Important rules
- F-roads always require 4x4 — insurance doesn't cover driving an F-road with a normal car.
- Gravel roads can damage windshield and paint — drive carefully and keep right distance.
- Roads close in winter — always check road.is before you go.
- River fords on F-roads can be deep and strong — assess conditions before crossing.
