You experience a breakdown outside of a built-up area. Your car is situated on the carriageway, behind a bend in the road. Which is correct in this situation?

You answered everything correctly. In the event of a breakdown outside a built-up area, especially if your vehicle is hidden behind a bend, you must switch on your hazard lights to warn approaching drivers. Placing a warning triangle at least 100 meters behind your vehicle gives other road users advance notice of the hazard, which is required by law. Additionally, wearing a hi-vis vest increases your own safety, making you more visible to traffic. These measures help prevent accidents and are all required or strongly recommended under German traffic regulations for emergencies on the road. Knowing and applying these steps will help you stay safe and comply with traffic laws in similar situations.
