When is it mandatory to turn on your vehicle headlights?

Turning on your vehicle headlights is mandatory from sunset to sunrise to ensure visibility and safety during times when natural light is diminished. This rule helps drivers see the road and its surroundings clearly, as well as making their vehicle more visible to other road users, which is critical in preventing accidents during low-light conditions.

Using headlights during these times is not just about personal safety; it's also a legal requirement in New Zealand, intended to protect all road users. While headlights are also important in adverse weather conditions like rain or fog, the specific rule mandates their use during the designated nighttime hours. This helps to standardize driver behavior and promotes consistent and safe driving practices.
