Get an International Driving Permit before you fly, refuse to leave your passport as deposit, wear a helmet always, avoid the Super Highway and the Doi Suthep road on busy weekends, and confirm in writing what your travel insurance covers for two-wheeled vehicles. Standard rental: ฿200–฿300 a day for a 125cc, ฿2,000–฿5,000 cash deposit. Everything below is the practical playbook, including which shops we send guests to and the three streets we tell them to avoid.
Do I really need an International Driving Permit in Chiang Mai?
Yes, legally. Thai police checkpoints around Chiang Mai issue fines for foreign drivers without an IDP, and your travel insurance will deny any accident claim if you didn't have one.
Thailand's Land Traffic Act requires foreign drivers to hold either a Thai licence or an International Driving Permit (IDP) under the 1949 Geneva Convention. The IDP is a translation of your home licence — you carry both together. Issuance takes 5–15 minutes at most automobile associations (AAA in the US, the IAM in the UK, RACQ in Australia) and costs $20–$30.
Many rental shops will rent without checking, especially the smaller ones in the Old City. The risk isn't the shop — it's the checkpoints. Chiang Mai police run intermittent stops on the main roads around the Old City and on the way up to Doi Suthep. Foreign-tourist scooter rentals are a known revenue stream for on-the-spot fines (฿500–฿1,000 cash). Worse, if you crash without an IDP, the insurer has a clean exclusion to refuse the hospital bill.
Should I ever leave my passport as a deposit?
No. Always pick the cash-deposit option, even if it's ฿1,000 more. Without your passport you cannot fly home, change hotels, or prove identity at a hospital.
The standard Chiang Mai rental shop offers two deposit options: your passport, or ฿2,000–฿5,000 cash. The passport option is convenient if you forgot to bring cash, and unscrupulous shops know it.
The risk plays out like this: you return the scooter, the shop "finds" a scratch you swear wasn't there at pickup, and demands ฿4,000–฿15,000 for repair. Without your passport, you cannot leave. You either pay and lose the money, or argue for hours and miss your flight. We've heard a version of this story roughly once a month for the past three years.
What does travel insurance actually cover for scooters?
Most standard policies exclude scooters entirely or require a licence-in-country-of-travel clause. Bought-in-Thailand coverage is patchy. Read the fine print before you ride.
A short tour of the policies we see most often:
- World Nomads. Covers up to 125cc with both a home-country motorbike licence and an IDP. Anything over 125cc requires the "Adventure" add-on.
- SafetyWing. Covers up to 250cc with a valid licence. No IDP requirement in some policies — check yours.
- Allianz / AXA / standard travel policies. Typically exclude two-wheeled motor vehicles entirely without a specific rider.
- Credit-card-included travel insurance (Chase Sapphire, Amex Platinum). Almost always excludes motorbikes.
- Thai operator insurance (sold at the rental shop). Cheap (฿100–฿200/day) and usually only covers third-party liability — not your own hospital bill.
For comparison, the U.S. Consular Information Sheet on Thailand road safety (accessed 2026-02-10) specifically flags that motorbike accidents are the leading cause of US-citizen deaths in Thailand and that US citizens "should not assume their US health or auto insurance applies".
Which streets in Chiang Mai should I avoid?
The Super Highway (Route 11), the Doi Suthep climb on weekends, and the Old City moat clockwise loop during evening rush. Plus the main Mae Rim Road on weekends.
| Road | Why avoid | Safer alternative |
|---|---|---|
| Route 11 (Super Highway ring) | Truck-heavy, multi-lane, fast — tourists hit here yearly | Use the inner ring road (Manee Nopparat / Wuallai) |
| Doi Suthep road on Sat/Sun | Tour buses + steep hairpins + impatient minivans = head-on risk | Go early (06:30–08:30) or take a songthaew up |
| Old City moat (clockwise outer) | One-way confusion, U-turning cars without signal | Use side sois inside the moat for short hops |
| Mae Rim Road on weekends | Heavy tour-van traffic to elephant camps + Queen Sirikit Botanic | Weekdays only, or use a hired van |
| Loi Kroh Road at night | Narrow + busy + bar traffic + drunk drivers | Park, walk this stretch |
| Nimman Soi 7 / Soi 9 evening | Cafe overflow + delivery scooters + foot traffic — slow but messy | Fine to ride, just expect to creep |
What's the right bike for my trip?
