Final answer:
At a red traffic light, drivers must stop completely and wait for the signal to turn green. A flashing red light is treated like a stop sign, where drivers must stop and then proceed when safe.
Step-by-step explanation:
The rules for a red traffic light and a flashing red traffic light are fundamental for road safety and proper traffic flow. For a solid red traffic light, the rule is to come to a complete stop at the stop line, and you must remain stopped until the light turns green. In contrast, a flashing red traffic light should be treated like a stop sign; this means that after coming to a full stop, the driver should proceed when it is safe to do so, yielding to other traffic and pedestrians that have the right of way.
