How far should you stay behind a fire truck when it is responding to a fire alarm?

Answer: C — 500 feet

When a fire truck is responding to a fire alarm, it is crucial to keep a safe distance behind it to allow the firefighters to perform their duties efficiently and safely. The correct answer is to stay 500 feet behind a fire truck when it is responding to a fire alarm. This distance gives the firefighters enough space to maneuver and make necessary stops or turns without risking a collision with your vehicle. It also helps to maintain good visibility of the fire truck's signals and movements, allowing you to react appropriately to any sudden changes in traffic flow. This distance ensures the safety of both the firefighters and other drivers on the road.
