What must you do if you come across a flashing red light at an intersection?

When encountering a flashing red light at an intersection, the correct response is to stop and then proceed if it is safe to do so. This traffic signal functions similarly to a stop sign, indicating that all drivers must come to a complete stop. It requires you to assess the situation and ensure that the intersection is clear of any obstacles or oncoming vehicles before proceeding.

This approach prioritizes safety, allowing you to yield the right-of-way to other vehicles or pedestrians who may have a legal right to be in the intersection. It's a critical practice for preventing accidents and ensuring safe vehicle movement through the intersection.

The other responses do not align with the required traffic rules: merely waiting for a light to change is unnecessary and could cause confusion with other drivers; proceeding without stopping fails to prioritize safety; and speeding up is dangerous and illegal, increasing the risk of collisions. Always stopping and checking the intersection ensures a safer driving environment for you and others.
