Iran on a US Licence (2026): IDP Needed, Driving Discouraged

Before the road rules, one note that overrides them: US citizens face significant travel restrictions and entry hurdles for Iran, so check the State Department’s current advice for the country first. This page assumes you have done that and want to know what the road holds.

The permit question

Many readers land here asking about an international drivers permit for Iran, and the State Department answers it in a single sentence: travelers in possession of International Driver’s Permits may drive in Iran, though the Foreign Interests Section in Iran does not recommend that tourists do so. So a US licence needs an IDP beside it, obtained from AAA or AATA before you leave, and the official US view is that you would be better off not driving at all. Hiring a car with a driver is the safer reading of that advice.

What the State Department says about the roads

The department describes a very high rate of traffic accidents, the second highest cause of mortality in the country. Its list of habits to expect is specific:

• Drivers throughout Iran tend to ignore traffic lights, traffic signs and lane markers.
• Urban streets are not well lit, so driving at night is particularly dangerous.
• Sidewalks exist only on main roads and are usually blocked by parked cars; in residential areas there are few.
• Drivers almost never yield to pedestrians at crosswalks.

Two instructions matter for foreigners. If you are in an accident, no matter how minor, do not leave the scene; wait for the police to file a report. And authorities sometimes set up informal roadblocks in cities and on highways, often staffed by young, inexperienced officers who are suspicious of foreigners. Carry identification and avoid disputes.

Alcohol is not a grey area

Alcohol is prohibited in Iran, so the American habit of thinking in terms of a 0.08 limit has no use here. If you are driving, there is no safe amount to consider.

Limits in mph

Iran drives on the right, as the US does. Speeds are posted in kilometres per hour:

The motorway figure is roughly the US interstate norm, so speed is rarely the issue. Anticipation is: in Tehran, lane markings read as suggestions, merging is assertive and motorcycles fill every gap.

Tehran and everywhere else

The State Department’s wording is that drivers tend to ignore lights, signs and lane markers, so assume the car beside you will not follow them. Pedestrians have little protection, since drivers almost never yield at crosswalks and sidewalks are blocked by parked cars. If you must drive, keep to daylight, choose a car with a driver for the city, and use your own wheel only on open roads where your attention can stay on the vehicle ahead. Keep your passport and the IDP together, and carry a copy of both, because roadblocks can ask for identification at any time.

Kit, age and numbers

Our record lists a warning triangle, first-aid kit and fire extinguisher as required equipment in Iran, with no reflective vest. At home all of these are only recommended, so check that a rental or borrowed car carries them. The minimum driving age for a car is 18, two years above the 16 common in the United States.

The emergency numbers differ from the American 911: 110 for police, 115 for an ambulance and 125 for the fire service. Mobile coverage and mapping apps can be unreliable for visitors, so download offline maps before you leave home.

Detailed enforcement for tourists is not well documented, and the wider travel context matters more here than almost anywhere, so plan conservatively. See the Iran driving guide, the Driving Permit Checker for other countries, and how driving fines abroad work and who pays.
