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

A Missouri truck accident is governed by two layers of law: Missouri's own injury rules (the filing deadline and the state's fault rule) and the federal regulations that control how commercial carriers and drivers must operate. Missouri is a traditional at-fault (tort) state, not a no-fault state, so an injured person pursues the at-fault driver and the motor carrier directly. Because the other vehicle is a commercial truck, federal safety rules often supply the evidence of negligence.

This page explains the Missouri deadlines and liability rules that follow 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 Missouri truck accident?

Missouri's general personal-injury statute of limitations is five years, set by RSMo 516.120, which covers an action "for any other injury to the person or rights of another" not otherwise specified. A truck-crash injury claim generally must be filed within five years of the date of the crash. That is one of the more generous deadlines in the country, but it is not a reason to wait.

Wrongful death is different. Under RSMo 537.100, a wrongful-death action arising from a fatal crash must be commenced within three years after the death. Because the deadlines differ, families pursuing both an injury and a death claim should track each one separately.

Even five years is a hard cutoff, and trucking evidence can be overwritten within weeks. The practical timeline for investigating a truck case usually runs much faster than the formal deadline.

Missouri's fault rule: pure comparative fault

Missouri follows pure comparative fault. The Missouri Supreme Court adopted the rule in Gustafson v. Benda, 661 S.W.2d 11 (Mo. banc 1983), directing courts to apply pure comparative fault in accordance with the Uniform Comparative Fault Act and abolishing the old all-or-nothing contributory-negligence bar.

Under pure comparative fault there is no percentage cutoff. A plaintiff found 30% at fault recovers 70% of the damages, and even a plaintiff found 99% at fault can still recover 1%. This is more favorable to injured plaintiffs than the modified-comparative rules used in most states, where being more than half at fault wipes out recovery entirely. In a truck case, where the carrier's own regulatory violations frequently shift fault toward the trucking side, pure comparative fault means an injured person is not shut out even if some blame is assigned to them.

No-fault status: Missouri is an at-fault state

Missouri is not a no-fault state. It uses the traditional tort (at-fault) system, which means there is no mandatory personal injury protection (PIP) and no statutory injury threshold to clear before filing suit. After a crash, the injured person makes a claim against the at-fault driver and the motor carrier, and ultimately their liability insurers, and may recover both economic and noneconomic damages by proving the other side's negligence. This removes the threshold hurdle that exists in no-fault states, but it places the full burden of proving fault on the injured party.

Damage caps in Missouri

Missouri does not cap ordinary compensatory damages in a standard truck-injury case. Economic damages (medical expenses, lost earnings, future care) and noneconomic damages (pain and suffering) in an ordinary negligence case are not subject to a statutory cap. A separate, narrower cap on noneconomic damages applies in medical-malpractice cases, which is a different category from a truck crash.

Punitive damages are different, and the limit on them is contested. RSMo 510.265 caps punitive damages at the greater of $500,000 or five times the net amount of the judgment awarded against that defendant. The statute carves out two situations of its own: the cap does not apply when the state of Missouri is the plaintiff requesting punitive damages, or when the defendant pleads guilty to or is convicted of a felony arising out of the same acts or omissions pleaded by the plaintiff.

The larger limit is constitutional. In Lewellen v. Franklin, 441 S.W.3d 136 (Mo. banc 2014), the Missouri Supreme Court held that the RSMo 510.265 cap is unconstitutional under article I, section 22(a) of the Missouri Constitution, because the right to a jury trial as it stood in 1820 included the right to have the jury, rather than the legislature, determine the amount of punitive damages. That reasoning ties the cap's force to whether the claim being tried is one that carried a jury-trial right in 1820, so whether the cap can constitutionally be applied to a particular truck-crash claim is a live question rather than a fixed ceiling. Because these rules are technical and still being litigated, they are worth raising with counsel early.

Minimum insurance in Missouri

Missouri requires every driver to carry at least 25/50/25 in liability coverage ($25,000 bodily injury per person, $50,000 per accident, $25,000 property damage), plus uninsured-motorist coverage of $25,000 per person and $50,000 per accident, according to the Missouri Department of Revenue. That is the floor 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 (pushing 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 Missouri 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 Missouri truck crash are to get medical care and document your injuries, report the crash and obtain the police report, identify the insurers involved, preserve evidence quickly, and keep the filing deadlines firmly in view.
