Driving Requirements
Thai law allows tourists to drive on a valid foreign license for up to 60 days from the date of entry. An International Driving Permit (IDP) is not required by law but is strongly recommended as rental companies and police checkpoints often request it alongside your home license.
The legal minimum driving age in Thailand is 18. However, rental companies set their own policies - most require drivers to be at least 21, with some premium vehicles requiring 23 or 25. Young driver surcharges may apply for those under 25.
Thai law requires all vehicles to have Compulsory Third Party Liability insurance (CTPL). Rental companies typically provide this basic coverage but offer additional Collision Damage Waiver (CDW) and theft protection as optional upgrades. Check what's included before signing.
Rental companies universally require a credit card in the driver's name for security deposit (amount varies by company and vehicle class). Debit cards are rarely accepted. The deposit is held (not charged) and released after vehicle return.
Thailand drives on the left side of the road. Key rules that surprise visitors: U-turns are allowed at designated U-turn slots only, motorbikes often drive between lanes, and at roundabouts, vehicles already in the circle have right of way. Red lights mean complete stop - no right turn on red.
Helpful Tips
Pick up at Chiang Mai International Airport (CNX) for the widest fleet and 24-hour desks. But expect a 10, 15 % surcharge; city-center offices on Huay Kaew and Nimman roads often waive one-way drop fees if you return to the same location.
Walk around the car and photograph every panel, alloy wheel, and the odometer with your phone. Most Chiang Mai agencies accept these date-stamped images if you dispute scratches on return. But CDW from Thai insurers still carries a 8,000, 15,000 THB deductible unless you buy the zero-excess add-on.
Google Maps works reliably in Chiang Mai province. But download the province offline before leaving Wi-Fi; Waze is faster for real-time police checkpoints, while't forget a vent-mount phone holder, dashboard mounts are illegal.
All rentals use 91 or 95 octane petrol. Stations are plentiful on the superhighway ring and along Huay Kaew Road, and almost every agency operates on a full-to-full policy, return with a receipt from PTT or Bangchak within 5 km of the depot to avoid refueling surcharges.
Inside the old city moat, expect 20, 40 THB/hour curb-side meters until 20:00 and tight lanes; Nimman and the Night Bazaar have guarded hotel or mall garages that charge 50, 100 THB overnight, while guesthouses outside the walls usually offer free shaded parking on their own lots.
Driving Warnings
At the Nimmanhaemin, Huay Kaew intersection, right turns on red are strictly forbidden and cameras issue automatic fines.
During the burning season (roughly February, April), smoke haze on the Mae Rim and Samoeng roads can drop visibility to under 100 m and ash clogs air filters.
Expect gridlock on the Superhighway (Chiang Mai, Lampang Road) between 7, 9 a.m. and 4, 6 p.m.; the Wororot Market stretch is often the worst bottleneck.
Police set up frequent DUI checkpoints on the Night Bazaar section of Chang Khlan Road after 9 p.m.; refusal to take a breath test carries an immediate licence suspension.
