When must you use your headlights while driving a commercial vehicle?

Using your headlights from sunset to sunrise and in poor visibility conditions is essential for maintaining safety on the road, especially when driving a commercial vehicle. This requirement ensures that other drivers and pedestrians can see you and that you have adequate visibility to navigate safely. Poor visibility conditions can include fog, heavy rain, snow, and any other circumstances where your ability to see or be seen is compromised.

Headlight use during these times is not just a matter of legal compliance; it is a critical safety measure that helps prevent accidents. While it is also important to use headlights during specific weather conditions, relying solely on daylight may not be sufficient in all scenarios, which is why this choice emphasizes both time and visibility conditions for safe driving.
