When should fog lights be used?

Using fog lights is appropriate when visibility is significantly reduced, specifically to 100 meters or less. Fog lights are designed to illuminate the road directly in front of the vehicle in conditions where other lights may create glare or be less effective, such as during fog, heavy rain, or snow. In these circumstances, the light from standard headlights reflects off the moisture in the air, hindering clarity rather than enhancing it. Fog lights emit a low, wide beam of light that is positioned closer to the ground and helps drivers see the edges of the road and other obstacles more clearly.

It's important to recognize the specific conditions that warrant the use of fog lights for safety reasons, and utilizing them at the appropriate times contributes to better visibility and reduces the risk of accidents in low visibility situations.
