Idaho Written Driver's License Practice Test

At a flashing yellow traffic signal, the appropriate action is to slow down and proceed with caution. This signal alerts drivers that they should approach the intersection carefully, as there might be cross traffic or pedestrians that have the right of way. The purpose of a flashing yellow is to indicate that it is not a stop signal, but rather a warning to be vigilant and prepared to yield if necessary. This enhances safety by ensuring drivers do not just rush through the intersection, which could lead to accidents.

The other actions, such as coming to a complete stop or speeding up, do not align with the signal's intent and could increase the risk of collisions. Ignoring the signal altogether is also not advisable, as it disregards the important warning being provided. Thus, slowing down and being cautious ensures a safer driving experience at intersections equipped with a flashing yellow signal.
