What is the maximum height at which fog lights should be mounted?

Fog lights should be mounted at a maximum height of 30 inches from the ground. This regulation is in place to ensure that fog lights effectively illuminate the road immediately in front of a vehicle without causing glare to oncoming drivers. Fog lights are designed to shine a wide and low beam of light which reduces the amount of light that reflects off fog, rain, or snow back into the driver's eyes, improving visibility. If fog lights are mounted higher than this specified height, they can potentially shine into the eyes of other drivers and create hazardous conditions instead of improving safety.
