What must a driver do when approaching a flashing red traffic light?

When approaching a flashing red traffic light, the driver must stop and proceed when it is safe to do so. A flashing red light functions in a similar way to a stop sign, indicating that the vehicle must come to a complete stop at the intersection. After stopping, the driver should check for any oncoming traffic or pedestrians, and only proceed when it is safe to exit the intersection. This ensures that all traffic rules are followed and helps prevent accidents, as the light signals that cross traffic may have the right of way or that other vehicles may be approaching the intersection.

The other options present misunderstandings of how to appropriately respond to a flashing red light. Simply slowing down does not ensure that the driver has stopped, which is crucial for safety. Yielding to oncoming traffic or ignoring the light contradicts the requirement to stop and assess the situation before proceeding. Therefore, the correct action is to stop completely and then continue only when circumstances permit safe passage.
