Hazard lights, also known as emergency flashers, are a vehicle's warning lights that indicate a temporary hazard or emergency situation. When activated, they cause all turn signal lights to blink simultaneously, alerting other drivers that the vehicle is stationary or moving slowly due to an issue. This feature is commonly used during breakdowns, accidents, or when a driver needs to stop unexpectedly. To activate hazard lights, drivers typically press a button marked with a triangle symbol, usually located on the dashboard. Using hazard lights is important for safety, as it helps prevent accidents by making the vehicle more visible to other road users, including pedestrians and cyclists.
