One of the most damaging myths in personal injury law is this: "I was partly at fault for my accident, so I have no case." Missouri law says otherwise — and understanding why could be the difference between recovering substantial compensation and walking away with nothing.
Missouri follows a doctrine called pure comparative fault. Under this system, even if you share some responsibility for the accident that injured you, you are still entitled to recover compensation from the other at-fault parties. Your recovery is simply reduced in proportion to your share of the blame. If you were 30% at fault and the other driver was 70% at fault, you recover 70% of your damages — not zero.
This matters enormously in real Missouri accident cases. Insurance companies routinely argue that an injured person contributed to their own accident as a strategy to reduce or eliminate what they owe. Understanding how Missouri's comparative fault system actually works — and how fault percentages are determined — gives you the knowledge to push back. Taran & Associates, P.C. represents injured Missourians in exactly these disputes, and this guide explains the law as it applies to your situation.
Missouri Statute — RSMo § 537.765
Missouri's pure comparative fault rule is codified at RSMo § 537.765. The statute establishes that contributory fault does not bar a plaintiff's recovery — it only reduces the award. Missouri courts apportion fault by percentage among all parties (including the plaintiff), and each party's liability is reduced accordingly. There is no threshold below which a plaintiff is barred from recovering — even a plaintiff found 99% at fault may recover 1% of their proven damages from the other party.
Pure Comparative Fault vs. Modified Comparative Fault
Not every state handles shared fault the same way. Missouri's approach is among the most plaintiff-friendly in the country, but many injury victims don't realize this until they've already given up on a valid claim. Here is how the three main systems compare:
| System | Rule | Example: 60% at fault |
|---|---|---|
| Pure Comparative Fault Missouri | You can recover at any fault level. Your award is reduced by your percentage. | Recover 40% of damages. |
| Modified Comparative Fault (50% bar) | You can recover only if you are less than 50% at fault. | Barred from recovery entirely. |
| Modified Comparative Fault (51% bar) | You can recover only if you are 50% or less at fault. | Barred from recovery entirely. |
| Contributory Negligence | Any fault on your part bars recovery completely. | Barred from recovery entirely. |
The majority of states use a modified comparative fault model. Under those systems, if you are found to be 51% at fault — even in a case where the other party was 49% at fault — you collect nothing. Missouri rejected this approach and adopted the pure comparative fault model, which means partial fault never eliminates your right to recover.
This distinction has real consequences. A driver who failed to signal before a turn, a pedestrian who crossed mid-block, a slip-and-fall victim who was looking at their phone — all of these people may bear some share of responsibility for what happened to them. Under Missouri law, that partial responsibility reduces their compensation but does not erase it. Do not assume that because you were not perfectly careful, you have no claim. Let the law — not an insurance adjuster's framing — determine what you can recover.
How Fault Percentages Are Determined in Missouri
Comparative fault only works in practice if there is a fair and rigorous process for actually assigning those percentages. In Missouri, fault apportionment is based on evidence — and the evidence that gets gathered in the days and weeks after an accident shapes everything that follows.
Police Reports and Witness Statements
The responding officer's report is typically the first official record of how the accident occurred. It captures the officer's observations, whether any citations were issued, and — critically — the statements made by all drivers at the scene before anyone has had a chance to consult a lawyer. Witness statements collected at the scene or shortly after carry significant weight because they reflect what was actually observed, before memory fades or accounts get shaped by self-interest.
Physical Evidence: Skid Marks, Vehicle Positions, and Damage Patterns
The physical record left at an accident scene tells its own story. Skid marks indicate how fast vehicles were traveling and when braking began. Final resting positions show the direction and force of impact. Damage patterns on vehicle bodies reveal which areas sustained contact first, helping reconstruct the sequence of events. This evidence disappears quickly once roads are cleared and vehicles are moved — which is why documenting the scene immediately is so important.
Traffic Camera and Surveillance Footage
Intersections in Missouri's larger cities — including Cape Girardeau along the I-55 corridor — are often monitored by traffic management systems. Nearby businesses frequently have exterior cameras that capture street-level events. This footage can be dispositive, showing exactly who had the green light, how fast each vehicle was traveling, and whether any driver was distracted. Most surveillance footage is overwritten within 30 to 90 days. An attorney can send a preservation demand immediately to prevent evidence destruction.
Expert Accident Reconstruction
In serious cases, attorneys retain accident reconstruction specialists who apply physics and engineering analysis to the physical evidence. These experts produce formal reports — and can testify at trial — establishing speed at impact, sight line distances, reaction times, and which party's conduct was the proximate cause of the collision. Their analysis is particularly valuable in disputed-fault cases where both sides have competing narratives about what happened.
Medical Records Establishing Injury Causation
Comparative fault disputes often extend to causation — whether a specific injury was actually caused by this accident or existed beforehand. Detailed and timely medical records establish that your injuries arose from the collision. Emergency room records, imaging studies, and treating physician notes that link your conditions to the accident close off the insurance company's most common causation argument.
Cell Phone Records
When distracted driving is suspected — a driver who appeared to look down at the moment of impact, or who was slow to react to an obvious hazard — cell phone records can confirm whether a call or text was active at the time. Subpoenaing these records requires legal process, but they can be among the most powerful fault evidence available, particularly in rear-end collision cases.
The Role of the Jury vs. the Judge
In a Missouri personal injury trial, the jury — not the judge — apportions fault percentages among the parties. The judge provides legal instructions on the standard of care and the elements of negligence, but the factual determination of who was how much at fault is the jury's responsibility. This means that fault percentages are not fixed — they are argued, contested, and decided by a panel of your peers based on the evidence presented. The stronger your evidence, the more favorable the apportionment is likely to be.
