Don't drive cross-country (and certainly not across a knee-high, flowering organic meadow, and OBVIOUSLY not side-by-side!).
Be considerate and give right of way. Announce your passing well in advance so as not to frighten other road users.
Reduce your speed when overtaking and crossing, stop if necessary. (Ringing is an advantage, calling is also possible).
Be considerate of animals, their habitats and active times. Avoid driving at dusk and in the dark. If you see an animal, stop and wait until it has moved to safety.
If possible, do not brake with locked wheels. Avoid trails after heavy rainfall. Both favor earth erosion. Of course, take your waste home with you!
Drive concentrated & kontrolliert. Du musst in Sichtweite anhalten können, passe also deine Geschwindigkeit dementsprechend an.
From head to toe and of course your bike! For your own safety, always wear a helmet, gloves if necessary and protectors.
Find out in advance about the area you are driving in, take a map and/or your smartphone for orientation.
