When was it law to wear a crash helmet? That question sounds simple, but the answer depends on the country. Motorcycle helmet laws did not start everywhere at the same time, and the rules changed a lot over the years.
When I looked into the history, one thing stood out. In the United States, helmet laws began appearing in the 1960s, while in the United Kingdom, wearing a crash helmet became compulsory in 1973. Here is how those changes happened and why they still matter today.
When was it law to wear a crash helmet in the United States?
In the U.S., motorcycle helmet laws started appearing in the mid-1960s. The National Highway Traffic Safety Administration says the first universal helmet law was enacted in 1966. State laws then spread quickly after federal highway safety standards were issued.
This is one part of the history that can be confusing. People often talk about “the first helmet law” as if the whole country adopted one law on one date. That did not happen.
The first U.S. helmet laws appeared in the 1960s
By 1967, many states had laws requiring motorcycle riders to wear helmets. NHTSA records that 22 states adopted helmet-use laws in 1967, with another 14 states adding such laws in 1968.
| Year | What happened |
|---|---|
| 1966 | First universal motorcycle helmet law was enacted |
| 1967 | 22 states adopted helmet laws |
| 1968 | 14 more states added helmet laws |
| 1975 | Nearly all states had universal laws |
The rapid spread was not just a state-by-state safety campaign. Federal highway policy also played a major role.
Why did helmet laws spread so quickly?
The federal government tied highway funding incentives to motorcycle helmet laws. That gave states a strong reason to adopt universal rules.
By 1975, almost every state and the District of Columbia had a universal motorcycle helmet law. NHTSA notes that universal laws were in effect in 47 states and D.C. at that point.
That was a very different legal landscape from today.
When did the United States start changing its helmet laws?
The big change came in 1975 and 1976. Congress removed the federal penalties tied to states having universal motorcycle helmet laws.
Once that pressure disappeared, many states changed their laws. Some repealed helmet laws completely. Others kept them but limited them to younger riders.
NHTSA’s historical research shows that by 1978, 25 states had repealed their universal laws or changed them to cover only certain ages.
| Period | General trend |
|---|---|
| 1966–1975 | Universal laws spread quickly |
| 1976–1980 | Many states weakened or repealed them |
| 1980s | Laws were more stable |
| 1990s onward | Some states restored universal laws |
This history explains something that often surprises people today: U.S. helmet laws are not simply the result of one national rule.
When was it law to wear a crash helmet in the UK?
If you mean the phrase “crash helmet” in the British sense, the answer is much more specific.
In the UK, motorcycle and moped riders were legally required to wear safety helmets starting in 1973. GOV.UK’s history of road safety states that safety helmets became compulsory for moped and motorcycle riders that year.
The legal requirement took effect on 1 June 1973. HM Revenue & Customs also records that the regulation made helmet use compulsory and required approved helmet designs.
What changed in 1973?
Before the law, riders could choose whether to wear a helmet. There had already been public safety campaigns encouraging helmet use, but wearing one was not yet a general legal requirement.
The 1973 rule changed that.
| UK date | Helmet-law development |
|---|---|
| Before 1973 | Helmet use was encouraged but not generally compulsory |
| 1 June 1973 | Motorcycle helmet use became compulsory |
| 1976 | Sikh turban exemption became law |
| Today | Approved helmets remain required on UK roads |
The UK government still requires riders to wear an approved helmet when riding a motorcycle or moped on the road.
Why did governments make crash helmets compulsory?
The main reason was simple: motorcycles give riders very little protection in a crash.
A rider does not have a metal body around them like someone in a car. If a crash happens, the rider can hit the road, another vehicle, or another object.
Helmet laws were therefore introduced as a road-safety measure.
When I looked at the research behind these laws, the numbers were hard to ignore. NHTSA says motorcycle helmets can reduce rider fatalities by about 22% to 42% and reduce brain injuries by about 41% to 69%.
| Helmet benefit | Research finding |
|---|---|
| Lower death risk | About 22%–42% reduction |
| Lower brain injury risk | About 41%–69% reduction |
| Helmet use | Much higher where universal laws apply |
The legal debate has never been only about whether helmets work. It has also involved personal choice, enforcement, government power, and the cost of motorcycle crashes.
Did every U.S. state keep its helmet law?
No. This is one of the most important lessons from the history.
