What should a driver do if they cannot hear their siren during transport?

If a driver cannot hear their siren during transport, checking the siren by slowing down is an appropriate action because it allows the driver to assess whether the siren is functioning properly. Slowing down can help give the driver a clearer auditory experience to determine if the siren is operational, as loud noises from traffic or the surrounding environment may be masking the sound. Additionally, this approach emphasizes safety, as it enables the driver to maintain control of the vehicle while confirming the status of the siren.

This action is critical in emergency driving, where the ability to alert other road users is paramount. The siren serves as a communication tool to indicate an emergency vehicle's presence, and ensuring it works correctly can prevent potential accidents and ensure safe passage through traffic.
