What does a flashing red traffic light mean?

A flashing red traffic light indicates that a driver must come to a complete stop, similar to how one would respond to a stop sign. This signal requires the driver to ensure the way is clear and safe before proceeding through the intersection or past the light.

This traffic control device is typically used in situations where caution is essential, such as at intersections or locations where visibility may be limited. Although the other choices may imply some form of caution or yielding, they do not explicitly address the critical action of stopping first, which is fundamental to maintaining safety for all road users. By requiring a complete stop, it ensures that drivers can assess their surroundings and make informed decisions before moving forward, thereby reducing the risk of accidents.
