Final answer:
A red flashing light means you must stop and proceed with caution. It requires a complete stop, similar to a stop sign, and you may go ahead when it is safe.
Step-by-step explanation:
The answer to what a red flashing light means in traffic is: d. Stop and proceed with caution. When you encounter a red flashing light, it acts much like a stop sign. You must come to a complete halt, check for other vehicles and pedestrians, and proceed when you know it is safe to do so. Traffic entering has to stop and yield to pedestrians and other traffic that may be crossing or on the road already. It's critical to be fully aware of your surroundings before proceeding.
Examples:
If it's late at night and the traffic is minimal, you still need to stop at a red flashing light, but you may proceed sooner if no one else is around.
- During busy traffic times, stopping at the red flashing light, you must wait until it is safe to cross, considering the higher volume of traffic.
