When using a floor jack, a technician should always use

• A. jack stands
• B. wheel chocks
• C. lug nuts
• D. jack handle

Answer: (A)

When a floor jack is used, the vehicle is only temporarily supported by hydraulic pressure. That means the jack can fail or settle, letting the car drop if you start working under it. The essential safety step is to place jack stands under solid, designated support points and lower the vehicle onto them. Jack stands provide stable, fixed support that won’t collapse or move as you work, allowing you to work safely underneath. Position them on a firm, level surface and near the same structural points recommended by the vehicle manufacturer, then slowly lower the car onto the stands and test for stability before you begin. For extra prevention of movement, wheel chocks on the wheels remaining on the ground can help, but the crucial safeguard is using jack stands to support the vehicle.
