What is the appropriate action when a flashing red light is observed?

Answer: B — Come to a full stop and proceed when safe

When encountering a flashing red light, the appropriate action is to come to a full stop and proceed when it is safe. A flashing red light signals that the driver must treat the situation as if it were a stop sign. This means that all vehicles must halt completely at the intersection and yield to any pedestrians or other vehicles that may have the right of way. Once the intersection is clear and it is safe to continue, the driver may proceed. This rule ensures that all drivers are vigilant and cautious at potentially hazardous intersections. By stopping fully, drivers can assess the situation, which helps prevent accidents and enhances roadway safety. The requirement to stop is crucial, as it mandates attention and consideration for other road users, maintaining order at the intersection and reducing the risk of collisions.
