What is the maximum distance an operator may follow an ambulance when it is displaying headlights?

The maximum distance an operator may follow an ambulance when it is displaying headlights is 500 feet. This regulation is designed to ensure that emergency vehicles can respond quickly and safely without being obstructed by other traffic. By restricting the distance to 500 feet, it provides a clear buffer zone around the ambulance, reducing the risk of collisions and allowing other drivers to react appropriately when they see an ambulance with its lights on. Properly understanding and adhering to this regulation is vital for maintaining public safety during emergency situations.
