What must you do when leaving your car?

You correctly selected all required actions when leaving your car. According to German traffic rules, before opening the door, you must check for traffic behind to avoid endangering others. You need to make sure your vehicle is secured against rolling away—this means engaging the handbrake and possibly using gear or an automatic transmission’s park position. Lastly, the vehicle must be secured against unauthorized use, such as locking the doors and removing the key. By following all these steps, you help ensure safety and comply with regulations.
