When should headlights be used?

Headlights should be used in low visibility conditions to enhance safety on the road. This includes situations such as fog, rain, or snowfall where visibility is compromised. Utilizing headlights in these circumstances allows other drivers to see your vehicle more clearly, reducing the risk of accidents.

Headlights are not solely limited to nighttime driving; they are essential whenever visibility is low. While heavy traffic can suggest the need for increased awareness, it does not inherently necessitate the use of headlights unless conditions dictate otherwise. Parking also does not typically require headlights unless specified by local regulations to indicate the vehicle's presence. Thus, the primary role of headlights in low visibility conditions makes it the most appropriate choice for when they should be used.
