At what distance must you turn on your vehicle's headlights before sunset?

The correct answer is that you must turn on your vehicle's headlights one-half hour before sunset. This rule helps ensure that you are visible to other drivers as daylight begins to fade, improving safety on the road. By activating your headlights early, you not only adhere to the legal requirements but also enhance your ability to see and be seen in low-light conditions.

This regulation is in place because visibility can diminish significantly even before the sun sets completely, making it crucial to have your headlights on in advance. This helps in reducing the risk of accidents during transitional lighting conditions. It's also important to be aware that other drivers may not see your vehicle as easily in dusk light; therefore, being proactive by using your headlights can improve overall roadway safety.
