When should headlights be used?

Headlights should be used in various conditions to ensure safety on the road. While using them only at night is common, it is important to recognize their utility in adverse weather conditions such as rain, fog, or snow. In these situations, headlights improve visibility not only for the driver but also for other road users who might have difficulty seeing the vehicle due to poor weather conditions.

Additionally, using headlights during the day can enhance safety by making vehicles more visible to other drivers, especially in low-light situations or when driving through areas where visibility may be compromised. This practice aligns with the principle of being proactive about safety, reducing the risk of accidents.

Therefore, the most comprehensive answer acknowledges that headlights should be used in both adverse weather conditions and during the day for safety purposes, making the correct choice one that fully covers these important aspects of safe driving practices.
