Flashing lights are permitted on which type of vehicles?

The correct answer pertains to the specific regulations governing flashing lights on vehicles. Flashing lights are explicitly permitted on emergency vehicles and school buses due to their roles in public safety. Emergency vehicles utilize flashing lights to alert other road users of their presence, particularly when responding to emergencies or navigating through traffic situations where immediate attention is required.

School buses are equipped with flashing lights to ensure the safety of children as they embark or disembark. When the lights are activated, it signals to other drivers to stop, creating a safe environment for children.

In contrast, not all commercial vehicles are authorized to use flashing lights, as their use is generally regulated depending on the nature of the vehicle and its intended operation. Passenger cars also do not typically have flashing lights, as these are not needed or legally required for standard operation. Therefore, the specific authorization for flashing lights is strictly applicable to emergency vehicles and school buses.
