What is a hazard if the tire jack fails during a change?

• A. If the jack fails, the operator can be crushed
• B. The tire will explode
• C. The engine will stall
• D. The battery will drain

Answer: (A)

When you lift a car to change a tire, the focus is on how a lifting device can fail and what that means for safety. If the jack gives way or sinks, the vehicle can drop suddenly onto the person nearby. That rapid descent can crush or severely injure anyone underneath or beside the car. Because of this, the safest practice isn’t to rely on the jack alone—you use it on a flat, solid surface, chock the wheels, and place sturdy supports like jack stands before you go under or remove a tire. The other listed outcomes—tire exploding, the engine stalling, or the battery draining—don’t stem from the jack failing, so they aren’t the hazards at play here. The real danger is crush injuries from the vehicle dropping if the jack fails.
