Missouri crash claims fall under pure comparative fault, allowing recovery at any fault level. The fight centers on where the fault line is drawn — and physical evidence from the crash scene is what draws it.
How Pure Comparative Fault Shapes Your Crash Claim
Under Missouri's pure comparative fault system, your crash claim cannot be eliminated by a fault finding — no matter how high the percentage. A claimant at 90 percent fault still recovers 10 percent of the total damages. The system operates on a sliding scale rather than a pass-fail threshold.
The strategic implication is that every disputed percentage point carries a dollar value. The insurer's goal is not to bar your claim but to inflate your fault share as high as possible, shrinking your recovery proportionally. Your goal is the opposite: use crash-scene evidence to push your assigned fault as low as the facts support. The evidence battle in a pure comparative state is about the size of the check, not its existence.
Reducing Your Fault Share Through Crash Evidence
Fighting fault allocation in a pure comparative state means building an evidence case that the insurer cannot ignore. The insurer's initial fault estimate is designed to maximize their savings — not to reflect the facts accurately. Your task is to present evidence compelling enough to force a lower number.
The most effective crash evidence is objective and contemporaneous. Photographs taken at the scene before cleanup, event data recorder output from the seconds before impact, and unedited surveillance footage carry more weight than statements made days or weeks later. Witness accounts are strongest when recorded promptly with full contact details. A formal spoliation letter preserving the other vehicle's electronic data should be sent immediately — once that data is gone, it cannot be reconstructed.
A worked example with Missouri’s rule applied
Take a crash claim with documented losses like these:
| Medical bills | $21,500 |
| Lost wages | $3,400 |
| Other out-of-pocket costs | $2,400 |
| Pain and suffering (2.5× medical) | $53,750 |
| Gross value before fault | $81,050 |
Now apply Missouri’s pure comparative rule. Say the insurer pins 30% of the fault on you: the claim is reduced by $24,315 to $56,735 — but it survives. Even a driver found 30% at fault still recovers the remaining share here, which is exactly why adjusters in pure-comparative states argue percentages rather than trying to kill the claim outright.
Building the Crash Evidence File in Missouri
Fault in a crash claim is decided by evidence, not assumptions. The evidence chain starts at the scene: time-stamped photographs of vehicle positions, damage patterns, road conditions, and traffic signals. Dashcam footage — yours or from nearby vehicles — preserves the collision sequence before accounts diverge or memories fade.
Electronic vehicle data adds objectivity. Event data recorders in modern vehicles log speed, brake pressure, and steering angle in the seconds before impact. This data is factual — it does not depend on credibility or recollection. Preserving it requires a spoliation letter sent promptly to the other driver and their insurer, putting them on formal notice that destroying evidence will carry legal consequences. Act within hours, not days.

Questions
Missouri questions
Does shared fault destroy my crash claim in Missouri?
No. Missouri follows pure comparative fault, meaning your claim survives at any fault level. Your recovery is reduced by your assigned fault percentage — 30 percent fault means 70 percent of total damages. The dispute is always about the size of your fault share, and evidence is what determines that number.
How is the fault percentage determined in a Missouri crash case?
Fault percentage is built from crash-scene evidence: police reports, photographs, vehicle data recorder output, witness statements, and sometimes expert reconstruction. The insurer proposes a number, but that number is not final. Stronger documentation gives you leverage to challenge the assessment and push the assigned percentage lower.
If I am mostly at fault for a crash in Missouri, can I still recover damages?
Yes. Pure comparative fault allows recovery at any fault percentage. A claimant at 80 percent fault can collect 20 percent of total damages. The insurer will attempt to assign the highest percentage possible, so your crash-scene evidence is the primary tool for limiting that number and increasing your recovery.
