Final answer:
A flashing red light at an intersection is treated like a stop sign, requiring drivers to stop completely and proceed when safe. It aims to slow down vehicles, thus improving safety. 'NO TURN ON RED' does not apply here unless indicated by signs.
Step-by-step explanation:
A flashing red light at an intersection is treated the same way as a stop sign. This means the correct answer to the question, "What does a flashing red light mean?" is B. The same thing as a stop sign. It requires all drivers to come to a complete stop, check for oncoming traffic from all directions, and proceed with caution when the intersection is clear. It's important to stop to ensure not only your safety but also the safety of pedestrians and other drivers. Answer C, NO TURN ON RED, would not apply in this situation unless specifically marked by an additional sign. Many vehicles speed through intersections and do not adhere to speed limits; however, a traffic control device such as a flashing red light mandates drivers to slow down, thereby enhancing pedestrian safety and overall intersection safety. When you encounter a flashing red light at a traffic signal, you are required to come to a complete stop, similar to stopping at a stop sign. After stopping, you may proceed when it is safe to do so, following the right-of-way rules.
