What does a flashing amber light indicate?

Answer: B — Proceed with caution

A flashing amber light is a signal for drivers to proceed with caution. This means that while you are not required to stop, you should reduce your speed and be prepared to react to any hazards that may be present. It often indicates that there is a potential hazard ahead or that the conditions may require you to be more vigilant. By understanding this signal, drivers can ensure they are alert and ready to respond appropriately to the situation, allowing for safer driving in potentially hazardous conditions. Other responses like stopping immediately or preparing for an emergency stop are not appropriate for a flashing amber light, as it is meant to prompt caution rather than an outright stop.
