Idaho Written Driver's License Practice Test

What should you do if a traffic signal is yellow as you approach an intersection?

1. Speed up to pass through the intersection

2. Prepare to stop if it is safe to do so

3. Ignore the signal and continue

4. Stop immediately regardless of conditions

The correct answer is: Prepare to stop if it is safe to do so

When you encounter a yellow traffic signal as you approach an intersection, the correct action is to prepare to stop if it is safe to do so. A yellow signal indicates that the light is about to change to red, and it is a warning to drivers that they should slow down and be ready to stop for oncoming traffic or pedestrians. This response emphasizes safety and good driving practices. Preparing to stop allows you to assess the situation: if stopping safely is possible without causing an accident, then you should do so. This approach also respects the right-of-way of other vehicles and pedestrians who may be crossing the intersection. In contrast, speeding up to pass through the intersection can lead to dangerous situations, especially if the light turns red while you are in the intersection. Ignoring the signal is not only unsafe but also illegal, while stopping immediately without assessing the conditions could put you at risk of being rear-ended by vehicles behind you, especially if they are unable to react in time. Hence, preparing to stop while considering safety is the most responsible course of action.
