DOT FMVSS 218 helmet label explained

What FMVSS 218 is

FMVSS 218 is a federal safety standard issued by the National Highway Traffic Safety Administration (NHTSA), part of the US Department of Transportation. That is why people call it the DOT standard. It sets minimum performance requirements for helmets intended for motorcycle riders on public roads, and it applies to every helmet sold for that purpose in the US.

The standard covers three main areas. Impact attenuation measures how much of a blow the helmet absorbs before it reaches the head form. Penetration resistance checks that a pointed striker cannot push through the shell. Retention checks that the chin strap and its fasteners hold under load without stretching too far. The standard also sets a minimum field of view and labeling rules.

Self-certification: why 'DOT approved' is not quite right

DOT does not approve helmets before they go on sale. Under federal law, the manufacturer certifies that its helmet meets FMVSS 218 and applies the label itself. NHTSA then enforces the standard by purchasing helmets on the open market and sending them to test labs for compliance testing.

If a model fails, NHTSA can require the maker to recall it and can seek civil penalties. NHTSA publishes compliance test results, so a helmet model that failed is a matter of public record. This system is different from ECE 22.06, which requires approval by an accredited lab before sale plus batch testing of production. For the full comparison, see DOT vs ECE vs Snell and our explainer on ECE 22.06.

What a genuine DOT label looks like

Since NHTSA updated its labeling rule in 2013, a compliant helmet carries a label on the outside back of the shell with several required elements, not just the three letters DOT. The label must be permanently attached and legible. Some makers put it under a clear coat; others use a sticker.

Inside the helmet, there should also be a permanent label with the manufacturer's name, the size, the month and year of manufacture, and information about the materials and care. Missing interior labeling is a warning sign.

• The text FMVSS No. 218
• The word CERTIFIED
• The manufacturer's name or brand
• The model designation

How to spot a novelty helmet with a fake sticker

Novelty helmets are thin shells sold for looks. They are not built to pass FMVSS 218, and some are sold with a loose DOT sticker in the box or with a fake one already applied. NHTSA has published guidance on identifying them, and the physical signs are usually obvious once you know what to look for.

Note.A novelty helmet offers little or no impact protection. Do not ride in one, even if it has a DOT sticker. If a helmet seems suspiciously light or cheap, check the maker and model against NHTSA's records.

DOT alongside ECE and Snell labels

Many helmets sold in the US carry more than one rating. A helmet can be DOT certified and also carry an ECE 22.06 approval label, usually sewn onto the chin strap, and a Snell sticker inside. Each label means the model met that standard's test at the time it was made. None of them promises a particular outcome in a crash.

For US street riding, the DOT label is the legal requirement. ECE 22.06 adds tests DOT does not have, including an oblique impact test for rotational forces. Snell M2020 is a voluntary standard run by the private Snell Memorial Foundation, with M2020D aimed at DOT markets.

Buying safely: checks before you pay

Buy from an authorized dealer or the brand's official store where you can. Counterfeit premium helmets exist, and they copy the label along with the graphics. A price far below what every other retailer charges is a reason to be cautious.

Avoid used helmets unless you know their full history. A helmet that has been dropped or crashed can have crushed EPS that you cannot see. See when to replace a motorcycle helmet and what to do with a helmet after a crash.

1. 1

   Find the label on the outside back of the shell and check it has every required element.

2. 2

   Look inside for the permanent label with size and date of manufacture.

3. 3

   Press on the liner. You should feel firm EPS foam under the comfort padding.

4. 4

   Check the weight feels substantial, around 3 pounds or more for a full face helmet.

5. 5

   Make sure the maker and model are real and sold by known retailers.

Frequently asked questions

Is DOT approved the same as DOT certified? In everyday use, yes, but certified is the accurate term. The maker certifies compliance and NHTSA tests helmets after they are on sale.

Can I buy a DOT sticker and put it on my helmet? Putting a DOT label on a helmet that has not been certified does not make it compliant. The protection comes from the helmet's construction, not the sticker.

Do all US states require a DOT helmet? Helmet laws vary by state. Where a helmet is required for street riding, it must meet FMVSS 218. Check your state's current rules.

Is an ECE-only helmet legal in the US? A helmet sold for US on-road use is required to meet FMVSS 218. Many ECE helmets sold in the US also carry DOT certification, so check for both labels.
