Final answer:
1) Stop and yield the right-of-way to other vehicles and pedestrians, A flashing red light at an intersection means a driver must stop and yield the right-of-way to other vehicles and pedestrians.
Step-by-step explanation:
A flashing red light at an intersection means a driver must stop and yield the right-of-way to other vehicles and pedestrians. It is important to come to a complete stop and wait for a safe opportunity to proceed. Ignoring the light or speeding up to clear the intersection quickly would be dangerous and against traffic laws.
A flashing red light at an intersection means that a driver must follow option 1) Stop and yield the right-of-way to other vehicles and pedestrians. A flashing red light is equivalent to a stop sign, signifying that the driver must come to a complete stop, yield to any oncoming traffic, and proceed only when it is safe to do so.
Ignoring the light (option 4) or speeding up (option 3) is against traffic regulations and can lead to accidents. Proceeding with caution (option 2) is applicable to a flashing yellow light, not a flashing red one, where stopping is required.
