Traffic signals and markings1 of 2
What is the legal meaning of a flashing red traffic signal at a Utah intersection?
The answer
Answer: B. A flashing red traffic signal has the exact same legal meaning as a stop sign. Motorists must come to a complete stop before the stop line or crosswalk, yield the right-of-way to oncoming cross traffic and pedestrians, and proceed only when it is safe to do so.
