To safely support a vehicle after lifting with a floor jack, you should always use

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

Answer: (C)

After lifting a vehicle with a floor jack, you must support the weight with jack stands. Jack stands are built to bear the vehicle’s load securely and to distribute it across solid points, giving you a stable, fixed support while you work. Relying on the floor jack alone is unsafe because jacks can fail or sink, causing the car to drop unexpectedly.

Wheel chocks are important to prevent the vehicle from rolling, but they don’t carry the weight. Lug nuts secure a wheel to the hub and aren’t designed to support a raised vehicle. A base plate helps some jacks stabilize on soft surfaces, but it isn’t a substitute for proper support under the vehicle.

For safety, place the vehicle on stands on a level surface, under the recommended support points, then carefully lower the jack to transfer the load to the stands before you go underneath.
