USAREUR Practice Exam

What must a driver do when the traffic light changes from green to yellow?

1. Speed up to pass before it turns red.

2. Stop only if other vehicles are nearby.

3. Slow down and prepare to stop if safe to do so.

4. Make a U-turn if possible.

The correct answer is: Slow down and prepare to stop if safe to do so.

When a traffic light changes from green to yellow, the appropriate action for a driver is to slow down and prepare to stop if it is safe to do so. This response indicates an understanding of traffic signals and the rules of the road, as a yellow light serves as a warning that the signal is about to turn red. The intent of the yellow light is to allow drivers to safely navigate the intersection without running a red light, which could lead to accidents. The emphasis on slowing down reflects responsible driving behavior, taking into account both the driver’s safety and that of other road users. By preparing to stop, the driver is being cautious and mindful, especially since approaching vehicles may also react to the light change. This proactive approach helps maintain traffic flow and minimizes the risk of collisions. In contrast, other choices involve either speeding up, which can result in running a red light, or ambiguous stopping guidelines that don't prioritize safety. Making a U-turn during this transition can also be dangerous and is generally not advised in such scenarios.
