Did the driver properly secure the car before leaving it?

The video shows the driver removing the key from the ignition and applying the parking brake (handbrake), which protects the vehicle from moving on its own. According to Art. 46 para. 5 of the Road Traffic Act, the driver is obliged, during a stop, to secure the vehicle against its start-up by an unauthorized person and to take the necessary precautions to avoid an accident. The driver's actions demonstrate proper vehicle securing.
