Is it legal to use your fog lights during clear conditions?

Using fog lights is specifically intended to enhance visibility in poor weather conditions such as fog, heavy rain, or snow. They are designed to produce a wide, low beam of light that reduces the amount of light that is reflected back at the driver by fog or precipitation. In clear conditions, using fog lights can create unnecessary glare for other drivers and can be distracting, which poses a safety risk on the road.

Legal regulations often dictate that fog lights should not be used under clear conditions unless specified by law, as their purpose is not to improve visibility during normal driving situations. This ensures that all drivers maintain a clear and safe line of sight without the interference caused by improperly used auxiliary lighting. Therefore, it is not permissible to use fog lights in clear conditions, which makes this answer the correct choice.
