Oman’s paved roads can take a visitor from Muscat to Nizwa and Sur in a normal car. Mountain checkpoints, desert tracks and flooded wadis create a clear boundary where the vehicle, weather or rental contract may require another plan.
This Oman rental car guide covers visitor licences, 4WD limits, mountain fog, flash floods and return records. Begin with the driving in Oman overview for national rules. The seven-day mountains and desert route keeps off-road driving outside the default itinerary.
Confirm licence acceptance with the branch
Royal Oman Police states that a visitor can use a home-country licence while holding a visit visa valid for three months. Rental companies can apply narrower rules based on the issuing country, language, vehicle and insurer.
Send the branch a copy of the licence details before booking and ask whether it also requires an International Driving Permit. Bring the originals, passport and payment card named in the reservation.
Register every driver
Each driver should appear on the contract and meet the company’s age and experience conditions. Ask how an additional driver changes roadside assistance and damage protection.
Keep the rental agreement, registration and insurance contact available offline. Police may ask to see the licence or vehicle documents.
Check border permission separately
Driving toward the UAE or another country needs written rental permission, insurance and border documents. A road on the map does not extend the domestic contract.
Inspect tyres, cooling and supplies
Photograph the body, wheels, windscreen, mileage and fuel level. Check tyre pressure, tread, spare or repair kit, jack and warning triangle with the agent.
Test the air conditioning and phone charging. Carry water for passengers and keep it shaded, but do not treat bottled water as a substitute for a safe desert plan.
Ask what roadside assistance covers
Confirm whether assistance applies on unpaved roads, mountain routes and remote areas. Save the company’s accident and breakdown numbers.
The contract may exclude sand, wadis and tracks even when the vehicle has four-wheel drive. Written terms govern the rental.
Refuel before remote stages
Use a known station while the correct fuel grade and payment can be checked. Do not wait for the reserve warning before a mountain or desert transfer.
Keep 4WD as a vehicle rule
Experience Oman’s general guidance calls for four-wheel drive on off-road travel and recommends GPS, safety equipment, supplies and more than one vehicle for desert travel. A 4WD badge does not make a solo sand crossing safe.
Use a licensed guide or camp transfer for dunes unless the driver has the equipment, training, companion vehicle and contractual permission. Meet at a paved or agreed access point.
Check mountain access before climbing
Some mountain roads and checkpoints restrict unsuitable vehicles. Ask the lodging and rental company whether the assigned car qualifies for the exact approach.
Fog can reduce visibility at elevation. Experience Oman’s activity guidance advises using lights in mountain fog.
Descend in a suitable gear
Control speed before a bend and use engine braking on long descents. Stop at a marked area if the brakes smell hot or the driver loses concentration.
Stay out of flowing water
A dry wadi can flood after rain falls upstream. Check forecasts and official warnings for the whole catchment; the sky above the car is too narrow a signal.
Do not cross moving water, drive around a closure or park in a channel. Turn back and wait on higher ground when water reaches the road.
Move the plan before the storm
Replace a wadi day with a city, fort or coastal stop when rain is forecast. A booked hotel is easier to change than a vehicle trapped between crossings.
Use the mountain driving guide for visibility and descent routines.
Tell the lodging your route
Share the planned arrival time on remote stages. Contact the property from the last town when a delay or route change develops.
Park from the local sign
Muscat, Nizwa and Sur have broad roads alongside compact market and waterfront areas. Set a public car park or hotel vehicle gate as the destination.
Read signs for reserved spaces, time restrictions and events. Do not block shop access, mosque entrances or private gates.
Protect the car from heat
Take passengers and animals out of a parked vehicle. Keep electronics and pressurised items away from direct sun.
Photograph the bay and sign when a parking restriction is unclear. Ask the lodging before leaving the car overnight.
Return with sand documented
Use an approved wash if the contract requires it and allow time for inspection. Photograph the final panels, glass, tyres, mileage and fuel level.
Sources and review date
Visitor-licence duration was reviewed on August 17, 2026 using the Royal Oman Police FAQ. Traffic, document and dangerous-driving offences were checked with the ROP traffic service. Off-road, desert and supply guidance was checked with Experience Oman’s general guidelines, while mountain-fog advice was checked with its activities booklet. Confirm licence acceptance, vehicle access and weather before each stage.
