Truck Accident Laws in Michigan (2026): Deadlines & Liability

A truck accident in Michigan combines two bodies of law: Michigan's own injury rules (the filing deadline, the fault rule, and the state's distinctive no-fault auto system) and a thick layer of federal trucking regulation that governs how commercial carriers and their drivers must operate. Because Michigan is a no-fault state, the path to a lawsuit against an at-fault trucker runs through a statutory injury threshold, and because the truck is a commercial vehicle, federal safety rules often supply the evidence of who was negligent.

This page explains the Michigan deadlines and liability rules that apply after a crash with a semi, box truck, or other commercial vehicle, then the uniform federal rules that shape every interstate trucking case. It is general legal information, not legal advice.

What is the deadline to sue after a Michigan truck accident?

Michigan's statute of limitations for personal injury, including injuries from a truck crash, is three years from the date of the accident under MCL 600.5805. Wrongful-death claims arising from a fatal crash are governed by the same three-year period, generally running from the date of death, and must be brought by the personal representative of the estate.

Three years can disappear faster than it sounds. A wrongful-death suit cannot be filed until the probate court appoints a personal representative and issues Letters of Authority, which can take weeks. Evidence in a trucking case, discussed below, can be overwritten in days. Treat the deadline as a hard wall and act well before it.

Michigan's fault rule: how shared blame affects recovery

Michigan applies a comparative-fault rule under MCL 600.2959, and the statute treats two kinds of damages differently. For noneconomic damages, the pain, suffering, and loss of enjoyment of life, Michigan is a modified comparative-fault state with a 51% bar: if your share of fault is greater than the combined fault of everyone else, you recover nothing for noneconomic loss.

Economic damages work differently. Your recovery for medical bills, lost wages, and other out-of-pocket losses is reduced in proportion to your fault, but it is not cut off at the 50% line. Even a plaintiff found more than half at fault can still recover a reduced share of economic damages. In practice this means a trucking defendant cannot escape all liability simply by pinning a majority of blame on the injured person, though doing so wipes out the pain-and-suffering portion of the claim.

No-fault and the threshold to sue in Michigan

Michigan is one of the nation's strongest no-fault states. After a crash, your own auto policy pays personal injury protection (PIP) benefits for medical care and certain wage loss regardless of who caused the wreck. The 2019 no-fault reform (effective July 2020) ended mandatory unlimited PIP and replaced it with a menu of coverage tiers: unlimited, $500,000, $250,000, a $50,000 option for those on Medicaid, and an opt-out for drivers enrolled in Medicare. Every policy still carries mandatory property protection insurance as well.

Because PIP is the first source of medical payment, you cannot simply sue the at-fault trucker for pain and suffering after any crash. Under MCL 500.3135, a person remains subject to tort liability for noneconomic loss only if the injured person suffered death, serious impairment of body function, or permanent serious disfigurement. A serious impairment of body function is one that is objectively manifested (observable or perceivable by someone other than the injured person), involves an important body function, and affects the person's general ability to lead a normal life.

Most people seriously hurt by an 80,000-pound truck clear this threshold. Documented fractures, surgical injuries, traumatic brain injuries, and herniated discs confirmed by imaging routinely qualify. But the threshold is a genuine gatekeeper, which is one reason objective medical documentation matters so much in a Michigan truck case. Economic damages beyond your PIP limits, such as excess wage loss, may also be recoverable from the at-fault party.

Damage caps in Michigan

Michigan does not cap ordinary personal-injury damages in a standard motor-vehicle case. Economic damages (medical expenses and lost earnings) and noneconomic damages (pain and suffering) in a typical truck-crash claim are not subject to a statutory ceiling, subject to the comparative-fault and no-fault rules above. Statutory caps in Michigan apply mainly to specific contexts such as medical-malpractice and product-liability noneconomic damages, which are generally not the framework for a routine truck-collision claim.

Minimum insurance in Michigan

Michigan requires every auto policy to carry at least 50/100/10 in bodily-injury and property-damage liability ($50,000 per person, $100,000 per accident, $10,000 property damage), plus mandatory PIP at the tier you select and mandatory property protection insurance. These are the floors for ordinary drivers. Commercial trucks are subject to far higher federal requirements, covered next.

Federal FMCSA rules that govern trucking

Interstate commercial trucking is regulated by the Federal Motor Carrier Safety Administration (FMCSA) under Title 49 of the Code of Federal Regulations. These rules apply nationwide and frequently supply the proof of negligence in a truck case:

• Hours of service (49 CFR Part 395): A property-carrying driver may drive a maximum of 11 hours after 10 consecutive hours off duty, may not drive beyond the 14th hour after coming on duty, must take a 30-minute break after 8 hours of driving, and may not drive after 60 hours on duty in 7 days or 70 hours in 8 days.
• Electronic logging devices (ELDs): Most drivers must record their hours with an ELD that automatically captures driving time, making falsified-logbook fatigue easier to prove.
• Driver qualification and CDL: Drivers must hold a valid commercial driver's license and meet medical and qualification standards under the driver-qualification rules.
• Drug and alcohol testing: Carriers must conduct pre-employment, random, post-accident, and reasonable-suspicion testing.
• Vehicle maintenance and inspection (49 CFR Part 396): Carriers must systematically inspect, repair, and maintain their vehicles and keep records.

A logbook showing too many hours behind the wheel, a skipped inspection, or a missed drug test can become central evidence that the driver or carrier was negligent.

Who can be held liable after a truck accident

A truck crash routinely produces several defendants, often corporate, which is a key difference from a typical car accident. Depending on the facts, the responsible parties can include the truck driver; the motor carrier (both vicariously for the driver's on-the-job conduct and directly for negligent hiring, training, supervision, or retention); a freight broker or shipper; the company that loaded or secured the cargo; and the manufacturer of a defective part such as a brake or tire.

Identifying every potential defendant matters because each may carry separate insurance, and because a carrier's own safety failures (pressuring drivers past their hours, ignoring maintenance) can be independent grounds for liability beyond the driver's mistake.

Federal minimum insurance for trucks

Under 49 CFR 387.9, an interstate for-hire motor carrier hauling general (nonhazardous) freight in a vehicle of 10,001 pounds or more must maintain at least $750,000 in public-liability coverage. Carriers hauling certain hazardous materials must carry far more, up to $5,000,000. These federal minimums dwarf typical car-insurance limits and are one reason serious truck claims are valued differently from ordinary car-crash claims.

Preserving evidence after a truck crash

Trucking evidence is perishable. A truck's engine control module (its onboard "black box") can record speed, braking, and throttle data; the driver's ELD and logbooks record hours; and the carrier's maintenance and inspection records can show neglect. Much of this data can be overwritten or lawfully discarded on a routine retention schedule within weeks. A prompt written preservation (spoliation) letter to the carrier, asking it to retain the ECM data, ELD records, dispatch records, and maintenance files, helps keep that evidence intact.

Also preserve the basics on your side: the police crash report, photographs of the vehicles and scene, the names of witnesses, and complete medical records documenting your injuries.

How to evaluate a Michigan truck-accident claim

Most personal-injury attorneys handle truck cases on a contingency-fee basis (the fee is a percentage of any recovery) and offer a free initial consultation, so an early conversation usually costs nothing. No lawyer can promise a particular outcome or dollar amount; the value of any claim depends on the facts, the injuries, the available insurance, and the fault analysis.

The practical priorities after a Michigan truck crash are to get medical care and document your injuries, report the crash and obtain the police report, open your PIP claim with your own insurer, preserve evidence quickly, and keep the three-year deadline firmly in view.
