Arizona Driving Permit Written Practice Test

What does a red traffic light signify?

1. Slow down and prepare to stop

2. Stop; do not proceed until the light turns green

3. Yield to oncoming traffic

4. Proceed with caution

The correct answer is: Stop; do not proceed until the light turns green

A red traffic light clearly indicates that drivers must stop their vehicles. This is a critical rule in traffic management, ensuring safety on the roads. The purpose of the red light is not only to control the flow of traffic but also to prevent accidents at intersections. Drivers must come to a complete stop and remain there until the light changes to green, which authorizes them to proceed. Other options may suggest actions that could lead to confusion or unsafe driving practices. For instance, slowing down and preparing to stop could result in drivers misjudging the need to halt completely. Yielding to oncoming traffic is not applicable at a red light, as it primarily pertains to situations where right-of-way must be observed. Lastly, proceeding with caution contradicts the requirement to stop entirely at a red signal, as this could lead to dangerous situations for both the driver and others on the road. Understanding the importance of adhering strictly to a red light is essential in fostering a safe driving environment.
