Massachusetts treats an injured motorcyclist differently from an injured car driver at almost every stage of an insurance claim, and the biggest difference is one most riders discover only after a crash: the no-fault system that pays medical bills for car occupants does not pay them for riders. That single gap reshapes everything else, so this guide starts there and works outward through the helmet law, comparative fault, the coverages that protect riders, and the road rules that decide motorcycle cases.
The One Rule That Changes Everything: No PIP for Riders
Massachusetts is a no-fault state for motor vehicle injuries. Every auto policy must include Personal Injury Protection, or PIP, which pays up to $8,000 in medical expenses and lost wages regardless of who caused the crash. The requirement comes from G.L. c. 90, § 34M, and the benefits are defined in G.L. c. 90, § 34A.
Motorcyclists sit outside that system. The mechanism is easy to miss because the statutes never say the word “motorcycle.” A motorcycle must be registered and insured like any other motor vehicle, but the Division of Insurance has provided by regulation that insurers need not include PIP coverage for the owners, operators, or passengers of motorcycles in the policies that cover them. So the PIP component of a bike policy covers only pedestrians the motorcycle might strike, not the people on the bike, and the standard Massachusetts auto policy likewise excludes PIP for anyone injured while occupying a motorcycle, closing off the rider’s own car policy as a fallback.
The practical result: a rider hurt in a crash has no no-fault medical coverage at all from any motor vehicle policy.
There is a significant upside hidden in that gap. Under G.L. c. 231, § 6D, a person injured in a motor vehicle accident generally cannot recover pain and suffering damages unless reasonable medical expenses exceed $2,000 or the injury involves death, a fracture, permanent and serious disfigurement, or certain sight or hearing loss. That tort threshold is the trade-off for guaranteed PIP benefits. Because motorcyclists receive no PIP benefits, the threshold does not stand in their way: an injured rider can pursue a liability claim against the at-fault driver for the full range of damages, including pain and suffering, without first clearing $2,000 in medical bills. That direct route to a tort claim matters most in lower-impact cases and removes a standard defense argument available in car cases.
What the PIP Gap Means for Your Medical Bills
Since no PIP check is coming, an injured rider’s bills get paid, if at all, from three sources.
Health insurance first. Your health plan is the front-line payer for crash treatment. Use it from the first ambulance ride. Expect the plan, whether private, MassHealth, or Medicare, to assert a lien against any settlement you later recover; that is normal and gets negotiated at the end of the case.
MedPay if you bought it. Medical payments coverage is an optional add-on to Massachusetts motorcycle policies, typically sold in amounts from $5,000 to $25,000 or more. It pays medical expenses for the rider and passenger regardless of fault, which makes it the closest substitute for the PIP that riders do not get, and it is inexpensive relative to what it does.
The liability claim last. The at-fault driver’s bodily injury coverage ultimately pays for medical expenses, lost earnings, and pain and suffering, but only at the end of the claim, in one lump settlement or judgment. Do not expect the other driver’s insurer to pay bills as they come in.
The Helmet Law and How It Plays in a Claim
Massachusetts has a universal helmet law. G.L. c. 90, § 7 requires every operator and passenger, including a sidecar passenger, to wear protective headgear meeting the Registrar’s standards. The statute’s only carve-out is for riders 18 or older in a properly permitted public parade; there is no adult exemption for ordinary riding. Operators without a windshield must also wear eye protection.
What happens in a civil case if a rider was not wearing a helmet? Massachusetts does not treat a statutory violation as automatic negligence. Violating a safety statute is “some evidence” of negligence as to the harms the statute was meant to prevent, and G.L. c. 231, § 85 provides that a plaintiff’s statutory violation is evidence of negligence but shall not, as a matter of law and for that reason alone, bar recovery. A defendant can point to helmet nonuse, but it matters only to the extent the defense connects it causally to the injuries. Nonuse has nothing to do with a broken leg or road rash on the arms; it becomes a genuine fight only where head or facial injuries are claimed, and even then the defense generally needs expert testimony that a helmet would have made a difference. Expect insurers to raise nonuse whenever the record allows it, which is one more reason the helmet stays on.
