Why should jack stands be used during vehicle repairs?

Using jack stands during vehicle repairs is essential primarily for safety. When a vehicle is lifted using a jack, it may become unstable if the jack fails or if the vehicle shifts. Jack stands provide stable support, preventing the vehicle from falling and potentially causing serious injury to the technician working underneath.

While other factors such as efficiency and access do play a role in performing repairs, safety is paramount. Jack stands ensure that the vehicle stays securely in place, offering a much higher level of protection for anyone working underneath the car. Proper use of jack stands significantly reduces the risk of accidents that can occur from unexpected vehicle movement, making them a crucial tool in any maintenance or repair situation.
