In BC, when are you required to use headlights?

The requirement to use headlights in British Columbia is specifically from half an hour before sunset to half an hour after sunrise. This regulation ensures that drivers remain visible during low-light conditions, which helps prevent accidents and enhances safety on the road. Using headlights during this time makes it easier for other vehicles and pedestrians to see you, reducing the risk of collisions.

The rationale for this rule is tied to visibility. During dawn and dusk, the natural light can be quite dim, and headlights help to illuminate the road and make vehicles more noticeable. This period is critical for safety, particularly when transitioning from day to night or vice versa.

In contrast, the alternatives provided suggest using headlights at different times or conditions that do not encompass all necessary scenarios for safe driving. For instance, using headlights only during heavy rain or at night omits the important transitional times when visibility may still be compromised. Therefore, the correct understanding centers around using headlights during the specified times to maximize road safety.
