You are driving an agricultural tractor emerging from an unpaved field path (Feldweg) onto an asphalt public road where no traffic signs are posted. Who has right of way?

1. You have priority because you are coming from the right (standard right-before-left rule)
2. You have priority because agricultural vehicles always outrank passenger cars
3. Vehicles must stop and negotiate priority through hand signals
4. Traffic on the paved public road has priority; you must yield before entering the road (StVO § 19 Abs. 6)
