Illinois does not have a motorcycle helmet law. No rider or passenger, of any age, is required by state law to wear a helmet on an Illinois road. What the state does require is eye protection, a lighted headlamp, a working muffler, and a handful of equipment rules that catch riders off guard every season. Here is what the law actually says, and how it can affect an injury claim if another driver hits you.
Does Illinois Have a Helmet Law?
No. Illinois is one of a small handful of states with no motorcycle helmet requirement at all. The Vehicle Code section setting out special equipment for riders, 625 ILCS 5/11-1404, covers eye protection and says nothing about helmets. There is no separate rule for younger riders either, so no helmet mandate applies to minors.
That makes helmet use a personal decision in Illinois, not a legal one. Federal crash researchers consistently find that helmets substantially cut the risk of death and serious head injury, which is why state and federal safety agencies recommend them even though Illinois does not require them.
Eye Protection Is Required, Even When a Helmet Is Not
This is the rule riders most often miss. Under 625 ILCS 5/11-1404, the operator of a motorcycle, motor driven cycle, or moped and every passenger must be protected by glasses, goggles, or a transparent shield. Four things satisfy that: glasses or sunglasses made of shatter-resistant material, goggles that protect the eyes from the front and the sides, a windshield attached to the bike that extends above eye level, or a face shield covering the eyes and face. Two details catch people out: contact lenses do not qualify under the statute, and the requirement covers passengers, not just the operator.
Illinois Motorcycle Equipment and Operating Rules
The rest of the rules governing how a bike is equipped and ridden sit in the Illinois Vehicle Code:
- Headlamp at all times: every motorcycle must show at least one lighted white lamp visible for 500 feet, day and night (625 ILCS 5/12-201(a))
- Handgrip height: handlebar grips cannot sit higher than the operator’s head in a normal seated position (625 ILCS 5/11-1403(c))
- One hand on the bars: at least one hand on a handlebar grip whenever the bike is moving (625 ILCS 5/11-1403(d))
- Seating: ride astride the permanent seat, facing forward, one leg on each side (625 ILCS 5/11-1403(a) and (b))
- Passengers: only on a permanent seat or a seat firmly attached at the rear or side, and only if the passenger can rest a foot on the footrest while the bike is in motion (625 ILCS 5/11-1403(a) and (e))
- Mirror: the general motor-vehicle mirror rule applies to your bike, so you need a mirror showing 200 feet of highway to the rear (625 ILCS 5/12-502)
- Muffler: an adequate muffler in constant operation, no cutouts or bypasses, no modifications that amplify noise beyond the original equipment (625 ILCS 5/12-602)
- Helmet intercoms: a helmet with a two-way electronic intercom system is expressly allowed (625 ILCS 5/11-1403.3)
Illinois sets no minimum passenger age, and the footrest rule does that work in practice, since a child too small to reach a footrest cannot legally be carried. Trail and off-highway riding is separate, governed by different Vehicle Code provisions plus forest preserve, park district, and county ordinances.
Lane Splitting and Lane Filtering in Illinois
Illinois has not authorized lane splitting. Every vehicle must be driven as nearly as practicable entirely within a single lane (625 ILCS 5/11-709(a)), and a two-wheeled vehicle passing on the left cannot then pass on the right of a vehicle going the same direction unless an unobstructed lane is available for the maneuver (625 ILCS 5/11-703(c)). Riding between lanes of stopped or slow traffic falls outside those rules.
Two motorcycles riding abreast in one lane is a separate question, and the Vehicle Code neither authorizes it nor prohibits it. Our breakdown of lane filtering in Illinois goes deeper.
Licensing and Insurance for Illinois Riders
Illinois classifies motorcycle licenses by engine size. A Class L license covers a motor-driven cycle under 150cc; a Class M license covers anything 150cc or larger. First-time applicants without a valid Illinois license take a vision screening, written basic and motorcycle exams, and a road test that is waived with an IDOT Rider Course completion card.
Motorcycles are also subject to Illinois mandatory liability insurance. The statutory minimums are $25,000 for bodily injury or death of one person, $50,000 for two or more people in one crash, and $20,000 in property damage (625 ILCS 5/7-203). Those limits go fast in a motorcycle case, which is why underinsured motorist coverage is worth a look before you need it.
Riding Without a Helmet and Your Injury Claim
Because Illinois never required a helmet, choosing not to wear one violates no law and is not evidence that you caused a crash. Insurers still raise it, usually by arguing a head injury would have been less severe with a helmet, which is an attempt to shift a share of fault onto the rider.
Illinois uses modified comparative fault, so any share of fault assigned to you comes straight off your damages, and recovery is barred only once your share passes 50% (735 ILCS 5/2-1116). A rider found 20% at fault on a $100,000 case recovers $80,000. Most Illinois personal-injury claims also have to be filed within two years of the injury (735 ILCS 5/13-202), so waiting to see how recovery goes can cost you the claim.
One deadline is much shorter, and it catches riders out. If the vehicle that hit you belonged to a city, village, township, park district, transit agency, or another local public entity, or the crash involved a road defect on a road one of those entities controls, you have one year to sue rather than two (745 ILCS 10/8-101). Claims against the State of Illinois run through the Court of Claims on their own schedule. Pinning down who owned the vehicle or the road in the first weeks is what protects that shorter window.

Frequently Asked Questions
Is it illegal to not wear a helmet on a motorcycle in Illinois?
No. Illinois has no motorcycle helmet requirement for operators or passengers of any age, and no separate helmet rule for minors. Eye protection is required (625 ILCS 5/11-1404), but headgear is not.
Does Illinois require eye protection on a motorcycle?
Yes. Both the operator and any passenger must be protected by glasses, goggles, or a transparent shield. Shatter-resistant glasses or sunglasses, goggles that protect from the front and sides, a windshield attached to the bike that extends above eye level, or a face shield all qualify. Contact lenses do not (625 ILCS 5/11-1404).
Is lane splitting legal in Illinois?
No. Illinois requires vehicles to stay within a single lane (625 ILCS 5/11-709(a)) and limits when a two-wheeled vehicle can pass on the right (625 ILCS 5/11-703(c)). Riding between lanes of traffic is not authorized.
Can not wearing a helmet reduce my motorcycle accident settlement in Illinois?
It should not establish fault for the crash, because no law required a helmet. Insurers may still argue helmet use would have limited the injury. Illinois reduces damages by a plaintiff’s share of fault and bars recovery only above 50% (735 ILCS 5/2-1116), so how that argument is answered can matter.
What license do I need to ride a motorcycle in Illinois?
A Class M license for a motorcycle of 150cc or more, or a Class L license for a motor-driven cycle under 150cc, issued by the Illinois Secretary of State.
Does Illinois have a bicycle helmet law?
Not at the state level. Some Illinois municipalities have their own ordinances, often aimed at younger riders, so local rules are worth checking.
How long do I have to file a motorcycle accident claim in Illinois?
Generally two years from the date of the injury (735 ILCS 5/13-202). If a city, village, township, park district, transit agency, or other local public entity is involved, whether as the driver or as the government that controls the road, the window drops to one year (745 ILCS 10/8-101). Identify who owned the vehicle and the road early so you do not lose the shorter deadline.
