Understanding Missouri Comparative Fault in Car Accident Claims: A Simple Guide

Quick Summary
Missouri uses a “comparative fault” system in car accident cases. That means even if you were partially at fault, you can still recover money for your injuries—your compensation is simply reduced by your percentage of responsibility. This rule matters because insurance companies often use it to argue you deserve less than your full claim value.
At Mook Law Firm LLC in Kansas City, Missouri, I help injured persons navigate comparative fault arguments every day. Knowing how the system works can make a big difference in the outcome of your claim.
What Is Comparative Fault in Missouri?
Missouri follows a “pure comparative fault” rule. In plain English: each driver is assigned a percentage of fault, and your recovery is reduced by that percentage—but never eliminated unless you are 100% at fault.
For example:
- If you’re awarded $100,000 but found 20% at fault, you still recover $80,000.
- If you’re 60% at fault, you can still recover 40% of your damages.
This is different from states that completely bar recovery once you’re over a certain fault threshold. Missouri gives injured people more opportunity to recover—even when an insurance company tries to shift blame.
Examples of Shared Fault in Missouri Car Crashes
1. Unsafe Lane Change
Driver A merges without checking blind spots. Driver B is speeding. Both drivers share blame. Driver A may be 70% at fault for the unsafe lane change, while Driver B may hold 30% for speeding.
2. Following Too Closely
Rear-end collisions may involve shared responsibility. Driver A brakes suddenly. Driver B was following too closely. Even though B hit A, fault may be divided.
3. Failing to Avoid an Accident
Driver A swerves into the wrong lane and hits Driver B. Driver B’s insurer may argue that Driver A should have seen Driver B swerving and avoided the wreck as a strategy to avoid payment.
These examples show why comparative fault can be complicated—and why having an experienced Missouri personal injury attorney matters.
How Comparative Fault Can Reduce Your Recovery
Insurance adjusters know the comparative fault rule well, and they commonly use it to argue for lower payouts—for example:
- Claiming you were speeding when hit by another driver
- Arguing you “should have reacted sooner”
- Saying both drivers share blame even when evidence disagrees