Comparative Negligence and the Bias Problem
Massachusetts follows modified comparative negligence under G.L. c. 231, § 85. An injured person can recover as long as their share of fault is not greater than the combined fault of the defendants: 50 percent or less in a two-party case. Recovery is reduced by the plaintiff’s percentage, so a rider found 20 percent at fault on $100,000 in damages collects $80,000, and at 51 percent recovers nothing. The statute also gives the plaintiff a presumption of due care, and comparative negligence is an affirmative defense the defendant must plead and prove.
Those percentages are exactly where motorcycle claims get fought. Adjusters routinely argue that the rider was speeding, weaving, or invisible, because fault percentages translate directly into dollars, and jurors bring their own assumptions about motorcyclists that insurers price into their offers. The factual record is the antidote: crash reconstruction, skid and gouge marks, damage patterns, independent witnesses, and video from doorbell and dash cameras. The common crash patterns cut the other way more often than the stereotype suggests. The classic Massachusetts motorcycle case is a car turning left across the rider’s path at an intersection, where the driver “looked but did not see” the oncoming bike. Dooring is another recurring pattern: G.L. c. 90, § 14 prohibits opening a vehicle door unless it is reasonably safe to do so without interfering with other traffic, and a rider taken down by a flung door has a statutory violation to point to. In both patterns the driver, not the rider, made the critical error.
The Coverages That Actually Protect Riders
Because the no-fault safety net is missing, the insurance choices a rider makes before a crash matter more than they do for drivers. Four coverages carry the load.
- The at-fault driver’s bodily injury coverage. Massachusetts requires only $20,000 per person and $40,000 per accident in compulsory limits, and serious motorcycle injuries exhaust a $20,000 policy almost immediately, so the other driver’s limits often cap what a liability claim alone can produce.
- Uninsured motorist coverage (UM). Required on every Massachusetts policy, UM pays when the at-fault driver has no insurance or cannot be identified, as in a hit-and-run. For a rider, UM on the motorcycle policy is the claim that saves the case when the driver flees or is uninsured.
- Underinsured motorist coverage (UIM). Optional but essential for riders. UIM pays when the at-fault driver’s limits are too low for the injuries, up to the difference between the driver’s bodily injury limits and your own UIM limits: a rider with $100,000 in UIM hit by a minimally insured driver can recover the $20,000 liability limit plus up to $80,000 from their own carrier. High UM/UIM limits are the single most important purchase a Massachusetts rider can make.
- MedPay. As described above, the optional no-fault substitute that pays medical bills regardless of fault.
One limit to know: Massachusetts prohibits stacking. For policies effective after January 1, 1989, G.L. c. 175, § 113L(5) bars combining UM or UIM limits from multiple vehicles or policies into a larger pool for one accident. A rider who insures a motorcycle and two cars cannot add the three UM limits together, so the limit you select on each policy, not the number of policies you hold, is the number that matters.
UM and UIM claims are contract claims against your own insurer, resolved by arbitration rather than a jury trial when the parties disagree on value, and a UIM claim requires your carrier’s consent before you settle with the at-fault driver. Missing that consent step can forfeit the coverage, so involve counsel before signing anything.
Lane Splitting and Other Road Rules
Lane splitting, riding between lanes of slowed or stopped traffic, is illegal in Massachusetts. G.L. c. 89, § 4A requires every vehicle to be driven entirely within a single lane and specifically provides that motorcycle operators shall not pass any other motor vehicle within the same lane, except another motorcycle. The same section permits riding two abreast, but no more, and requires single file when passing. Bills to legalize lane splitting or lane filtering have been filed in past legislative sessions and none has become law, so as of 2026 the prohibition stands. In a civil claim, a rider who was splitting lanes at the time of the crash hands the insurer a statutory violation to argue as comparative negligence, with the same “evidence of negligence” treatment described above for helmet nonuse.
