Which of the following is NOT a recommended safety procedure for automotive lifts?

The choice that is identified as correct stands out because it goes against fundamental safety practices associated with using automotive lifts. Shaking the vehicle while it is at working height creates a hazardous scenario that could compromise the stability of the lift and the safety of individuals in the vicinity. Maintaining a stable working environment is crucial, as any unnecessary movement can lead to accidents or injuries.

In contrast, securing the vehicle with wheel chocks helps prevent it from rolling, ensuring that the vehicle remains in place while being serviced. Similarly, ensuring the vehicle's stability before beginning work is a standard safety measure that confirms the lift is functioning correctly and the vehicle is well-balanced. Regular inspection of lift mechanisms for wear is essential to maintain the equipment's integrity and operational safety over time. All of these practices are standard operating procedures aimed at minimizing risks associated with using automotive lifts.
