As part of an ongoing initiative to improve road safety across Thailand, traffic laws and penalties have become significantly stricter.
Fines for common violations have increased sharply to encourage safer driving habits and better compliance.
For instance, driving or riding a motorcycle without a valid license now carries a 1,000 THB fine, doubling the previous 500 THB penalty. Similarly, the fine for riding without a helmet has quadrupled from 500 THB to 2,000 THB.
A complete breakdown of these updated penalties can be found in the comparison table below.
Thailand has seen a steady rise in road accidents over the past decade, with motorcycles involved in the majority of incidents. In response, the Thai government launched a comprehensive road safety initiative aimed at reducing accidents and improving driver behaviour across the country.
The updated penalties, introduced in recent years, are designed to act as a stronger deterrent. By significantly increasing fines, authorities hope to encourage riders and drivers to think twice before breaking the rules. The message is clear: road safety is a priority, and non-compliance will come at a cost.
Key reasons behind the fine increases:
Rising accident rates – Thailand consistently ranks among the countries with high road fatality rates, and motorcycles are a major factor.
Tourist behaviour – Many visitors are unfamiliar with Thai traffic rules or ride without proper licences, leading to accidents.
Enforcement improvement – Police checkpoints are more frequent, especially in tourist areas like Chiang Mai, Phuket, and Pattaya.
Public demand – There is growing public support for stricter enforcement to make roads safer for everyone.
The result is a tougher approach to traffic violations that affects both locals and tourists alike. Understanding these changes can help you avoid fines and stay safe on the road.
Riding without a helmet.
Always wear a helmet when riding a scooter in Chiang Mai. Traffic can be unpredictable, and accidents happen more often than many visitors expect. A helmet could save your life. The penalties have also increased significantly. If you are stopped by the police without a helmet, the fine is now 2,000 THB per person. If both the rider and passenger are not wearing helmets, the total fine can be 4,000 THB.
Riding without a license.
Many tourists ride scooters without a valid Thai motorcycle licence or an International Driving Permit (IDP) with motorcycle entitlement. While this is common, it is still illegal. If you are caught riding without the correct licence, the current fine is 1,000 THB.
Speeding
Speeding fines have increased from 1,000 THB to 4,000 THB. The safest approach is to follow local traffic flow, stay in the left lane, and ride at a comfortable pace. Chiang Mai is best enjoyed slowly anyway.
Reckless Riding
Dangerous or irresponsible riding can result in severe penalties. Offences such as riding on the wrong side of the road, using pedestrian walkways, street racing, or other reckless behaviour can lead to fines of up to 20,000 THB, and in some cases, imprisonment.
Jumping a Red Light
Pay close attention at intersections and traffic lights. If the light is changing, it is always safer to stop and wait. Running a red light can result in a 4,000 THB fine.
Drunk driving/riding
Thai authorities are actively cracking down on drink driving. If you are caught riding or driving under the influence of alcohol, you can expect substantial penalties, including fines of 20,000 THB or more and possible jail time.
Getting fined can ruin your day and put a dent in your travel budget. The good news is that most fines are completely avoidable with a little preparation and common sense. Here are our top tips for staying on the right side of the law in Chiang Mai.
1. Always wear a helmet
This might seem obvious, but many tourists ride without a helmet – especially on short trips or in hot weather. Thai law requires both the rider and passenger to wear helmets at all times. With fines now at 2,000 THB per person, it's an expensive mistake to make. More importantly, a helmet could save your life.
There's another reason to wear one: not wearing a helmet makes you a visible target for the police. They will pull you over immediately, and once they stop you, they'll check your licence, passport, and documents. If you're missing any of those, you could end up paying even more fines on top of the helmet penalty. It's a chain reaction that's easily avoided by simply strapping on a helmet before you ride.
2. Carry the right licence
You need either a valid Thai motorcycle licence or an International Driving Permit (IDP) with motorcycle entitlement, along with your home country licence. Without these, you can be fined 1,000 THB.
3. Know the traffic rules
Familiarise yourself with Thai traffic laws before you ride. Remember to:
Drive on the left side of the road
Stop at red lights (no jumping!)
Obey speed limits
Give way to pedestrians at crossings
Never use your phone while riding
4. Avoid drinking and riding
Thailand has a zero-tolerance approach to drink driving. The fines are steep (up to 20,000 THB) and you could face jail time. If you're planning to drink, use a taxi or songthaew instead.
5. Stay aware of police checkpoints
Police checkpoints are not as common in Chiang Mai as they once were. The police have significantly reduced the number of checkpoints they operate in recent years, with some saying the law no longer allows them as freely as before.
That said, you may still come across them:
Near the Old City
On major roads like Huay Kaew Road and Nimmanhaemin Road
Around tourist attractions
During holiday periods and festivals
If stopped, remain calm and polite. Show your documents and accept any fine without argument.

Honda Scoopy 110cc
The Honda Scoopy is incredibly popular with locals, thanks to its light frame, nimble handling, and ease of use. It's the ideal scooter for navigating the narrow sois of Nimmanhaemin and the historic Old Town. The low seat height makes it especially accessible for shorter riders. While it's not built for mountain trips like Doi Suthep (save those for our Click 160cc), it excels at relaxed, stylish urban exploring.
