True or false: Hazard lamps will flash when the service brake is applied.

The statement that hazard lamps will flash when the service brake is applied is false. Hazard lights, also known as emergency flashers, are designed to alert other drivers that a vehicle is stationary or experiencing an emergency situation. They are activated separately from the normal operation of the vehicle's brake lights.

When the service brake is applied, it causes the brake lights to illuminate, signaling to vehicles behind that the vehicle is slowing down or stopping. However, this does not engage the hazard lamps. The two systems operate independently. This separation is crucial for clarity on the road, as brake lights indicate a change in motion, while hazard lights convey that a vehicle may not be moving at all or is in an unusual situation.

Understanding this operating principle helps clarify the functionality of vehicle lighting systems and their respective signals to other drivers on the road.
