What does a flashing red traffic signal mean?

Answer: B — Treat it as a stop sign; come to a complete stop before proceeding

A flashing red traffic signal indicates that drivers must treat it as a stop sign. When you encounter a flashing red light, it is necessary to come to a complete stop at the intersection, ensuring that it is safe to continue before proceeding. This rule is in place to ensure the safety of all road users, as it requires drivers to assess oncoming traffic and any pedestrians that may be crossing. This is similar to the function of a stop sign, where the objective is to pause, take in your surroundings, and yield the right of way if necessary. Drivers need to be aware that while it may seem like a similar directive to a yield sign, which only requires slowing down and yielding if approached by other vehicles, a flashing red light demands a full stop first. It's crucial for drivers to adhere to this signal to prevent accidents and keep traffic moving safely.