For Old City + temples + a Doi Suthep run: 125cc automatic. For Mae Hong Son loop or longer mountain riding: 150cc+. For solo riders short on confidence: don't rent — hire a driver.
If the Doi Suthep climb is the only mountain ride you wanted and the weekend traffic puts you off, a guided Doi Suthep temple and Hmong village tour covers the same road without you having to fight the hairpins and minivans.
The Honda Click 125 and Yamaha Mio are the workhorses. ฿200–฿300/day, easy to handle, comfortable for 50–80km/day of city + suburban riding. If you've ridden a scooter before, you'll be comfortable on these in 15 minutes.
The PCX 150 / NMAX 155 are step-up bikes — same controls, more torque, better for two-up riding and longer distances. ฿350–฿500/day.
The CB150X / XSR155 / CRF250 are proper motorbikes for the Mae Hong Son loop, the Samoeng loop, or anyone who already rides at home. ฿700–฿1,500/day. Don't book one as your first-ever experience.
If you've never ridden a scooter, our honest advice is: don't learn in Chiang Mai. Hire a driver for ฿1,200–฿1,800 for a half-day, or use Grab. The cost difference over a week is ฿3,000–฿5,000 vs the risk of a ฿100,000 hospital bill. If you still want the two-wheeled feel without the traffic risk, a guided scooter adventure and river cruise puts a local rider in front, or you can stay car-free entirely on a Chiang Mai cycling tour.
How does the deposit-and-handover process actually work?
Take photos of every panel, scratch and dent before you ride. Note fuel level. Confirm cash deposit, not passport. Get a written receipt.
Step-by-step:
- Compare two shops minimum. Walk the block. The shops 100m apart vary by ฿50–฿100 a day.
- Inspect the bike thoroughly. Tyres (tread depth and pressure), brakes (front and back, test in the shop), lights (front, brake, indicators), horn, fuel gauge.
- Take dated photos. Every panel. The seat. The wheels. Email them to yourself so they're timestamped.
- Confirm the cash-deposit option. ฿2,000–฿5,000 is reasonable. Passport-only is a red flag.
- Get a written receipt or contract showing daily rate, deposit amount, return date, and what insurance (if any) is included.
- Confirm fuel-return policy. Most shops are "return with the level you got it at"; some are "return full".
What about the Mae Hong Son loop specifically?
3–4 day, ~600km, 1,864 curves on the Pai stretch. Rentable on a 150cc+, but most riders end up wishing they had a 250cc. Plan two refuel stops and a backup brake-pad budget.
The Mae Hong Son loop is the country's most famous motorbike route — Chiang Mai → Pai → Mae Hong Son → Mae Sariang → Doi Inthanon → Chiang Mai. Three nights minimum, four nights to do it relaxed. The Pai-to-Mae Hong Son stretch has 1,864 numbered curves carved into the road sign at the climbing start. It's a real ride, not a leisurely roll.
The bike to rent: Honda CB150X, Yamaha XSR155, or Honda CRF250 for the more confident. Mr Mechanic and Tony's Big Bikes rent these at ฿700–฿1,500/day. Take it for a half-day around Chiang Mai before committing.
Our Mae Hong Son loop guide covers the full route, where to stay each night, and which sections have unreliable fuel.
Where should I park, and what about petrol?
Park inside hotel grounds whenever possible. For petrol, 91-octane (green pump) is the right choice for almost every rental.
Hotel parking is usually free for guests and removes the theft and damage risk. Street parking inside the Old City is generally safe in daylight, less so overnight — chain the bike if you can. Nimman has a few paid lots (฿20–฿40 per evening) that are worth it for peace of mind.
