While you are travelling on the autobahn, your passengers tell you there is smoke in the bus. What must you do?

Your answer is correct because in case of smoke in the vehicle on the autobahn, safety is the top priority. You must stop immediately on the hard shoulder to prevent any danger to yourself and other road users. Securing the vehicle at a sufficient distance ensures other drivers can see and avoid your bus. Additionally, directing your passengers to a safe location away from the bus and the autobahn protects them from potential danger such as fire or accidents. Driving on to the next petrol station would be unsafe because the situation could worsen during the drive and endanger everyone on board and other road users. Always stop promptly and move everyone to safety first.
