ECE vs. TISI vs. DOT: Motorcycle Helmet Standards Explained in Thailand
When you’re buying a motorcycle helmet in Thailand, you’re met with a alphabet soup of certifications: ECE, TISI, DOT. What do they all mean? Which one is required, and which one offers the best protection? Choosing the right standard isn't about bureaucracy—it’s about understanding the level of protection you’re putting on your head.
This guide cuts through the confusion and explains the key differences between the major helmet safety standards you'll encounter, so you can make an informed decision that could save your life.
Why Certification Matters: More Than Just a Sticker
A safety standard is not a suggestion; it’s a set of rigorous laboratory tests that a helmet must pass to be certified. These tests simulate impacts, check strap strength, and assess whether the helmet will stay on your head in a crash. A certified helmet has been objectively proven to meet a baseline level of protection. An uncertified helmet is a gamble with your life.
The Gold Standard: ECE 22.06
What it is: The Economic Commission for Europe (ECE) regulation is a globally recognized and continuously updated safety standard, currently at version 22.06. It is considered the international gold standard for helmet safety.
Where it's required: It is mandatory for all motorcycle helmets sold in over 50 countries, including most of Europe.
Key Testing Features:
Rigorous Impact Testing: Tests are conducted on a wider range of impact zones on the helmet.
Advanced Roll-Off Test: A sophisticated test to ensure the helmet stays on during an accident.
Strap Strength Test: The chin strap must be extremely strong to prevent the helmet from coming off.
Peripheral Vision Check: Ensures the helmet does not block your view.
Who should use it: Anyone who wants the highest available level of proven protection. For riders in Thailand, an ECE-certified helmet represents the top tier of safety.
The Thai Standard: TISI Mark
What it is: The Thai Industrial Standard Institute (TISI) mark is the official mandatory certification for helmets sold in Thailand. It is illegal to sell a new motorcycle helmet in Thailand that does not carry the TISI mark.
Where it's required: Mandatory by law in Thailand.
Key Testing Features: The TISI standard ensures a helmet meets minimum safety requirements for:
Impact Absorption: The helmet's ability to absorb energy upon impact.
Strap Effectiveness: Ensures the retention system is strong enough to hold the helmet securely in a crash.
Basic Construction Quality.
Who should use it: Every rider in Thailand must use a TISI-certified helmet to comply with the law. It provides a vital, government-approved base level of protection and is a significant step up from an uncertified helmet.
The American Standard: DOT FMVSS 218
What it is: The Department of Transportation (DOT) standard, Federal Motor Vehicle Safety Standard (FMVSS) 218, is the minimum legal requirement for helmets in the United States.
Key Consideration – The Self-Certification Problem: Unlike ECE or TISI, where an independent body tests the helmets, the DOT standard operates on self-certification. This means the manufacturer itself certifies that its own helmets meet the standard. This system has led to widespread issues with counterfeit helmets that bear fake DOT stickers but offer little to no protection.
Who should use it: If you are purchasing a helmet from a renowned, trustworthy international brand, a real DOT certification can indicate safety. However, buyers must be extremely vigilant against counterfeits. A DOT-only helmet does not satisfy the legal requirement in Thailand unless it also carries the TISI mark.

The Verdict: Which Standard Should You Choose in Thailand?
Your priority must always be a helmet that is legally compliant and safe.
The Legal Requirement & Smart Choice: Every helmet you buy must have the TISI mark. This is the non-negotiable starting point for safety and legality in Thailand.
For Maximum Safety (Highly Recommended): Look for a helmet that has both the TISI mark and an ECE 22.06 certification. This combination ensures you meet the Thai legal requirement while also benefiting from the highest international standard of protection available.
Use Extreme Caution: Be wary of helmets that only have a DOT sticker. They may be counterfeits and they do not satisfy Thai law unless they also have the TISI mark.
Remember, the certification is just the first step. A helmet must fit perfectly to work correctly. For a complete guide on how to choose and fit your helmet, read our definitive resource: The Ultimate Guide to Motorcycle Helmet Safety in Thailand.
