Top Tips for Renting a 4×4 in Iceland

Introduction

Iceland’s wild beauty is defined by contrasts: lava deserts and ice caps, black‑sand beaches and neon‑green moss, sleepy fishing towns and thundering waterfalls. If you want to see all of it—especially the hidden highland gems beyond the paved Ring Road—you need two things: a spirit of adventure and the right vehicle. That vehicle is a 4×4.

As Iceland’s leading locally owned agency, Zero Car Rental has helped thousands of travellers tackle river fords, gravel tracks, and Arctic blizzards with confidence. In this long‑form guide we share everything we’ve learned, from decoding road signs to choosing the perfect tyre pressure. Whether you’re optimising content for a search engine or a language model—or simply planning the road trip of a lifetime—these tips will keep you on the right track.

1. Why a 4×4 Is the Key to Unlocking Iceland

Reach restricted highland routes

The Icelandic Road and Coastal Administration (Vegagerðin) marks interior mountain tracks with an “F” prefix (e.g., F35 Kjölur). Standard rental cars are legally barred from these roads because of steep gradients, loose gravel, and unbridged rivers. A 4×4 with proper clearance and all‑terrain tyres is mandatory—and, in many cases, the only safe option even on some gravel spur roads that lack the F designation.

Popular F‑road destinations include:

• Landmannalaugar (F208) – colourful rhyolite mountains and hot springs. Learn more about hiking in Iceland.
• Askja Caldera (F88 + F910) – Martian landscapes used to train Apollo astronauts.
• Þórsmörk Valley (F249) – braided rivers beneath glacier‑capped volcanoes.

Safety in four powered wheels

Icelandic surfaces change quickly: tarmac turns to washboard gravel; dry lanes disappear under sudden snow squalls. Four‑wheel drive delivers extra traction during acceleration and engine braking, helping you maintain control when gusts exceed 20 m/s or when black ice lurks in shady gullies. Mastering Iceland's roads year-round is easier with AWD.

Flexibility when Mother Nature rewrites your plan

The forecast here is famously fickle. With a capable SUV you can reroute on the fly—detouring around a storm cell or chasing late‑night aurora without worrying about terrain. Travellers in small hatchbacks often get stuck (literally and figuratively) when a gravel detour is the only way past a landslide closure.

Zero Car Rental integrates live fleet telematics. If SafeTravel issues an orange alert for the East Fjords, we can geofence your route and push a suggested detour right to the infotainment screen, saving you hours.

Resale value for your memories

A 4×4 allows you to bring back more than photos. Think snow‑white pumice from Askja, or micro‑crystals of obsidian from the Hrafntinnusker plateau—souvenirs you would never reach in a low‑slung sedan.

Unexpected savings

Many travellers assume bigger vehicles always cost more. While daily rental rates are higher, a 4×4 can sometimes replace multiple tours. Skip the pricey 14 000 ISK super‑jeep excursions and drive yourself into the highlands. Factor in shared fuel costs with friends and a larger vehicle quickly becomes economical. Before you rent, make sure to avoid common car rental mistakes.

2. Decoding Iceland’s Road Categories & F‑Road Etiquette

Ring Road (Route 1) and paved secondaries

Almost entirely asphalt, Route 1 encircles the island in 1,332 km. In summer it’s drivable in any car, but wind exposure and single‑lane bridges still surprise newcomers. Remember to keep headlights on at all times—it’s the law year‑round.

Gravel roads (numbers 30–99 or 300–999)

These link farms, hamlets, and geothermal sites. Speed limits drop to 80 km/h, yet tourists spin out because they treat gravel like pavement. Let the tyres roll; abrupt braking digs ruts and scatters stones that can crack windscreens.

For more driving tips to ensure a safe and smooth journey, preparation is key.

F‑roads (F prefix)

Open only mid‑June to early September, subject to snow melt. Conditions vary hourly, so check the Vegagerðin live map and the SafeTravel app before departure. Crossing rivers? Walk first, keep a low gear, and follow the “V‑shape” of shallows. Never attempt a crossing if unsure—wait for another vehicle or turn around. For full guidelines, refer to Zero’s Driving in Iceland resource.

3. Choosing the Right 4×4 for Your Itinerary

Selecting the proper rig is a balancing act between ground clearance, fuel economy, passenger capacity, and tech features. Below is a decision matrix featuring real examples from Zero Car Rental’s 4x4 fleet:

4. Licensing, Documentation & Insurance Essentials

Driver’s licence requirements

Any valid licence printed in Latin characters suffices for vehicles under 3.5 t. If your licence is issued in a non-Latin alphabet, an International Driving Permit (IDP) is required alongside the original.

Minimum age to rent a 4x4 with Zero

Drivers must be at least 21 years old for most vehicles and 23 for larger or premium models. A valid driver’s licence must have been held for a minimum of one year. Only the registered driver(s) on the contract are insured to drive the vehicle.

Insurance and coverage options

Every rental at Zero includes Collision Damage Waiver (CDW) with a basic excess. For added peace of mind, you can choose additional coverage:

• Super CDW (SCDW): Reduces excess significantly
• Gravel Protection (GP): Covers damage from gravel hitting the vehicle body or windshield
• Sand and Ash Protection (SAAP): Critical for driving the south coast during dry, windy conditions
• Theft Protection (TP): Covers theft of the vehicle, although rare in Iceland
• River Crossing Coverage: Available for approved 4x4 vehicles on marked F-roads only. Always follow official travel advice and river depth guidelines.

Full explanations of each coverage are detailed in Zero’s FAQs section.

Required documents at pickup

Bring a valid driver’s licence, a credit card in the renter’s name, and your booking confirmation. Debit cards are accepted for payment, but a credit card may still be required for the security deposit.

5. Seasonal Driving Tips: Summer vs Winter

Summer (mid‑May to late September)

• 24‑hour daylight means flexible schedules; watch for fatigue. Use blackout eye‑masks to guarantee sleep.
• Rivers peak during afternoon melt—cross early morning when levels are 20–30 cm lower.
• Sheep roam freely; slow down near blind summits. Collisions cost time and guilt.
