You have to change the front-right wheel of your biaxial motor vehicle. You apply a wheel chock to prevent the vehicle from accidentally rolling off. What must you be aware of when doing so?

When changing the front-right wheel of a biaxial motor vehicle, it is important to secure the vehicle against rolling. According to German traffic rules, you should place the wheel chock on the wheel of the rear axle. This is because the rear wheels provide the most reliable support for preventing movement. Also, ensure the vehicle is positioned on the most stable ground possible to avoid any slipping or shifting. Placing the chock on the undamaged front wheel or other locations is less effective and does not guarantee that the vehicle will remain stationary. This practice helps avoid accidents during the wheel change.
