What action must be taken when a vehicle approaches a flashing red light?

When a vehicle approaches a flashing red light, the correct action is to stop completely and then proceed with caution. This traffic signal indicates that the driver must treat the intersection as if it were a stop sign. Stopping completely is essential for ensuring the safety of all road users, as it allows drivers to check for any oncoming traffic or pedestrians before continuing through the intersection.

Proceeding with caution after stopping is crucial because it emphasizes the need to remain aware of other vehicles and pedestrians that may also be navigating the intersection. This practice helps prevent accidents and ensures that drivers are making safe decisions based on the circumstances present at that moment.

The other options do not reflect the legal requirements associated with a flashing red light, which could lead to dangerous situations on the road. For instance, slowing down and proceeding without stopping does not guarantee a thorough check of the intersection, while speeding up to cross the intersection may result in a failure to yield to necessary right-of-way considerations. Ignoring the light entirely, even if the path seems clear, also dismisses the responsibility of adhering to traffic rules meant for everyone's safety.
