What should be checked regarding the lights on the vehicle?

The requirement for checking the lights on the vehicle during a pre-trip inspection is comprehensive and includes ensuring that all lights are functioning properly and are free of damage. This encompasses headlights, tail lights, brake lights, turn signals, and side marker lights. Properly functioning lights are critical for visibility and communication with other drivers on the road, especially in low-light conditions or adverse weather. Damaged lights can reduce visibility and may lead to violations or accidents.

Inspecting only the headlights, disregarding tail lights, or considering side lights as optional would lead to significant safety risks and potential legal issues. Each type of light plays a vital role in ensuring safety, as they help other drivers see your vehicle and understand your intentions, such as stopping or changing lanes. Thus, it is essential to conduct a thorough check of all vehicle lights to ensure they are in perfect working condition.