The rules that protect riders deserve equal billing. Motorcycles are entitled to the full use of a lane, and drivers owe them the same duties owed to any vehicle. The dooring statute, G.L. c. 90, § 14, protects passing riders in urban traffic. And the deadline that governs everything: a Massachusetts personal injury claim must be filed within three years of the crash under G.L. c. 260, § 2A. Wrongful death claims carry their own three-year period, and claims against public entities involve shorter presentment deadlines.

After a Crash: Steps That Protect the Claim
- Get medical care immediately and follow through. Adrenaline masks injuries, and gaps in treatment become arguments that the injuries were minor.
- Call the police and make sure a report is filed. The crash report anchors the liability investigation and identifies the other driver’s insurer.
- Document the scene if you are able. Photograph vehicle positions, damage, debris, skid marks, and the roadway, and get witness names and numbers. Motorcycle cases turn on physical evidence more than most.
- Preserve the bike and your gear. Do not repair or discard the motorcycle, helmet, or riding gear until they are photographed and inspected. Helmet damage and gear abrasion are evidence of impact forces.
- Notify your own insurer promptly. UM, UIM, and MedPay all require timely notice, and a hit-and-run UM claim demands prompt reporting.
- Do not give a recorded statement to the other driver’s insurer. You are not obligated to, and early statements get used against you on comparative fault.
- Track everything. Bills, mileage, missed work, and the day-to-day limitations that become the pain and suffering component of the claim, including biker-specific harms such as road rash scarring, degloving injuries, and nerve damage that outlast the fractures.
Frequently Asked Questions
Does PIP cover motorcycle riders in Massachusetts?
No. By Division of Insurance regulation, motorcycle policies need not provide PIP for the bike’s owner, operator, or passengers, and the standard auto policy excludes PIP for anyone injured while occupying a motorcycle. Riders rely on health insurance, optional MedPay, and the liability or UM/UIM claim.
Can I sue without $2,000 in medical bills?
Yes. The $2,000 threshold in G.L. c. 231, § 6D is the trade-off for PIP benefits. Because motorcyclists receive no PIP, the threshold does not apply to them, and an injured rider can bring a full tort claim against the at-fault driver regardless of the size of the medical bills.
Does not wearing a helmet hurt my case?
It can, but it is not fatal. Violating the helmet law in G.L. c. 90, § 7 is evidence of negligence under G.L. c. 231, § 85, not an automatic bar to recovery. It matters only where the defense can causally connect nonuse to the injuries claimed, generally head or facial injuries, and expert testimony is typically needed to make that connection.
Is lane splitting legal in Massachusetts?
No. G.L. c. 89, § 4A requires vehicles to stay entirely within a single lane and bars motorcycles from passing any other motor vehicle within the same lane, except another motorcycle. Riding two abreast is allowed; three or more is not. Legalization bills have been filed in past sessions but none has passed as of 2026.
What if the driver who hit me is uninsured or takes off?
You make an uninsured motorist claim under your own motorcycle policy. UM coverage is mandatory in Massachusetts and applies to uninsured drivers and unidentified hit-and-run drivers alike. Report a hit-and-run to police and your insurer promptly, since late notice is a common basis for disputing these claims.
How long do I have to file a motorcycle injury lawsuit?
Three years from the date of the crash under G.L. c. 260, § 2A. Claims involving government defendants or minors follow different rules, and evidence degrades quickly, so the practical deadline for starting an investigation is far shorter than the legal one.
The Bottom Line
Massachusetts riders operate under different rules than drivers: no PIP safety net, direct access to a tort claim, a universal helmet law, and an insurance market that argues rider fault as a matter of routine. The riders who come through crashes financially intact are usually the ones who bought high UM/UIM limits and MedPay before they needed them.
