Michigan requires a helmet. The exemption is the exception
Start from what the statute actually says, because the popular version of Michigan’s law — “they repealed it, helmets are optional” — skips the part that decides whether you are exempt or in breach.
MCL 257.658 opens with a flat requirement:
“A person operating or riding on a motorcycle shall wear a crash helmet on his or her head.”
Everything else in the section is an exception to that. If you do not fit inside the exception, the general rule applies to you.
The exemption has two conditions, and you need both
For a rider aged 21 or over, the statute requires experience or training, and insurance. Not one or the other. Both.
| Condition | What satisfies it |
|---|---|
| 1. Experience or training | Either you “ha[ve] had a motorcycle endorsement on his or her operator’s or chauffeur’s license for not less than 2 years“, or you have passed a motorcycle safety course |
| 2. Medical coverage | Security for first-party medical benefits payable if you are involved in a motorcycle accident, of not less than $20,000 — and where you carry a passenger, not less than $20,000 per person per occurrence |
Almost every summary of Michigan’s law covers the first condition and treats the second as a footnote. It is not a footnote. Without the $20,000 coverage, the exemption does not apply, and the rider is subject to the general requirement in the first line of the section.
Two practical consequences worth acting on:
- Check your policy before you rely on the exemption. “I have insurance” and “I carry at least $20,000 in first-party medical benefits” are different statements. Ask the question specifically.
- The safety course collapses the two-year wait to zero. A newly endorsed rider who took the course has satisfied condition one immediately; one who passed the tests instead waits two years. That is covered in the Michigan motorcycle safety course, which also waives three separate tests.
Passengers are covered separately
The coverage requirement runs per person. Where an operator carries a passenger, the amount is not less than $20,000 per person per occurrence. Where the passenger is separately insured, that passenger’s own coverage can satisfy their side of it, and the operator still needs the minimum for themselves.
Which means a rider who is properly exempt does not automatically extend that exemption to whoever is on the back. It is checked person by person.
How Michigan compares with the other states we have read
Four states, four different answers, all taken from the statutes themselves. The pattern is more varied than the “helmet state / no-helmet state” shorthand suggests:
| State | Default | Exemption at 21+ | Medical coverage required |
|---|---|---|---|
| Georgia | Helmet required, universally | None that applies to an ordinary rider. O.C.G.A. § 40-6-315 has three narrow exceptions — enclosed cab, motorised cart, agricultural three-wheeler | — |
| Florida | Helmet required | Riders over 21 exempt on the strength of insurance alone | At least $10,000 in medical benefits (FS 316.211) |
| Texas | Helmet required | Riders over 21 exempt with a safety course or medical insurance | The statute fixes no amount. § 661.003 sets no figure — the $10,000 widely quoted for Texas belongs to Florida’s law, not Texas’s |
| Michigan | Helmet required | Riders 21+ exempt with two years’ endorsement or a safety course, and coverage | At least $20,000 (MCL 257.658) |
Three things fall out of that table.
Michigan is the strictest of the three exempting states. Twice Florida’s dollar figure, and it is the only one of the four requiring two conditions to be met simultaneously rather than one.
The Texas row is the one most often reported wrongly, and we corrected it against the statute when we covered the Texas helmet law: § 661.003 states no amount at all. The $10,000 figure repeated across the internet for Texas comes from Florida’s statute.
Georgia shows what a universal law looks like when you read it properly — the Georgia helmet law does have exceptions, but none of them describes a person riding a motorcycle. Florida’s own position is in the Florida helmet law.
Under 21, and the moped line
The exemption is available only from 21. Below that, the helmet requirement in the first line of MCL 257.658 applies without qualification, whatever training the rider has done. The IIHS records Michigan’s law as covering riders “20 and younger”, which is the same rule stated from the other direction.
The IIHS also records a moped exception: a moped, defined by the state as having an engine displacement of 50cc or less and a maximum speed of 30 mph, where the operator is 19 or older.
What the data showed after 13 April 2012
Michigan’s partial repeal took effect on 13 April 2012, and it produced an unusually clean natural experiment — one state, one date, riders either side of it. A peer-reviewed study by researchers at the University of Michigan Injury Center, the University of Michigan Transportation Research Institute and the Insurance Institute for Highway Safety compared the twelve months before with the twelve months after, across 7,235 riders involved in crashes and 1,094 hospitalised at trauma centres.
- Helmet use among riders in crashes fell by roughly a quarter.
- Head injuries rose from 43.4% to 49.6% of riders in the sample.
- Neurosurgical intervention rose from 3.7% to 6.5%.
- Overall fatality rate was essentially unchanged — 3.3% before, 3.2% after.
That last line is worth reading carefully rather than skipping, because it cuts against the simplest version of the argument. Deaths in this dataset did not move; head injuries and neurosurgery did. The finding is about injury severity among survivors, not about mortality.
We are reporting what the study found, and nothing beyond it. This site does not offer legal or medical advice, and does not comment on what any of this means for an individual case.
If you are choosing a helmet anyway
Most Michigan riders wear one whatever the statute allows, and the useful question then is which one. Certifications are less interchangeable than the marketing suggests — what makes a helmet compliant covers what DOT, ECE and SNELL actually test. Fit matters more than any of them, and it is the thing most people get wrong: the helmet size chart and how to measure your head cover the measurement, and how tight a helmet should be covers the check that matters.
The rest of Michigan’s rules
Licensing, including the safety course that waives three tests and satisfies the helmet exemption’s experience condition on the day you pass, is in the Michigan motorcycle license. Michigan also requires a motorcycle to be equipped with adequate seats and foot rests or pegs for each designated seating position, under MCL 257.658a.

Frequently asked questions
Do you have to wear a helmet in Michigan?
The starting point is yes — MCL 257.658 states that a person operating or riding on a motorcycle shall wear a crash helmet. Riders aged 21 and over may be exempt, but only if they meet both of the statute’s conditions.
What are the conditions for Michigan’s helmet exemption?
Two, and both must be met. First, either having held a motorcycle endorsement for not less than two years, or having passed a motorcycle safety course. Second, carrying security for first-party medical benefits of not less than $20,000 — and where a passenger is carried, not less than $20,000 per person per occurrence.
How much insurance do you need to ride without a helmet in Michigan?
At least $20,000 in first-party medical benefits. That is double Florida’s $10,000 requirement, and unlike Florida, Michigan also requires the experience or training condition to be satisfied at the same time.
Can a passenger ride without a helmet in Michigan?
The coverage requirement runs per person, at not less than $20,000 per person per occurrence where a passenger is carried, and a separately insured passenger can satisfy their own side of it. An operator’s exemption does not automatically extend to whoever is on the back.
Does a safety course let you ride without a helmet sooner in Michigan?
It satisfies the experience condition immediately, rather than after two years of holding the endorsement. The $20,000 medical coverage requirement still applies either way.
When did Michigan change its helmet law?
The partial repeal took effect on 13 April 2012. A peer-reviewed study by University of Michigan and IIHS researchers comparing the twelve months either side reported a fall in helmet use among riders in crashes, head injuries rising from 43.4% to 49.6% and neurosurgical intervention from 3.7% to 6.5%, with the overall fatality rate essentially unchanged.
