How Comparative Negligence Works in Missouri Car Accident Cases

Car accidents can leave victims facing medical bills, lost wages, vehicle damage, and long-term pain. In Missouri, determining who is responsible for a crash is not always straightforward. In many cases, more than one driver may share fault for the accident. Missouri uses a legal rule known as comparative negligence to decide how compensation is awarded when multiple parties contributed to a collision.


Understanding how comparative negligence works can help accident victims protect their rights and avoid mistakes that may reduce their financial recovery. At The Khouri Law Firm, we can provide legal assistance to the St. Louis public after a motor vehicle accident.


What Is Comparative Negligence?


Comparative negligence is a legal doctrine used to assign responsibility among parties involved in an accident. Under Missouri law, an injured person can still recover compensation even if they were partially at fault for the crash. However, their compensation is reduced by their percentage of fault.


For example, if a driver suffers $100,000 in damages but is found 20% responsible for the accident, they may still recover $80,000. The remaining 20% is deducted because of their contribution to the collision.


Missouri follows a “pure comparative negligence” system. This means an injured person may recover damages even if they were mostly at fault for the accident.


How Fault Is Determined in Missouri Car Accident Cases


Insurance companies, attorneys, and sometimes courts review evidence to determine how much fault each party shares. Evidence commonly used in these cases includes:


  • Police reports
  • Witness statements
  • Traffic camera footage
  • Vehicle damage analysis
  • Accident reconstruction reports
  • Medical records
  • Cell phone records
  • Photographs from the accident scene


Insurance adjusters often try to shift blame to reduce the amount their company must pay. Because of this, accident victims should be careful when discussing the collision with insurers.


Examples of Comparative Negligence in Action

Comparative negligence can apply in many different accident situations.


Rear-End Collisions

A driver rear-ends another vehicle at a stoplight. However, the front driver’s brake lights were not working. The court may decide the rear driver was 80% responsible while the other driver was 20% responsible.


Speeding and Distracted Driving

One driver is speeding while another runs a red light because they were texting. Both drivers may share fault for the crash.


Failure to Wear a Seatbelt

Missouri law may allow evidence that a victim failed to wear a seatbelt. While this does not cause the accident itself, it may impact claims involving injury severity.


Why Comparative Negligence Matters


Comparative negligence directly affects the amount of compensation available after a car accident. Even a small percentage of fault can significantly reduce a settlement or court award.


Insurance companies know this and often attempt to argue that the injured party was partially responsible. Common allegations include:

  • Driving too fast
  • Failing to signal
  • Distracted driving
  • Following too closely
  • Failing to avoid the accident


Without legal representation, injured drivers may accept unfair blame that reduces their compensation.


Damages Available in Missouri Car Accident Cases

Victims injured in Missouri motor vehicle accidents may be able to recover compensation for:


Medical Expenses

This can include emergency treatment, hospital stays, surgeries, rehabilitation, medications, and future medical care.


Lost Income

Accident victims may seek compensation for missed work and reduced future earning ability.


Property Damage

Vehicle repair or replacement costs may be included in a claim.


Pain and Suffering

Compensation may also address physical pain, emotional distress, and reduced quality of life.


Steps to Take After a Missouri Car Accident

The actions taken immediately after a collision can affect a future injury claim.


Seek Medical Attention

Even injuries that seem minor may become more serious over time. Medical records also help document the connection between the accident and the injuries.


Document the Accident Scene

Take photos of vehicle damage, road conditions, traffic signs, and injuries whenever possible.


Avoid Admitting Fault

Statements made after an accident can later be used against you. Avoid apologizing or speculating about who caused the crash.


Speak With an Attorney

An attorney can help gather evidence, negotiate with insurance companies, and protect your right to compensation.
