How must hazard lamps function during operation?

Hazard lamps are designed to function as a warning signal to other drivers, indicating that a vehicle is stationary or experiencing some kind of emergency. Their ability to operate simultaneously and independent of the ignition is crucial for safety. In situations where a vehicle is stopped on the roadside or is involved in a breakdown, drivers rely on the hazard lamps to alert oncoming traffic to their presence, even if the vehicle's ignition is turned off. This feature ensures that the hazard lights can be utilized without needing the engine to be running, which is especially important in emergency scenarios where the vehicle's power may not be available.

This function aligns with safety regulations and standards that require vehicles to have a reliable way to warn other motorists of potential hazards, regardless of the state of the vehicle's ignition. It is essential for ensuring that vehicles remain visible to other drivers, thereby reducing the risk of accidents.
