How Truck Accident Claims Work

Under the law, those who sustain personal injuries caused by the negligence of a person or entity can pursue full compensation for their damages. The path to justice and accountability, however, is not always a simple one. Trucking companies and their insurers will often go to great lengths to minimize their legal liability after an accident. This leaves the victim in danger of having to pay medical bills, incur lost wages, and suffer other out of pocket expenses.

Hiring a local Ontario truck accident lawyer and filing a legal claim may be necessary to avoid this and to hold the negligent party accountable. To successfully prove your civil claim for negligence, you will need to show:

  • The other party owed you a duty of care, such as driving with care or making sure their truck drivers are qualified.
  • The other party breached the duty of care through an act of negligence, which means they failed to meet the standard of care. An example would be if a truck driver drove while under the influence or was distracted by looking down at their phone.
  • You suffered injuries and damages as a result of that negligence, whether they were minor, life-changing, or anything in between.

Who Is at Fault for a Truck Accident?

One or more of the following parties may be considered at fault for a preventable truck accident:

  • Truck driver: Drunk driving, distracted driving, speeding, and other types of reckless/negligent driving on the part of a truck driver can lead to a crash. But while their actions may have directly or indirectly caused a crash, truck drivers are rarely the sole defendant named in a truck accident lawsuit.
  • Trucking company: In most cases, a trucking company is said to be responsible for the negligence of any employees, including truck drivers, loaders, and others. That means if the truck driver or another employee caused the accident, the trucking company will l be named as a defendant.
  • Third-parties: This may include the owner(s) of the trailer, independent cargo loaders, mechanics, managers, or brokers, among others. Common examples include when a cargo loader fails to balance a truck’s cargo properly, when an in-house mechanic fails to maintain a truck, and when a manager orders a truck to be overloaded with cargo.
  • Truck parts manufacturer: In the event that a truck crash was caused by brake failure, a tire blowout, or another technical malfunction, the parts manufacturer may be considered at fault.
  • Other motorists: A driver of a motor vehicle, motorcycle rider, or others may have been reckless or negligent.

Wisner Baum’s Ontario truck accident attorneys will dig deep into the details of your case to understand who is at fault. Then, we will work to prove liability. No matter the circumstances, no matter the complexity of the case, we will work tirelessly to secure the best possible result for you and your family.

How a Truck Accident Lawyer Can Help You With Your Case

One of the most common questions people ask after a truck accident is why their case needs a lawyer. An experienced truck accident lawyer with a proven track record will help ensure that your claim goes as smoothly as possible. In addition to maximizing your compensation, we will also work to effect real change to prevent your tragedy from happening to others.

The benefits of working with an Ontario truck accident lawyer include but are not limited to:

  • Compassionate legal counsel that goes beyond lawyering: After a crash, you need honest, compassionate counsel to guide you through the process of making a claim. This is especially true since the legal process can seem overwhelming and complicated. Our lawyers have handled legal claims from start to finish for nearly 50 years. From your free consultation until your case is resolved, we stop at nothing to get you the results you deserve so you can focus on what’s most important: your health.
  • Someone to take care of the day-to-day legal work: If you decide to take legal action, we can handle all the paperwork and make sure it is submitted correctly and before the statute of limitations runs. We can also handle every facet of your claim, from investigation and discovery to settlement talks, to representing you in court.
  • Strengthen your case with facts and evidence: We will leave no stone unturned while investigating your case. This allows us to build a strong, viable claim. We will also make sure it is trial-ready. Often, this will incentivize the at-fault party to offer a fair settlement before trial begins. If they try to shortchange you, we will fight to get you full compensation through a jury verdict.
  • Improve your chances of winning your claim: An Insurance Research Council study found that the average person receives a settlement 3.5-times larger when they retain an attorney to represent their interests when compared to those that go it alone without an attorney.
