What Is a Personal Injury Lawsuit?

A personal injury lawsuit is a type of civil dispute stemming from an accident in which one person sustained harm and another person or entity (business, corporation, or government agency) may be legally responsible. An attorney prepares and files a personal injury lawsuit on behalf of the victim (the plaintiff) in pursuit of compensation for the victim’s injuries otherwise known as damages. The lawsuit alleges that a defendant’s carelessness or negligence caused harm to the plaintiff (the injured victim).

The plaintiff carries the burden of proving that the defendant was negligent. Since these lawsuits are handled in the civil justice system (not the criminal justice system), the plaintiff will only need to show that the defendant was more likely than not negligent. They will not have to prove their case “beyond a reasonable doubt.”

Most personal injury lawsuits result in a settlement out of court. Settlements are negotiated between the plaintiff’s attorney and the defendant’s insurance company and legal counsel.

Winning Your Personal Injury Case

There are a few key points you will need to prove to win a personal injury claim.

The first is that someone else owed you a duty. This means different things in different cases. For example, a product manufacturer has a duty to ensure any product they put to market is safe for consumers or warn of any potential side effects, etc. AS another example, a trucking company has a duty to ensure its truck drivers are qualified and properly trained to drive large commercial vehicles safely.

Second, the lawyer must prove that the defendant breached the duty of care. Again, this will look different for every case. A few examples include distracted driving, cutting corners during the manufacturing process, failing to warn of the potential for toxic exposure, etc. Whatever the negligence is, your personal injury attorney will need to prove it was committed.

Your lawyer will also need to prove that the negligence caused your injury, hence your claims for damages. If your attorney is successful, the injured victim will be compensated for damages according to proof.

To prove negligence, there are 4 parts: duty, breach, causation, and damages.

  • Duty: Does the defendant owe the plaintiff a duty of care? In auto cases, including trucking, the defendant owes a duty of care to operate their vehicle as a reasonable driver/trucker would. That also includes maintaining, inspecting, etc., the vehicle. Trucking companies owe a duty to ensure that employees are properly trained, have a clean driving history, do have dangerous medical conditions, etc.
  • Breach: Did the defendant breach the duty of care. In other words, did the defendant fail to operate, inspect, maintain, the vehicle in a reasonable manner. If their actions fell below the standard of care (reasonableness, usually), then there is a breach.
  • Causation: Are the injuries that the plaintiff suffered the result of the negligent conduct. This is usually pretty clear, but sometimes there are times when another person’s negligence will intervene.
  • Damages: Did the plaintiff suffer legally recognized damages, which include economic damages, such as lost wages and medical expenses, and physical injuries and pain and suffering (Economic and non-economic damages.)

Compensation Available to Personal Injury Victims

A personal injury lawsuit may result in compensation for economic (financial) and non-economic (emotional and mental) damages.

Economic damages include:

  • Hospital stays
  • Doctor’s visits
  • Prescription medication
  • Assistive devices
  • In-home accommodations
  • Caregiver compensation
  • Surgeries
  • Physical, occupational, and other therapies
  • Lost wages
  • Lost benefits
  • Loss of earning capacity
  • Reduced future earning potential

Non-economic damages, on the other hand, are those that do not come with a bill. Some examples include:

  • Pain and suffering
  • Emotional distress
  • Loss of quality of life
  • Loss of enjoyment of life
  • Disability, scarring, and disfigurement

If the person or entity’s actions were with reckless disregard for your safety or the safety of others, or was malicious, you may be awarded punitive damages which are higher than the initial award and meant to punish the defendant. The amount of total compensation for a personal injury lawsuit can potentially be in the millions.