Petrol: Thai 91 is regular unleaded; Thai 95 is premium. Almost every rental scooter takes 91. PT, Bangchak and Shell stations are everywhere — full-service, attendant fills the tank. Cash works; some take card. ฿100 of fuel covers roughly 150km on a 125cc, 100km on a 150cc.

Frequently asked questions
Is an International Driving Permit required to rent a scooter in Chiang Mai?
Legally, yes. Thailand's Land Traffic Act requires foreign drivers to hold either a Thai licence or an International Driving Permit (IDP) issued under the 1949 Geneva Convention, paired with their home licence. In practice, many rental shops will hand you keys without checking. The risk is not at the rental shop — it's at the police checkpoint. Driving without an IDP voids your travel insurance, opens you to a ฿500–฿1,000 on-the-spot fine, and gives the insurer a clean reason to deny any hospital claim if you crash. Get the IDP before you fly.
Is leaving your passport as a deposit safe?
Common but risky. The standard Chiang Mai rental deposit is your passport OR ฿2,000–฿5,000 cash. Reputable shops accept the cash option. Avoid any shop that insists on the passport — without your passport you cannot check out of a hotel, fly home, or prove identity at a hospital. If your scooter is damaged and you've left the passport, the shop has leverage to inflate the repair quote knowing you can't leave the country until you pay. We tell every visitor: cash deposit only, even if it's ฿1,000 more expensive. Reputable shops include POP Big Bike, Mr Mechanic, and Joy Scooter Rental.
Does my travel insurance actually cover scooter accidents?
Usually not unless you bought a specific motorbike rider. Standard travel insurance from World Nomads, SafetyWing or Allianz excludes 'two-wheeled motor vehicles over 125cc' or excludes them entirely without a licence in the country of travel. World Nomads covers up to 125cc with proof of a valid licence in your home country plus an IDP. SafetyWing covers under 250cc with a valid licence. Read the exclusions before you ride. The hospital bill for a Chiang Mai scooter accident with a broken collarbone runs $3,000–$8,000 at Chiang Mai Ram or Bangkok Hospital. Uninsured, that's a holiday-ending bill.
Which Chiang Mai streets should I avoid on a scooter?
Three categories. One — the Super Highway (Route 11) around Chiang Mai. Truck traffic, multi-lane, foreign tourists die on it most years. Two — the road up to Doi Suthep at peak weekend hours. Steep, twisting, slow tour buses + impatient minivans. Three — the Old City moat road during evening rush. The clockwise one-way system catches every first-timer; cars cut across to U-turns without signalling. Stick to the secondary roads (Sripoom, Manee Nopparat, the Nimman grid sois) until you've ridden for a day or two.
What's the daily rental rate and what's included?
Daily rates for a basic 110–125cc automatic (Honda Click, Yamaha Mio) run ฿200–฿300. A 150cc semi-auto (PCX) is ฿350–฿500. A larger 250–400cc cruiser or adventure bike is ฿800–฿1,500. Helmets are usually included (always wear one — it's the law and the difference between bruises and brain trauma). Insurance is rarely included; ask explicitly. Most shops require you to refill the tank before return — ฿100 of fuel covers roughly 150km on a 125cc. Weekly rentals are typically priced as 6 days × daily rate.
Can I rent a scooter for the Mae Hong Son loop?
Yes, but only on a 150cc+ bike with confidence riding mountain switchbacks. The Mae Hong Son loop is roughly 600km over 3–4 days, with 1,864 documented curves on the Pai-to-Mae Hong Son stretch alone. A 125cc Click will do it but you'll be passed by trucks on every uphill. The bike to rent for the loop is a Honda CB150X, Yamaha XSR155, or Honda CRF250. Shops like Mr Mechanic and Tony's Big Bikes rent at ฿700–฿1,500/day. Take it for a half-day in town first to make sure you're comfortable before committing to the loop.
