These headline prices change with date, length and company. They exclude zero-excess insurance, fuel and extras (child seat, second driver). Comparing several companies online helps you see the total price, deposit, excess and cancellation terms before you pay, but it guarantees no price.

Where to pick up the car

Chiang Mai airport (CNX) is the most convenient starting point: pick-up is at the terminal, and the road south (Doi Inthanon) or north (Pai, Chiang Rai) avoids the old city. If you arrive by night train or by bus and plane, rent the next day after a good night's sleep: don't get behind the wheel tired in a city where traffic keeps left.

Deposit, excess and insurance

  • Deposit: usually blocked on a credit card in the main driver's name. Ask for the exact amount before booking; it varies by company and vehicle.
  • Excess: basic damage cover leaves an excess for you to pay. "Zero-excess" insurance costs extra per day and is useful on mountain roads, where a scratch or a damaged tyre happens easily.
  • Exclusions: tyres, windscreen, underbody, lost keys, unpaved tracks, alcohol and driving without a valid licence. Read them: drivers without a proper international permit risk having a claim refused. Details in international driving permit in Thailand.
  • Condition report: photograph the car from every angle, plus the odometer and fuel gauge, at pick-up and return.
  • Cancellation: some offers are free to cancel until a given date; check it.

Driving in Chiang Mai

  • Keep left, steering wheel on the right. Roundabouts, U-turns and scooters weaving on both sides are confusing for the first hour.
  • Old city: one-way streets, narrow lanes, little parking. Park at the hotel or in a car park, then walk or take Grab.
  • Mountains: paved but very winding roads with steep gradients; drive by day, use engine braking, and don't overtake on bends.
  • Night and rain: little lighting, animals and slow vehicles. Avoid driving in the mountains at dusk.
  • Speed and alcohol: obey the signs, and don't drive after drinking. For general rules, see laws and fines in Thailand.

Fuel and parking

Petrol stations are frequent on main roads, rarer in remote valleys: fill up before leaving Pai or Mae Sariang. An attendant serves you and you pay in cash or by card. Shopping centres have car parks, often free with a purchase; on the street, respect the red-and-white kerbs (no parking).

The three trips that justify a car

  • Doi Inthanon (2,565 m, Thailand's highest peak): about a day round trip from Chiang Mai, paved road. Without a car, compare outings in Doi Inthanon from Chiang Mai.
  • Mae Hong Son loop: about 600 km according to most sources, to be done in 4 to 7 days. A car is safer than a scooter in the rain; stages and scooter details are in renting a scooter in Chiang Mai. We give no number of bends: no official source confirms one.
  • Chiang Rai and the White Temple: a long day by car, or an organised trip without driving in the White Temple from Chiang Mai.

When a car isn't worth it

  • Short stay (1 to 2 days) or only the old city: Grab, songthaew or a private driver cost less and are safer.
  • Burning season (usually February to April): the air in the north is badly degraded, and driving for hours on mountain roads with poor visibility is no fun; see the best time to visit.
  • Inexperienced driver, or never driven on the left: choose a driver or an organised trip.
  • No international permit: you drive without valid insurance, so don't rent.
  • Solo, for a single excursion: a group trip is often cheaper than the car, fuel and insurance.

If you have an accident

On the spot: get to safety, switch on the hazard lights, check for injuries and call emergency services (191 (police), 1669 (ambulance), 1155 (tourist police)). Get a written police report on the spot: without it, the rental company and the insurer may refuse to pay. Photograph the vehicles, the plate, the road and the damage, note the other driver's details, and call the rental company before any repair.

Who pays what: damage to the car is covered by the rental company's protection (CDW), subject to its excess (deductible), or by an excess cover bought with the rental; injuries and medical costs fall under your travel insurance. Travel insurance does not pay for the rental car or for damage to third parties.

SafetyWing covers medical costs after an accident abroad; check the policy's conditions for driving (a licence valid in the country, a helmet on a scooter).
