Washington Written Drivers Permit Practice Test

What does a flashing yellow light indicate?

1. Stop immediately

2. Proceed with caution

3. Only turn left

4. Speed up to clear the intersection

The correct answer is: Proceed with caution

A flashing yellow light signals to drivers that they should proceed with caution. This traffic signal alerts motorists to be aware and to be prepared for potential hazards in the road ahead, such as pedestrians or other vehicles that may not be following the rules as expected. It does not require a complete stop, but instead encourages drivers to slow down and ensure that the intersection or area is clear before moving forward. The other choices present actions that are not appropriate for a flashing yellow light. Stopping immediately would be incorrect since this is not a red light; only turning left restricts driver's options unnecessarily; and speeding up to clear the intersection could lead to dangerous situations, as caution is required rather than speed.
