What does a flashing red traffic light indicate?

A flashing red traffic light indicates that drivers must come to a complete stop and then proceed when it is safe to do so. This signal functions similarly to a stop sign; it requires drivers to halt their vehicles and assess the intersection to ensure that it is clear of any other vehicles or pedestrians before continuing.

This rule emphasizes the safety of all road users by requiring drivers to acknowledge potential hazards and make informed decisions. As a result, stopping at a flashing red light helps prevent accidents, allowing for a safer flow of traffic.

The other choices do not align with the meaning of a flashing red light. Simply speeding up or preparing to stop does not ensure safety, nor does it involve taking the necessary precautions to check for hazards at the intersection.