How Comparative Fault Affects Your Settlement Calculation
Understanding the math behind comparative fault helps you evaluate whether a settlement offer is fair — and recognize when an insurance company is manipulating your percentage to underpay you.
The calculation is straightforward: your total proven damages are multiplied by the percentage of fault assigned to the other party. If a jury finds your total damages to be $200,000 and assigns you 25% of the fault, your recovery is reduced by $50,000 (25% of $200,000), leaving you with $150,000. The 75% attributed to the other party is what you collect.
The math matters — run the numbers before you settle
Example A: $200,000 in damages — 25% your fault → you recover $150,000.
Example B: $300,000 in damages — 50% your fault → you recover $150,000.
Example C: $500,000 in damages — 40% your fault → you recover $300,000.
Even with significant shared fault, substantial recoveries are possible. The insurance company's goal is to inflate your fault percentage, shrink your damages estimate, and get you to accept less than the formula supports.
Insurance adjusters understand comparative fault law better than most injury victims do. They use that knowledge strategically. In early settlement communications, adjusters will often state — with apparent authority — that you were 40%, 50%, or 60% at fault, and frame a low settlement offer as a "generous" reflection of your "limited" recovery rights. These fault assessments are not determinations of fact. They are opening negotiating positions designed to anchor your expectations at a level that protects the insurer's bottom line.
The adjuster's fault percentage is not binding. It is not a court ruling. It is the insurer's self-interested characterization of the evidence, offered before a full investigation has been completed. An attorney who conducts an independent investigation, preserves evidence, and presents the strongest version of your case can substantially shift that number — and with it, your recovery.
Common Situations Where Comparative Fault Applies
Comparative fault arises in nearly every category of personal injury case. Recognizing how it applies in your specific situation helps you understand what evidence is most important to gather and preserve.
Car Accidents
Car accident cases are the most common arena for comparative fault disputes. The classic scenario involves two drivers who each contributed to a collision — one was speeding, the other ran a yellow light. But comparative fault also arises when one driver was texting while the other failed to yield, or when a rear-end collision involves a driver who stopped suddenly and a following driver who was traveling too closely. Both drivers can be partially at fault, and both can recover from the other. The Missouri Supreme Court has been clear that apportionment applies even in multi-vehicle accidents where fault is distributed among several parties.
Pedestrian Accidents
Pedestrians involved in vehicle collisions are frequently assigned some comparative fault, particularly if they crossed outside a designated crosswalk, crossed against the signal, or stepped into traffic from between parked vehicles. However, even a pedestrian found 40% at fault recovers 60% of their damages under Missouri law. And drivers bear a heightened duty of care toward pedestrians — Missouri law requires drivers to exercise the highest degree of care, a standard that is often more demanding than pedestrians appreciate.
Truck Accidents
In collisions involving commercial trucks, the injured motorist may be assigned partial fault for failure to yield when entering a highway, an improper lane change near a commercial vehicle, or traveling in a truck's documented blind spot. These arguments are commonly raised by trucking company insurers because large verdicts are at stake and even modest fault-percentage shifts translate to significant dollar reductions. Evidence of FMCSA violations by the truck driver — hours-of-service violations, defective brakes, logbook falsification — often significantly outweighs any comparative fault attributed to the other motorist.
Slip and Fall Accidents
Premises liability cases involving slip and falls frequently generate comparative fault arguments. A property owner may claim that the injured person was not watching where they were walking, was wearing inappropriate footwear, or ignored visible warning signs. Missouri courts weigh this against the property owner's duty to maintain safe conditions and provide adequate warning of known hazards. When a hazard is not obvious or the warning was inadequate, the property owner's fault typically predominates — but the injured person's conduct remains part of the analysis.
Workplace Injuries
In Missouri personal injury claims arising from workplace accidents not covered by workers' compensation — or where a third party (not the employer) caused the injury — comparative fault applies. A worker who did not use available personal protective equipment, or who operated machinery in a manner contrary to training, may be assigned partial fault. But if the equipment itself was defective or the worksite was unreasonably dangerous, the manufacturer's or property owner's liability typically remains substantial.
Why You Need an Attorney Even If You Think You Were Partly at Fault
The single most important thing to understand about comparative fault is this: you do not determine your fault percentage — and neither does the insurance adjuster. Your percentage is determined through investigation, negotiation, and if necessary, a jury. An attorney's job is to contest every unfair assignment of fault, build the evidence record that supports the most favorable apportionment, and ensure that the other party's negligence is fully documented and quantified.
Consider what is at stake. If your case involves $300,000 in total damages — medical bills, lost wages, pain and suffering — the difference between being found 50% at fault and 20% at fault is $90,000. The difference between being found 60% at fault and 30% at fault is also $90,000. These are not small numbers, and they are directly shaped by the quality of the investigation and advocacy behind your claim.
Insurance companies have claims professionals, defense attorneys, and accident reconstruction experts working to maximize your assigned fault percentage the moment a claim is filed. They have the resources, the experience, and the financial incentive to do this aggressively. Going into that process without legal representation means ceding the investigative and advocacy advantages to the party that benefits most from assigning you maximum blame.
An experienced Missouri personal injury attorney does things that are simply not available to unrepresented claimants. They send spoliation letters to preserve black box data, surveillance footage, and maintenance records before they are lost. They retain expert witnesses who can reconstruct the accident and testify to the other party's negligence. They depose drivers, witnesses, and corporate representatives. They review the full medical record and retain medical experts to establish causation and project future treatment costs. They know when a settlement offer is inadequate and are prepared to go to trial if the insurer will not pay fair value.
Even at 50% fault, recovery on a $300,000 case is $150,000 — money that pays medical bills, covers lost income, and compensates you for the physical and emotional toll of a serious injury. That is $150,000 you would not collect if you accepted the insurance company's narrative that your partial fault means no case.
