Comparative fault in a motorcycle accident is where most Michigan riders’ claims are quietly reduced, because a percentage assigned in an adjuster’s file rarely gets challenged unless someone challenges it. At Christensen Law, we handle these cases knowing the fault argument is coming before the insurer makes it. Riders face assumptions that car drivers do not.
How Does Comparative Fault Affect a Motorcycle Accident Claim?
In Michigan, being partly responsible for a crash reduces what a rider recovers rather than eliminating the claim, until the rider’s share passes 50 percent. Past that point, non-economic damages such as pain and suffering are barred entirely, while economic losses may still be reduced instead.
- Damages drop in proportion to the rider’s percentage of fault.
- More than 50 percent fault bars noneconomic damages.
- Insurers routinely assign riders more fault than the evidence supports.
Key Takeaways
- Michigan uses a modified comparative fault rule that reduces damages by the injured person’s share of responsibility.
- A person found more than 50 percent at fault cannot recover noneconomic damages.
- Motorcycles are not motor vehicles under Michigan no-fault, so PIP access depends on a motor vehicle being involved.
- Riding legally without a helmet does not bar a claim, though insurers argue it affects injury severity.
- Physical evidence and reconstruction usually carry more weight than either party’s account.
What Does Michigan Law Say About Shared Fault in a Motorcycle Crash?
Michigan applies a modified comparative negligence standard in motorcycle cases, set out in MCL 600.2959. Damages are reduced in proportion to the injured person’s share of the total fault.
The statute draws a hard line at more than 50 percent. A rider found more than half responsible cannot recover non-economic damages at all, although economic damages may still be reduced rather than barred outright.
That structure explains the arithmetic behind most negotiations. An insurer arguing 40 percent fault is arguing for a 40 percent discount, and one arguing 51 percent is arguing the pain and suffering claim disappears.
Why Riders Get Assigned More Fault Than They Deserve
Motorcycle claims carry a bias that shows up early. Adjusters, and sometimes jurors, arrive with assumptions about speed and risk-taking that have nothing to do with the crash in front of them.
The arguments we answer most often include:
- Assuming the rider was speeding, with no supporting data.
- Treating lane position as reckless when it was a lawful choice.
- Claiming the rider could have avoided a driver’s left turn across their path.
- Pointing to the absence of a helmet as evidence of general carelessness.
- Arguing that riding at night or in a group is inherently unsafe.
- Suggesting protective gear choices show indifference to risk.
Each of these is an assertion until it is supported. Event data from the other vehicle, reconstruction analysis, roadway evidence, and independent witnesses are what convert a fault argument into a fault finding, or defeat it.
Does Not Wearing a Helmet Reduce a Rider’s Recovery?
Riding legally without a helmet does not bar a claim, and it is not evidence that a rider caused a crash. Michigan permits it under conditions set out in MCL 257.658.
Under that section, an operator 21 or older may ride without a helmet if they have held a motorcycle endorsement for at least two years or completed an approved safety course, and carry at least $20,000 in first-party medical benefits coverage. Passengers 21 or older need comparable coverage in place.
Insurers still raise helmet non-use, but they raise it about injury rather than about liability. The argument is that particular head injuries would have been less severe, which is a medical question answered by treating physicians and medical opinion evidence.
Our discussion of Michigan’s helmet requirements covers what riders need in place to ride lawfully without one.
How Fault Interacts With Michigan No-Fault Benefits
Fault does not affect first-party benefits, which is a distinction worth holding onto. If a rider qualifies for Personal Injury Protection benefits, those are paid regardless of who caused the crash.
Access is the complication for riders. Motorcycles are not motor vehicles under Michigan’s no-fault act, so a rider generally reaches PIP benefits only where a motor vehicle was involved in the crash.
When one was, MCL 500.3114(5) sets the priority order, starting with the insurer of the owner or registrant of the motor vehicle involved, then that vehicle’s operator, then the rider’s own motor vehicle insurer. Our answer on whether motorcycles get no-fault benefits walks through that sequence.
FAQs About Comparative Fault in a Motorcycle Accident
An insurer proposes one during negotiation, but only a jury or judge determines it in a contested case. An adjuster’s number is an opening position rather than a finding.
Often yes, with a reduction reflecting your share of responsibility. Speeding matters most when it actually contributed to the crash, and less when a driver violated your right of way regardless of your speed.
Riding between lanes is not permitted in Michigan, and an insurer will use it. It does not automatically end a claim, though it strengthens the comparative fault argument considerably.
No. A citation is evidence a jury can consider, and civil fault is decided separately on the full record. Claims succeed without citations and fail with them.
Not before getting advice. Early recorded statements are commonly used to establish the fault percentage an insurer wants, and casual phrasing about speed or visibility is hard to walk back.

A fault percentage assigned early tends to stick unless somebody pushes back with evidence. If an insurer is blaming you for a crash you did not cause, that is worth challenging.
