Practice question

What is the primary purpose of wheel chocks?

  1. To prevent accidental vehicle movement
  2. To slow down the car
  3. To improve aerodynamics
  4. To assist with steering

Answer: A — To prevent accidental vehicle movement

Wheel chocks are used to prevent a vehicle from moving unintentionally. By wedging against a wheel and the ground, they create friction that stops the wheel from rolling, which is crucial when parked on a slope or when someone is working around the vehicle. This safety purpose helps avoid roll-away incidents that can cause injuries or damage. They’re not meant to slow the car, improve aerodynamics, or assist with steering, which is why the other options don’t fit.
