What Is Comparative Negligence?

Comparative negligence is a legal principle that determines the compensation that may be recovered if an injury victim is partially at fault. Multiple parties may be liable for a truck accident. Sometimes, this may include the driver who sues for damages.

Understanding Ohio’s Modified Comparative Negligence Rule

Ohio law uses a modified comparative negligence standard. Also known as the 51% rule, it allows you to recover damages as long as your share of responsibility is less than that of the defendant(s).

The modified comparative negligence rule can be found in Ohio Revised Code § 2315.33. In addition to explaining how comparative fault works in Ohio truck accident cases, an experienced attorney can provide you with practical advice for making a claim and anticipating potential defense strategies. This includes allegations that you were responsible for the accident.

How Does Modified Comparative Negligence Work?

Comparative negligence is calculated in terms of percentages, with 100% representing the total level of fault for the accident. If you are 50% or less at fault, you can still recover damages. However, the damages are reduced according to your percentage of responsibility.

For example:

• If you are 10% at fault, you would be entitled to 90% of your losses.
• If you are 20% at fault, you would be entitled to 80% of your damages.
• If you are 25% at fault, you would be entitled to 75% of any losses.
• If you are 30% at fault, you would be entitled to 70% of any damages.
• If you are 40% at fault, you would be entitled to 60% of your losses.
• If you are 50% at fault, your damages are cut in half.

And, if your share of fault is calculated at 51% or higher, you would not be entitled to any damages at all.

Comparative Negligence Truck Accident in Ohio: An Example

Say you are traveling along I-270 in the right lane. There’s an 18-wheeler ahead of you, and you move over a lane to pass it. Suddenly, the truck veers into the middle lane and smashes into your vehicle. You are seriously injured in the crash, while the truck driver is unscathed.

Your damages from the accident are calculated at $100,000. Investigation of the wreck reveals that the truck driver failed to check his blind spots before changing lanes. The investigation also shows that you were exceeding the speed limit when passing the big rig.

Ultimately, the truck driver is assigned 90% of the fault while you are found to be 10% at fault. The comparative negligence rule allows you to pursue damages, but your compensation cannot exceed $90,000.

Why Comparative Negligence Is Important in Truck Accident Claims

Semi-truck accidents are often serious, especially for victims in passenger vehicles. If you sustain a catastrophic injury that will affect you the rest of your life, it is worth determining if someone else was to blame.

Often, there is more than one defendant in a trucking accident claim:

• The driver of the semi-truck for distracted driving, unsafe lane changes, etc.
• A trucking company for failure to hire qualified drivers, follow safety regulations, etc.
• Parts manufacturers for brake failures, tire blowouts, and other defects
• Cargo loaders for overloading the truck or failing to secure cargo
• Mechanics who fail to inspect and repair the truck

Identifying each of these parties is essential for obtaining maximum compensation in your case. You also need to be prepared for one or more defendants to point the finger at you. Insurers will seize on a comparative negligence truck accident in Ohio because it gives them a reason to pay less (or nothing at all).

Driving too fast, not signaling a turn, and other behaviors may contribute to the accident and make you partially at fault. However, the insurance company should not lay the blame entirely on you if the negligence of others was more of a contributing factor.

What Evidence Can Determine Fault?

Truck accident claims require strong evidence. Evidence that can be used to establish who was at fault for the crash includes:

• Photographs of the accident scene
• Eyewitness recollections
• The police crash report
• Video footage of the accident
• Data from the truck’s black box
• Cell phone data and GPS records
• Testimony from expert witnesses

Ultimately, the evidence needs to prove that one or more parties’ negligence led to the truck crash. This often involves showing that truck drivers and trucking companies violated federal regulations. Proving that a defendant violated a regulation (such as the hours of service rules) can help shift responsibility for the accident.

Who Is Responsible for Determining Fault?

Multiple parties may be involved in determining fault over the course of your claim. The crash report may contain the investigating officer’s observations and opinion on what caused the truck accident, but these are not definitive conclusions.

Fault determinations generally fall to these parties:

• Insurance adjusters: The insurance company will decide whether it is obliged to accept liability and what they are willing to pay. Usually, this will be less than your case is truly worth.
• The Court: If your case proceeds to trial, the local Court of Common Pleas will make the ultimate decision regarding fault. A judge or jury will examine issues of comparative negligence and determine what percentage of fault is attributable to each party.

You need an experienced attorney to represent you in settlement negotiations. Legal representation is also essential for filing a truck accident lawsuit and making an effective case at trial. Knowledgeable lawyers can answer questions about a comparative negligence truck accident in Ohio and advocate for the best result on your behalf.

What to Do If You’re Being Blamed for a Truck Accident

It’s awful enough to be hurt by a semi-truck. Hearing others blame you for the crash literally adds insult to injury, especially when you know you weren’t in the wrong. Unfortunately, losing your cool can prove costly. Remain calm, and take the following steps:

1. Never say “I’m sorry” — not to the truck driver, not to the insurance adjuster, not to anyone involved.
2. Keep all medical appointments so your injuries are fully documented.
3. Don’t give a recorded statement to any insurance company.
4. Stay off of social media and avoid posting about the accident.
5. Consult a Columbus 18-wheeler accident lawyer ASAP.

These do’s and don’ts can make a big difference in your case. Insurance companies love to look for loopholes, and they will jump at any chance to say you were at fault. By not giving them the opportunity to blame you, you reduce the likelihood of a dispute and improve your chances for a favorable outcome.

What Damages Can I Recover for a Comparative Negligence Truck Accident in Ohio?

Negligence on your part may reduce the amount of damages you can recover, but it doesn’t change the compensation that may be available if an 18-wheeler hits you. If you are less than 51% responsible for the wreck, you may still be entitled to:

• Medical expenses, including the cost of ambulance transport, hospital care, surgeries, etc.
• Future medical bills for therapy, rehabilitation, and ongoing treatment needs
• Lost wages to date
• The loss of earning capacity in the future
• Out-of-pocket costs (medical equipment, household services, etc.)
• Pain and suffering for the physical and emotional toll of your injuries
• Mental anguish, if you suffer psychological trauma as a result of the truck accident
• Loss of enjoyment of life, if your injuries negatively impact your day-to-day life, relationships with your family, and ability to partake in favorite activities

You may even be able to obtain punitive damages if the case goes to trial. These damages are rarely awarded by Ohio courts, but they may be available if there is evidence of malice on the part of a defendant. A finding of comparative negligence would reduce a punitive damages award, with the 51% threshold still applying to the two-stage trial process described in Ohio Revised Code § 2315.21.

Don’t let the defendants try to avoid fault or the insurance company to avoid paying what you’re due. Comparative negligence isn’t always cut-and-dried, and a skilled attorney may be able to prove that you are entitled to full compensation for your injuries and damages.
