In what situation is it mandatory to have your vehicle's headlights on?

Having your vehicle's headlights on during times of reduced visibility or in bad weather conditions is essential for safety and legal compliance. This requirement applies regardless of the time of day because poor visibility could be due to various factors, such as fog, rain, snow, or even heavy cloud cover. Headlights help illuminate the road and make your vehicle more visible to other drivers, which is crucial for preventing accidents.

While it's true that headlights are mandatory during nighttime, the law also emphasizes their use in conditions where visibility is compromised, which is why this option is the most comprehensive. Driving in residential areas or while following another vehicle does not automatically necessitate the use of headlights unless visibility is also reduced. Thus, the importance of headlights in adverse conditions emphasizes their role in enhancing road safety at all times.
