You have finished working in the fields and want to drive home on public roads with your tractor. It is already dusk. What must you do?

Your selected combination is correct and aligns with German traffic regulations regarding the use of vehicles on public roads during low visibility conditions.

According to German traffic laws, specifically the Road Traffic Regulations (StVO), it is mandatory to use vehicle lights when visibility is limited, such as during dusk. This ensures that you are visible to other road users, enhancing safety.

Additionally, checking your lights for functionality and cleanliness is crucial. Dirty or malfunctioning lights can greatly diminish your visibility to others, which can lead to accidents.

While switching on work lights can provide additional visibility, it is not always a requirement unless specified for certain types of vehicles or situations, making it less critical compared to the other two choices.

Thus, ensuring to switch on your regular lights and checking their condition is essential for safe driving in low light.
