Michigan Car Accident Comparative Fault: The 50% Rule

In a Michigan car accident claim, exactly 50% fault is different from more than 50% fault. For noneconomic damages such as pain and suffering, a person more than 50% at fault is barred from recovery. At 50% or less, fault can reduce the award, but does not itself impose that bar.

Apply the rule to the correct category of damages

Michigan’s civil jury instructions for motor vehicle cases explain the distinction between reducing noneconomic damages and barring them when the injured person’s fault exceeds 50%. A claimant must still satisfy the other requirements for noneconomic recovery; a favorable fault percentage alone is insufficient.

Do not turn this into a blanket statement that someone at 51% fault loses every insurance benefit or every type of claim. PIP benefits, property damage, and different economic-loss claims have their own rules and must be analyzed separately.

An example of reduction, not a case-value estimate

Suppose a jury determines otherwise recoverable noneconomic damages of $100,000 and assigns the injured person 30% fault. A 30% reduction leaves $70,000. At exactly 50% fault, the same illustrative amount would be reduced to $50,000 rather than automatically eliminated. These figures illustrate the calculation only; they do not predict a settlement or decide whether an actual injury meets the legal threshold.

Fault percentages depend on evidence

• Traffic signals, signs, lane positions, turning movements, and the sequence leading to impact.
• Original photographs, video, and witness observations of the approach to the collision.
• Speed, following distance, visibility, and weather evidence relevant to the actual event.
• Police information and citations considered alongside the other evidence.
• Each party’s conduct and its causal connection to the collision, rather than isolated mistakes unrelated to the crash.

Challenge an unsupported allocation with the underlying records

An insurer’s proposed percentage is a position in the claim, not an automatic final determination. Ask which facts support it. Keep an accurate account, including facts that may be unfavorable, and preserve evidence that can test the competing explanations.

Our explanation of Michigan’s no-fault system addresses why insurance benefits and a negligence claim should not be collapsed into one question. Review both the fault evidence and the specific damages being pursued before accepting an offer.

This article provides general information, not legal advice. The applicable law, policy terms, and deadlines depend on the facts of your case.

Am I automatically barred at exactly 50% fault?

No. For motor-vehicle noneconomic damages, the bar applies when your fault is more than 50%. At exactly 50%, the otherwise recoverable award is reduced.

Does being 51% at fault eliminate every PIP benefit?

No. Do not apply the noneconomic-damages bar as a blanket PIP rule. Benefits have separate eligibility and coverage requirements.

Is the insurer’s fault percentage final?

No. It can be disputed with evidence. The ultimate determination depends on the claim and its resolution.
