What is the first step in a pre-trip vehicle inspection?

The first step in a pre-trip vehicle inspection involves inspecting the external condition of the vehicle. This foundational step allows the driver to assess the overall condition of the truck or bus, identifying any visible issues that may affect safety or performance. By conducting a thorough external inspection, the driver can look for signs of damage, leaks, or obstructions that could pose hazards during operation.

Starting with the external condition also sets the stage for subsequent checks. Ensuring that the exterior of the vehicle is safe can prevent issues such as tire blowouts or mechanical failures, which could arise from unnoticed damage. Additionally, this assessment provides an opportunity to evaluate critical components that are visible without having to move into the more complex checks involving the inner workings of the vehicle, such as the brake system or lights.

Once the exterior condition is confirmed to be satisfactory, the driver can then proceed to check tire pressure, test the brake system, and ensure the lights are functioning correctly, all of which are essential for a safe trip.
