What is the correct way to handle driving behind a slow-moving agricultural tractor on a narrow winding road with solid centre lines?

1. Remain patient behind the tractor at a safe following distance until a broken centre line with clear forward visibility appears, and overtake only when completely safe
2. Cross the solid centre line on a blind corner to pass the tractor
3. Honk aggressively and drive on the left ditch
4. Push the tractor with your vehicle front bumper
