. Stop

3. Proceed with caution

4. Change lanes

The correct answer is: Stop

A red stop light indicates that all vehicles must come to a complete stop at the intersection. This signal is a crucial traffic control measure designed to maintain safety on the road. When a driver sees a red light, they must halt their vehicle before the crosswalk or intersection and remain stopped until the light turns green, allowing them to proceed safely. This rule is essential for preventing accidents and ensuring that all drivers follow the same protocols when navigating through intersections. In contrast, the other options suggest actions that would be inappropriate or dangerous at a red light.
