How many performance stops are required during a pre-trip inspection?

The requirement for three performance stops during a pre-trip inspection is based on ensuring the safety and reliability of the vehicle before it is put into service. Each performance stop serves a specific purpose in evaluating the vehicle's operation and readiness.

The first performance stop typically includes checking the vehicle's brakes to ensure they are responsive and functioning correctly, which is crucial for safe operation. The second performance stop may involve assessing signals and lights, ensuring proper visibility and communication with other road users. The third performance stop often includes evaluating steering and suspension to confirm the vehicle handles as expected.

This thorough process helps pinpoint potential issues that could affect performance while driving, ultimately enhancing both safety for the driver and passengers, as well as compliance with transportation regulations. Ensuring these three performance checks are completed helps instill confidence in the vehicle's operational status.
