What must you do before setting off on a journey?

Your answer is entirely correct because it involves crucial safety checks that are required before embarking on a journey, especially with a motorcycle.

1. Checking the road safety and operational safety of the motorcycle ensures that the vehicle is in good working order, crucial for safe driving as per the German Road Traffic Regulations (StVO).
2. Checking the helmet visor and snug-fitting clothing is vital for personal safety, as adequate protective gear reduces the risk of injury in the event of an accident, which is emphasized in traffic laws.
3. Ensuring that panniers and the top case are fixed correctly is important for vehicle stability and safety during travel, preventing any loss of cargo or hazards on the road.

These steps collectively enhance not only your safety but also that of other road users, which is a significant focus of traffic regulations in Germany.
