What is the correct sequence of operations for performance testing?

The correct sequence of operations for performance testing begins with the weight verification test, an essential initial step that ensures the vehicle's weight is within the manufacturer’s specified limits. This verification is crucial since weight impacts the vehicle's performance in various aspects, including braking and handling.

Following weight verification, the braking system test is conducted. This test evaluates the overall effectiveness of the vehicle's braking system, assessing components like the brake pads, rotors, and hydraulic systems to ensure they function properly under load.

Next in the sequence is the parking brake test, which specifically verifies that the parking brake can hold the vehicle stationary when engaged, an important safety feature when the vehicle is not in use.

Finally, the road test is performed. This step allows for the comprehensive evaluation of the vehicle's handling, braking efficiency, and overall performance in real-world driving conditions.

This logical progression—from weight verification through to practical testing on the road—ensures that all critical components and systems are evaluated systematically, enhancing safety and operational readiness.
