A recent study highlights the potential increase in crash risk when ambulances operate with lights and sirens. When an ambulance responds to an emergency call without using lights and sirens, the crash rate is 4.6 per 100,000 responses. The crash rate increases to 5.5 when lights and sirens are used. The increase in risk is even greater when the ambulance is transporting a victim. The crash risk without lights and sirens is 7.0 per 100,000 transports, and increases to 16.5 when lights and sirens are used throughout the transport.
