What does a flashing red traffic light indicate?

A flashing red traffic light indicates that drivers must come to a complete stop at the intersection, similar to a stop sign. After stopping, drivers may proceed only when it is safe to do so, allowing for other vehicles or pedestrians that may have the right of way. This signal is crucial for ensuring that drivers are fully aware of their surroundings and can navigate the intersection safely without the risk of colliding with other traffic or pedestrians.

In contrast to the other responses, which imply varying levels of caution or action, the flashing red light clearly mandates a complete stop. Choices suggesting to slow down or proceed with caution may lead to dangerous situations if drivers do not come to a full stop first. Continuing to drive without stopping conflicts with traffic laws and could result in accidents. Preparing to stop and watching for pedestrians is important, but it does not capture the essential requirement that a full stop must occur before any further action is taken.
