Quick answer
Thailand drives on the left. Chiang Mai traffic operates on mutual adjustment rather than strict lane discipline. The key skill is reading the flow, not just following the rules.
How does Chiang Mai traffic actually work?
It is denser and less formally structured than most visitors expect. Vehicles of all sizes share road space without strict lane discipline. Scooters filter between lanes, and at intersections, the flow operates more on mutual adjustment than strict right-of-way rules. The key habit is to stay aware of vehicles on all sides and not assume that a green light means the intersection is clear.
Do I need to drive on the left or right in Thailand?
Thailand drives on the left — the same as the UK, Japan, Australia, and most of Southeast Asia. If you are from a right-hand-drive country, this affects your spatial awareness more than anything else. The main risk is misjudging distances and clearance when overtaking or passing oncoming traffic.
Are there bike lanes or designated scooter routes in Chiang Mai?
There are no dedicated scooter lanes in the way some Asian cities have them. In practice, scooters ride wherever vehicles ride, and occasionally on the pavement when traffic is heavy. There are some wider sois with informal scooting lanes, but these are not marked or enforced consistently. Plan for mixed traffic, not segregated lanes.
What are the most common traffic rules in Chiang Mai?
Give way at roundabouts is the most important to understand — vehicles already in the roundabout have priority. Indicators are often treated as optional. Speed limits in the city are low and enforced near schools and hospitals. Horn use is a warning signal, not an expression of frustration. Police checkpoints are common on major roads out of the city.
Can I use Google Maps or another navigation app while riding in Chiang Mai?
Yes, but with a mount and a hands-free setup. Trying to hold a phone while riding in Chiang Mai traffic is genuinely unsafe. Download offline maps for the Chiang Mai region before you go — mobile signal is patchy on mountain roads. Maps.me and Waze are also commonly used. Google Maps generally handles Chiang Mai well for city routes.
What are the speed limits in Thailand and how are they enforced?
Inside city limits, the limit is typically 60km/h. On two-lane highways outside the city, 90km/h is common. On divided highways, 100–120km/h depending on the road. Speed enforcement uses both police checkpoints and camera systems. On popular mountain routes like the Samoeng Loop, police checkpoints appear periodically, particularly on weekends.
