Name one of the key components checked during a pre-trip inspection.

During a pre-trip inspection, checking the brakes is critical to ensuring vehicle safety. The braking system is essential for controlling the vehicle and is one of the most important safety components. This inspection typically involves verifying that the brake lights are functional, the brake pads and shoes are in good condition, checking for air leaks in air brakes, and ensuring that the brake fluid levels are appropriate. These checks help prevent accidents caused by brake failures, which can occur if the system is compromised.

While the other components such as the radio, dashboard lights, and seat adjustments are important for driver comfort and vehicle functionality, they do not directly impact the vehicle's ability to stop safely, making the brakes a top priority during safety inspections.
