Why is it necessary to inspect the headlights during the pre-trip?

Inspecting the headlights during the pre-trip is essential primarily to ensure visibility during night travel and adverse weather conditions. Adequate lighting is critical for the safe operation of the vehicle, allowing the driver to see the road, other vehicles, and pedestrians clearly. This visibility becomes even more vital when driving in adverse conditions such as rain, fog, or snow, where natural light is diminished, making it harder to navigate safely.

Proper functioning headlights not only help the driver see but also enable others on the road to see the vehicle, reducing the risk of accidents. Thus, ensuring that headlights are working effectively addresses safety concerns directly linked to night-time driving and inclement weather.
