Who can be held liable for a Michigan truck accident?

The truck driver

The most obvious defendant. A commercial driver can be personally liable for:

• Speeding, tailgating, unsafe lane changes, and other basic negligence.
• Driving while fatigued or in violation of federal hours-of-service rules (49 C.F.R. Part 395).
• Distracted driving — texting, dispatch apps, in-cab paperwork.
• Impairment — a violation of Michigan OWI law (MCL 257.625) or federal drug/alcohol regulations (49 C.F.R. Part 382).

The motor carrier (trucking company)

A motor carrier is liable in two independent ways:

1. Vicariously, under the doctrine of respondeat superior — the carrier is legally responsible for its driver's negligence committed within the scope of employment.

2. Directly, for its own conduct:

• Negligent hiring — putting a driver on the road without checking the PSP driving record, prior DOT violations, or CDL status.
• Negligent training and supervision — failing to train on cargo securement, defensive driving, or hours-of-service compliance.
• Negligent retention — keeping a driver on staff after prior crashes, positive drug tests, or logbook violations.
• Negligent entrustment — permitting an unqualified driver to operate a specific truck.
• Systemic violations — dispatch schedules that force hours-of-service violations, or maintenance shortcuts.

The truck or trailer owner

Under Michigan's owner-liability statute (MCL 257.401), the owner of a motor vehicle is liable for injuries caused by its negligent operation with the owner's consent. In truck cases, that pulls in leasing companies, owner-operators, and trailer owners.

Federal leasing rules layer additional liability on top. Under 49 C.F.R. § 376.12(c)(1), the motor carrier that displays its DOT numbers and placards has "exclusive possession, control, and use" of the leased equipment — meaning the carrier is legally responsible even if the truck is titled to a small owner-operator LLC. This is often called "logo liability."

Shippers, cargo loaders, and freight brokers

A significant number of truck crashes have their real root cause in the cargo, not the driver:

• Improper loading — unbalanced weight distribution, overloading beyond gross-vehicle-weight limits.
• Failure to secure — violations of the cargo-securement rules at 49 C.F.R. § 393, Subpart I.
• Hazardous materials — improper placarding, defective containers, or violation of 49 C.F.R. Parts 171-180.

Freight brokers — the middlemen who match shippers with carriers — can also be liable under emerging federal law for hiring a motor carrier that had unsatisfactory safety ratings, prior violations, or inadequate insurance. Whether a broker claim is preempted by the Federal Aviation Administration Authorization Act is an evolving area, and recent decisions have permitted these claims in personal injury cases.

Maintenance contractors and parts manufacturers

When mechanical failure caused or contributed to the crash — a wheel separation, a brake failure, a tire blowout, a steering defect — the liability chain extends to whoever last worked on that component and whoever made it:

• Third-party truck-repair shops.
• Tire dealers and installers.
• Brake, steering, and lighting component manufacturers — under Michigan's product-liability statute, MCL 600.2946 and MCL 600.2949.

Government entities

A public-agency defendant — MDOT, a county road commission, a city, or a school district that owns a truck involved in the crash — is possible but heavily regulated:

• Governmental Tort Liability Act (MCL 691.1401 et seq.) — narrow exceptions to immunity, including the highway exception (MCL 691.1402) and motor-vehicle exception (MCL 691.1405).
• 120-day written notice requirement under MCL 691.1404 — missing it is fatal.

Michigan's comparative-fault rule

Michigan uses modified comparative fault under MCL 600.2959 and MCL 500.3135(2)(b). If you are more than 50% at fault for the crash, you cannot recover noneconomic damages (pain and suffering). If you are 50% or less at fault, your recovery is reduced by your percentage of fault. Because truck cases often involve multiple defendants, the jury allocates a percentage of fault to each. Naming every proper defendant is what keeps your allocated share as low as possible.
