Final answer:
At a flashing red traffic signal, a driver should come to a complete stop before proceeding, treating it like a stop sign. They can proceed when it is safe to do so, following the right-of-way rules.
Step-by-step explanation:
At a flashing red traffic signal, a driver should come to a complete stop before proceeding. A flashing red signal indicates the same requirement as a regular red signal: stop and yield to other traffic.
Drivers should treat a flashing red signal like a stop sign. After stopping, they can proceed when it is safe to do so, following the right-of-way rules.
It's important to note that a flashing red signal is different from a flashing yellow signal, which indicates caution and drivers should proceed with care.
