Should You Use Fog Lights or Hazard Lights in Heavy Rain?

[StMiranda]

Whether to use fog lights or hazard lights in rainy weather primarily depends on visibility. When visibility is less than 200 meters, turn on the fog lights along with regular lights; when visibility drops below 100 meters, activate the hazard warning flashers (also known as hazard lights). Function of fog lights: Front fog lights are designed to improve illumination in unclear road conditions ahead, providing a high-intensity scattered light source that penetrates thick fog to alert oncoming drivers. Rear fog lights are installed at the rear of the vehicle to ensure visibility for other road users behind in low-visibility conditions such as fog, snow, or heavy rain, emitting a stronger light than tail lights. Function of hazard warning flashers: Hazard warning flashers serve as signal lights to alert other vehicles and pedestrians that the vehicle is experiencing special circumstances. They should be activated in situations such as vehicle breakdowns on highways, high-speed driving, temporary parking on roads, towing a malfunctioning vehicle, encountering an emergency while driving, being involved in a traffic accident, or when performing special tasks.
