Driving Requirements
Thai law allows tourists to drive on a valid foreign license for up to 60 days. After that, a Thai license or IDP is required. An IDP must be carried alongside your home license and is valid for one year from issue.
The legal minimum age to drive any car in Thailand is 18. Rental companies set their own higher thresholds, commonly 21 or 23, and some add a young-driver surcharge up to age 25.
Every registered vehicle must carry Por Ror Bor, which covers third-party injury only. Rental companies typically layer on additional collision and theft coverage. Check what is included and what excess (deductible) you remain liable for.
Most rental companies require a credit card in the driver's name for a pre-authorised security deposit. Amounts and acceptable card types vary by company. Debit cards or cash deposits are rarely accepted.
Thailand drives on the left. Speed limits are 60 km/h in built-up areas and 90, 120 km/h on expressways unless signed otherwise. U-turns are common and legal at designated breaks. Motorcycles often pass on both sides, so shoulder-check before changing lanes.
Helpful Tips
Pick up at BKK airport for the widest vehicle choice and 24-hour desks. But expect a 30-45 min queue; city-center offices in Sukhumvit or Silom can be faster and often waive one-way drop fees within Bangkok.
Shoot a 360° video of every panel, alloy wheel, and the odometer before leaving the lot; Thai fleets range from near-new to well-worn, and many operators note even tiny scratches on return.
Google Maps works reliably nationwide, including real-time traffic in Bangkok and turn-by-turn in English. For offline backup, download the map for each province in advance or use the Thai app Longdo Maps.
Most rentals use petrol (91 or 95) on a full-to-full policy, fill up at PTT or Bangchak stations on main roads before return, as airport pumps charge a premium and prepaid fuel is rarely offered.
Expect guarded hotel or mall parking (20, 60 THB/hr) in central Bangkok and Chiang Mai's Old City. Overnight street parking is common in smaller towns but always remove valuables and fold in mirrors.
Driving Warnings
At red lights, turning right is only allowed when a green arrow is displayed. Doing it on a plain red is illegal and carries an on-the-spot fine.
During April, May, sudden monsoon downpours flood stretches of Sukhumvit Road between Soi 22 and Asoke, creating deep standing water that can stall cars.
From 07:00, 09:00 and 17:00, 19:00, the intersection of Rama IV and Silom becomes gridlocked. Police actively ticket drivers who block the box.
Speed cameras are common on the Bangkok, Chonburi Motorway (Highway 7) and fines start at 500 baht for exceeding 120 km/h; rental cars receive tickets by mail weeks later.
