When should you drive with your parking lights on?

You should use your parking lights when your vehicle is parked on the side of the road in low visibility conditions, such as during fog, heavy rain, or snow, to make your car more visible to other drivers. However, parking lights are not intended for use while driving, as they do not provide adequate illumination for safe driving. Always use your headlights when you are on the road, especially at night or in poor weather conditions.