Many states weakened or repealed universal laws after federal incentives changed. Some later brought universal laws back.
For example, Texas had a universal helmet law from 1968 to 1977. The law was later weakened and eventually restored to universal coverage in 1989. The Insurance Institute for Highway Safety notes that the changes were followed by major differences in motorcycle crash outcomes.
Why does this history still matter?
It explains why two riders in different states can face very different legal rules.
As of 2026, the U.S. has:
- 17 states plus Washington, D.C. with universal helmet laws
- 30 states with laws covering only some riders
- 3 states with no motorcycle helmet requirement
The three states with no motorcycle helmet law are Illinois, Iowa, and New Hampshire.
| Current U.S. category | Number |
|---|---|
| Universal helmet laws | 17 states + D.C. |
| Partial helmet laws | 30 states |
| No helmet requirement | 3 states |
So, if someone says, “Helmets became law in the 1960s,” that is broadly true for the U.S. history, but it does not mean every state still has the same rule.
What about the phrase “crash helmet”?
“Crash helmet” is an older term for what we now usually call a motorcycle helmet or protective helmet.
The term became especially familiar in the UK and other countries. Modern laws tend to use words such as protective helmet, motorcycle helmet, or safety helmet.
The UK still uses the legal concept of protective headgear. Its Highway Code says motorcycle, scooter, and moped riders and pillion passengers must wear a protective helmet, subject to specific exemptions.
Has the helmet itself changed?
Yes, dramatically.
Older helmets were much simpler than today’s designs. Modern helmets are built around tested safety standards and improved impact protection.
In the U.S., federal regulations require motorcycle helmets sold for road use to meet FMVSS 218 performance requirements.
In the UK, approved helmets can meet standards such as UNECE Regulation 22.05 or 22.06, along with certain accepted British standards.
| Region | Important helmet standard |
|---|---|
| United States | FMVSS 218 |
| United Kingdom | UNECE 22.05 / 22.06 and accepted British standards |
| Main purpose | Tested impact protection |
A common mistake when looking up old helmet laws
One mistake I noticed while researching this topic is treating the law as if it has always been fixed.
It has not.
A state may have required every rider to wear a helmet in 1970, changed the rule in 1977, and then brought universal coverage back years later. That means an old article or newspaper clipping may be correct for its time but wrong for today’s rider.
The same problem happens when people confuse a partial helmet law with having no law at all.
| What you hear | What it may actually mean |
|---|---|
| “No helmet law” | No statewide motorcycle helmet requirement |
| “Adults don’t need helmets” | A partial law may still cover younger riders |
| “Helmet law was repealed” | The law may have been weakened, not fully removed |
That distinction is worth checking before relying on old information.
When did helmet laws become normal?
By the 1970s, helmet laws had become a normal part of motorcycle safety policy in many countries.
The UK made helmet use compulsory in 1973. In the U.S., universal laws spread rapidly during the late 1960s and early 1970s.
The laws then took different paths.
Some countries kept broad requirements. In the U.S., many states changed their laws, while others restored universal rules later.
Today, helmet use is still strongly linked with safer outcomes. IIHS reported that in 2023, observed helmet use was 94% in states with universal helmet laws, compared with 72% in states without universal laws.
What I learned from the history of crash helmet laws
The biggest lesson is that there was never one single worldwide date when wearing a crash helmet suddenly became law.
For the United States, the first universal motorcycle helmet law was enacted in 1966, with many states adopting laws during 1967 and 1968. By 1975, nearly every state had a universal requirement.
For the United Kingdom, motorcycle and moped helmet use became compulsory on 1 June 1973. That is the key date if your question comes from British history or the old term “crash helmet.”
The other lesson is that helmet laws can change. If you are checking whether a rider had to wear a helmet in a particular year, you need the law for that exact place and date rather than relying on today’s rule.
Final Thoughts
When was it law to wear a crash helmet? In the U.S., the story begins in the 1960s, with the first universal law in 1966 and rapid state adoption soon after. In the UK, the clear answer is 1973, when helmet use became compulsory for motorcycle and moped riders.
What surprised me most is how much these laws changed after they were first introduced. Some were repealed, some were weakened, and some came back later. So if you are researching an old accident, newspaper report, motorcycle record, or family story, always check the law that applied at that time.
