Gravel & F-roads
The surface changes fast in Iceland, and F-roads are a different world that needs the right car — and the right insurance.
Where tarmac becomes gravel
The paved-to-gravel transition is where many rentals spin out. Slow right down at the change, avoid harsh steering, and treat gravel like a low-grip surface.

Brake early. Cross straight.
Make the speed change while the tires are still on tarmac. Hold a steady line across the seam, then keep every input gentle on the loose surface.

- Stay smooth

- 2Reduce speed while still on tarmac.
- 3Keep the wheel steady across the seam.
- 4Continue gently on the lower-grip gravel.
The transition is the danger: do not wait for the loose surface to slow down, and avoid harsh steering once the tires reach gravel.
F-roads need a 4x4
Roads numbered with an F (e.g. F35) are highland mountain tracks, often with unbridged river crossings. They legally require a 4WD vehicle, are closed in winter, and standard rental insurance usually does not cover them.
