What must be verified regarding the headlights during the pre-trip inspection?

During the pre-trip inspection, it is essential to verify that the headlights are operational and properly aimed. This is crucial for several reasons. First, operational headlights ensure that the driver can see the road clearly during nighttime or low visibility conditions, contributing to safety. If the headlights are not working, the driver may not be able to see obstacles, road signs, or other vehicles, increasing the risk of accidents.

Proper aiming of the headlights is equally important, as misaligned headlights can either blind oncoming drivers or fail to adequately illuminate the road ahead. If headlights are aimed too high, they can create glare for other drivers, leading to dangerous situations. Conversely, if they are aimed too low, they may not provide sufficient illumination for the driver, limiting their ability to navigate safely.

Overall, verifying that headlights are both operational and properly aimed is a critical safety check that ensures the vehicle is safe for operation and helps prevent potential accidents caused by inadequate lighting.
