How Missouri’s Comparative Fault System Affects Your Car Accident Claim
Proving fault in a Missouri car accident can mean the difference between receiving full compensation and getting nothing at all. Unlike some states, Missouri follows a “pure comparative fault” system that allows you to recover damages even if you’re partially responsible for the accident. However, understanding how to establish fault and gather compelling evidence is crucial to maximizing your recovery.
At The Dixon Injury Firm, Christopher R. Dixon has successfully proven fault in hundreds of St. Louis car accident cases, recovering over $60 million for clients. Our comprehensive approach to fault determination combines legal expertise with thorough investigation to build unshakeable cases.

Understanding Missouri’s Comparative Fault Law
Pure Comparative Fault Explained
Missouri Revised Statutes § 537.765 establishes pure comparative fault, meaning your compensation is reduced by your percentage of fault, but you’re never completely barred from recovery.
How It Works:
- 0% fault: Recover 100% of damages
- 20% fault: Recover 80% of damages
- 50% fault: Recover 50% of damages
- 80% fault: Recover 20% of damages
- 99% fault: Still recover 1% of damages
Real Case Example:
Client was 30% at fault for turning left without yielding but other driver was 70% at fault for speeding and texting. Total damages: $150,000. Client recovered: $105,000 (70% of total).
Why Fault Determination Matters
Financial Impact:
- Every 1% of fault costs you 1% of your compensation
- In major injury cases, each percentage point can mean thousands of dollars
- Insurance companies aggressively argue for higher fault percentages against you
- Proper fault investigation can shift liability dramatically
Strategic Considerations:
- Early fault determination shapes entire case strategy
- Evidence preservation becomes critical immediately after accident
- Witness testimony can make or break fault arguments
- Expert reconstruction may be necessary for complex cases

Common Fault Scenarios in St. Louis Car Accidents
Rear-End Collisions
Presumption of Fault: Missouri law presumes the following driver is at fault in rear-end collisions, but this presumption can be overcome.
When Following Driver Is at Fault:
- Following too closely: Violating safe following distance
- Distracted driving: Texting, eating, or other distractions
- Speeding: Excessive speed preventing safe stopping
- Failure to maintain lookout: Not paying attention to traffic
When Lead Driver May Share Fault:
- Sudden stops: Stopping without warning for non-emergency
- Broken brake lights: Failure to signal stopping intention
- Improper lane changes: Cutting off following vehicle
- Mechanical failures: Ignored maintenance causing sudden stops
Case Study: Client rear-ended another vehicle but investigation revealed lead driver brake-checked our client after road rage incident. We proved 70% fault against lead driver, recovering $180,000 of $250,000 in total damages.
Intersection Accidents
Right-of-Way Violations: Intersection accidents often involve disputes over traffic signal compliance.
Proving Signal Violations:
- Traffic engineering analysis: Signal timing and phase duration
- Witness testimony: Independent observers of light colors
- Damage analysis: Impact patterns consistent with signal violation
- Speed calculations: Physics-based determination of approach speeds
Left Turn Accidents: Left-turning drivers must yield to oncoming traffic, but exceptions exist.
When Left-Turner Is at Fault:
- Failure to yield: Turning across oncoming traffic path
- Misjudging gap: Insufficient time to complete turn safely
- Signal violations: Turning on red or after arrow ends
When Oncoming Driver Shares Fault:
- Excessive speed: Making gap judgment impossible
- Traffic signal violations: Running red light or stop sign
- Distracted driving: Not seeing turning vehicle in time
Lane Change and Merge Accidents
Establishing Fault in Lane Changes
Lane-Changing Driver Typically at Fault:
- Failure to signal: Not indicating lane change intention
- Unsafe movement: Changing lanes when not safe
- Blind spot failures: Not checking mirrors and blind spots
- Cutting off traffic: Insufficient following distance after change
When Other Driver May Share Fault:
- Speed variance: Traveling significantly faster or slower than traffic
- Blocking maneuvers: Intentionally preventing lane changes
- Following too closely: Not allowing safe merging space

Challenging Common Insurance Company Defenses
“Sudden Emergency” Defense
What Insurance Companies Argue: Defendant faced sudden emergency requiring immediate reaction, excusing normal negligence standards.
How We Counter:
- Foreseeable conditions: Weather, traffic, or road conditions driver should have anticipated
- Speed analysis: Whether driver was traveling appropriately for conditions
- Attention evidence: Proof driver wasn’t maintaining proper lookout
- Alternative actions: Other reasonable responses available to driver
Case Example: Insurance company claimed ice caused unavoidable skid. We proved driver was traveling 15 mph over limit for conditions and failed to use winter tires, establishing 80% fault despite icy conditions.
“Phantom Vehicle” Claims
The Defense: Unknown third vehicle caused accident by forcing evasive maneuver.
Our Investigation Approach:
- Debris analysis: Look for evidence of three-vehicle involvement
- Witness development: Canvass for additional observers
- Surveillance review: Check extended time periods for phantom vehicle
- Physics analysis: Whether claimed maneuver matches damage patterns
Pre-Existing Condition Arguments
Insurance Tactic: Argue injuries existed before accident, reducing or eliminating damages.
Our Response Strategy:
- Medical record review: Document pre-accident condition and limitations
- Treating physician testimony: Explain post-accident worsening
- Functional capacity analysis: Compare before and after abilities
- Apportionment arguments: Seek compensation for aggravation even if pre-existing condition exists

Frequently Asked Questions About Proving Fault
Can I still recover money if I was partially at fault for the accident?
Yes. Missouri’s pure comparative fault system allows recovery even if you were 99% at fault. Your compensation is reduced by your fault percentage, but you’re never completely barred from recovery.
How long do I have to investigate fault in my accident?
While Missouri’s statute of limitations gives you five years to file a lawsuit, crucial evidence disappears quickly. Surveillance footage, witness memories, and physical evidence should be preserved immediately.
What if the police report says I was at fault?
Police reports aren’t admissible in court and can be challenged with better evidence. Officers often lack training in accident reconstruction and may make determinations based on incomplete information.
Can fault percentages change during the case?
Absolutely. As investigation develops and more evidence is gathered, fault determinations can shift significantly. We’ve seen cases where initial 100% fault against our client shifted to majority fault against the other party.
Do I need an accident reconstruction expert for my case?
For complex cases involving disputed liability, catastrophic injuries, or significant damage amounts, expert reconstruction is often essential. Simple rear-end collisions may not require expert analysis.
How do you prove the other driver was distracted?
Through cell phone records, witness testimony, admission statements, and sometimes physical evidence like dropped phones or spilled food. Subpoenas may be necessary to obtain electronic records.
What if there were no witnesses to my accident?
Physical evidence, electronic data, and expert analysis can prove fault even without eyewitnesses. Vehicle damage patterns, skid marks, and traffic control device timing provide objective evidence.
Can weather conditions affect fault determination?
Yes, but drivers are expected to adjust their driving for conditions. Fault may be reduced but not eliminated for weather-related accidents if proper precautions weren’t taken.
Don’t let insurance companies determine fault without a fight. Call The Dixon Injury Firm at (314) 208-2808 for expert fault investigation and maximum compensation recovery.
