Riding a Scooter in Chiang Mai: Traffic, Rules and Tips from a Local Rental (2026)

Chiang Mai is one of the easiest cities in Thailand to explore by scooter, and it still has its own rules of the road. Traffic drives on the left, scooters are everywhere, and the police check helmets and licenses at regular checkpoints. Outside the city, the mountain roads that make the region famous need a different kind of riding. This guide is what we tell our own customers before their first ride: practical, local and honest.

• Traffic: keep left
• Helmet: always, both riders
• Fine without helmet: up to 2,000 THB
• Emergency: 1669 · Tourist police 1155

How traffic works in Chiang Mai

• Keep left. Thailand drives on the left. Ride on the left side of your lane and let faster traffic pass on the right.
• Scooters filter forward at red lights and gather at the front. Do it slowly and only when there is room; never squeeze between moving cars.
• U-turns are how you change direction on big roads: there are special U-turn lanes on the right. Move over early and watch for oncoming traffic.
• Turning left on a red light is allowed only where a sign says so. Otherwise, wait for green.
• Expect the unexpected: cars pulling out without looking, scooters riding against the traffic close to the curb, dogs crossing. Ride with a margin and cover the brakes in busy streets.
• Use your mirrors and indicators before every lane change, and remember to switch the indicator off.

The Old City and the moat

The square Old City is surrounded by a moat with a road on each side. The moat roads are one-way, with traffic running in opposite directions on the inner and outer sides: follow the arrows and plan your turns before you reach the corners. Inside the walls, the lanes are narrow and slow, full of pedestrians and temples: ride at walking speed. On Sunday evenings parts of the Old City close for the Walking Street market; park outside and walk in.

Helmets, licenses and police checkpoints

Checkpoints are common in Chiang Mai, especially around the Old City moat, in Nimman and on the roads out of town. Officers usually check three things: helmet, license and the bike’s documents. Riding without a helmet can cost up to 2,000 THB, and if your passenger has none, the rider can be fined double. Riding without a valid license usually means a fine of 500–1,000 THB, and you may not be allowed to ride on.

For a tourist, a valid license means a motorcycle license from home plus an International Driving Permit with the motorcycle category, or a Thai motorcycle license. A car license is not enough, and your travel insurance will most likely not pay after an accident without the right license. Everything in detail: Do you need a license to ride a scooter in Thailand?

Parking

• Park where other scooters are parked, in a neat row, front wheel to the curb.
• Don’t park on red-and-white curbs, in front of gates and driveways, or on the parade route during festivals: police lock or move bikes left there.
• Many malls, markets and temples have scooter parking, sometimes for a small fee.
• Lock the steering, take your helmets with you or lock them to the bike, and take a photo of where you parked.

Fuel

Petrol stations are everywhere in the city and on the main roads; most have an attendant who fills the tank for you. Ask for "Gasohol 95, full". On mountain routes, fill up before you leave the main road: on long climbs there can be many kilometers without a station. All our bikes are handed over with a full tank and go back with the same level.

Riding outside the city: mountain roads

The best rides around Chiang Mai go into the mountains: Doi Suthep, the Samoeng Loop, Doi Inthanon, Mae Kampong, the road to Pai. They are paved and beautiful, and they need a different technique from city riding:

• Slow down before the bend, not in it, and stay in your lane: pickups and minivans sometimes cut corners.
• On long descents, use both brakes smoothly and progressively and don’t drag them all the way down: they overheat. On a manual motorcycle, use a low gear.
• Sand and leaves collect on the inside of tight bends, especially in the dry season.
• Daylight only: the hills get dark quickly and there are no streetlights.
• Scooters stay on paved roads. Dirt tracks are for the Kawasaki KLX 150.

Our route guides tell you how hard each road is: Doi Suthep, Samoeng Loop, Doi Inthanon, Mae Kampong, Chiang Dao, Sticky Waterfall, Pai.

Seasons: rain and smoke

• Cool season (November–February): the best riding of the year. Mornings in the mountains can be cold: bring a jacket.
• Hot and smoky season (March–April): seasonal burning often brings smoke and haze. Check the air quality, wear a mask, and keep long rides for clearer days.
• Rainy season (June–October): short, heavy showers. Roads get slippery, especially painted lines and metal covers. When it pours, stop under a roof and wait: it usually passes within the hour. A raincoat is free on request with our rentals.

If something goes wrong

If there is an accident, take care of people first: move to safety and call 1669 for an ambulance if anyone is hurt. The police number is 191, the English-speaking tourist police 1155. Then call or message us. If the bike breaks down, message us before you do anything else: we help with the communication with a local repair shop.

Your rental includes Thailand’s compulsory insurance (Por Ror Bor), which covers injuries up to the legal limits but not damage to the bike. Check that your travel insurance covers motorbike riding, the engine size and a passenger. Details are in our rental terms.

Which bike for a first ride

If you are not confident in traffic yet, tell us: we suggest a smaller, lighter scooter and quiet roads to start on. All rentals come with two helmets and a phone holder. See all prices and our complete rental guide.
