What driving in Thailand is like
The Mae Hong Son Loop from Chiang Mai (Route 1095, ~600 km with 1,864 curves) is the country's most celebrated mountain drive. For most visitors the real draw is the freedom to reach places trains and tours don't, on your own schedule, with the open road generally capped around 120 km/h on designated motorways. Getting behind the wheel is the easy part: your International Driving Permit is a certified translation of your Singapore licence, carried alongside it, so rental staff and officials in Thailand can read your credentials at a glance.

Local driving facts in Thailand
Emergency number: 191 (police), 1669 (ambulance) (112 also connects from most mobiles). Typical maximum for cars on the fastest road class: 120 km/h on designated motorways. Posted limits always take precedence.
- Tolls & road charges
- Bangkok and inter-city expressways (EXAT/DOH) charge fixed-amount tolls payable in cash at booths or electronically via the M-Pass or Easy-Pass transponder/sticker; most short urban expressway segments cost roughly 25-90 THB. Unpaid e-tolls now carry escalating penalties, so use cash lanes if your rental has no tag.
- Parking
- Park only in marked bays; illegal or red-and-white-curb parking draws 200-500 THB fines and towing, common in central Bangkok. Malls and BTS-area lots offer paid garages (often 20-40 THB/hr), and apps/attended lots are the safe option in dense districts.
- Penalties & enforcement
- Speeding typically 1,000-2,000 THB, no-seatbelt and mobile-phone use up to 1,000 THB, and drink-driving over 0.05% BAC is heavily fined or jailed; minor fines are frequently issued on-the-spot in cash at checkpoints. Rental firms pass camera/toll tickets to your card plus an admin fee.
- If you have an accident
- Call 1669 for medical emergency and 191 for police (insurance/tourist accident hotline 1554); for any injury or insurance claim a police report is required. Do not move the vehicles until police or the insurer's assessor arrives unless they are blocking a fast lane and you mark positions.
- City driving
- In Bangkok the elevated Chalerm Maha Nakhon / Si Rat expressways bypass notorious surface gridlock but have abrupt left-exit ramps and tight toll plazas; sois (side lanes) are often one-way and flood-prone in the rainy season.
- Winter driving
- No winter-tyre rules - tropical climate.
- Fuel
- Stations (PTT, Bangchak, Shell, Esso) are attendant-served; choose Gasohol 91/95 or E20 for petrol cars and 'Diesel' (B7) for diesels. Cards are widely accepted at branded stations; petrol runs roughly 35-42 THB per litre.
