Being involved in an accident can be a traumatic experience and may lead to a lengthy legal process when seeking compensation. If you are found to also have contributed to the accident or severity of your injuries, the process can seem even more daunting and overwhelming.

If you’ve been involved in an accident and are found to have contributed to the incident or the severity of your injuries, it’s important to have an experienced legal advocate in your corner. A lawyer who understands contributory negligence law can help you navigate your claim, protect your rights, and pursue the compensation you may be entitled to.

Defining Contributory Negligence

Contributory negligence is a legal principle that may apply in claims where an injured person is found in some way to have contributed to the accident or severity of their resulting injuries. In a personal injury claim, the defendant may argue that the injured person failed to take reasonable care for their own safety or otherwise contributed to the circumstances that caused their injuries to occur. If the court finds that you were partially responsible, or you are found to have contributory negligence, your compensation may be negatively impacted or reduced to reflect your share of the responsibility.

Contributory negligence could arise in instances where someone::

  • Was not following the appropriate safety rules or instructions for the situation;
  • Failed to use due care to avoid obvious danger;
  • Was distracted at the time of the accident;
  • Fail to follow medical advice after an injury, potentially prolonging or worsening the condition;
  • Was not wearing appropriate safety equipment for the situation.

Compensation Impacts

In personal injury cases where more than one person is found to have contributed to an accident through negligent action, the court may split responsibility between the parties involved, based on their respective levels of negligence towards the resulting situation, accident, and injuries. The amount of compensation awarded to an injured person can, as a result, be reduced to reflect their share of responsibility in what occurred.

As an example, imagine that two drivers are involved in a car accident. Driver A was speeding and crossed paths with Driver B, who was entering an intersection against a red traffic light. If the speeding driver (Driver A) is injured, they may still be entitled to compensation, even though their actions directly contributed to the severity of the resulting accident.

However, the court may determine that both drivers were negligent in their actions, and assign a percentage of fault to both Driver A and Driver B. If the injured Driver A is found to be 40% at fault, while Driver B is found to be 60% at fault, then Driver A’s compensation may be reduced by 40% to reflect their contributory negligence and their share of responsibility for what resulted.

The exact amount of compensation that the injured driver may ultimately be awarded will depend on the specific circumstances of the accident, the evidence available, and how responsibility is ultimately divided. Determining fault in an accident isn’t always straightward, which is why it can be largely beneficial to have experienced legal counsel in claims where contributory negligence has been raised.

How is Contributory Negligence Proven?

To establish contributory negligence, the exact circumstances of the accident, including the moments leading up to it, will be thoroughly reviewed. Generally, there are three considerations involved in establishing contributory negligence:

The plaintiff owed themselves a duty to take reasonable care:

The injured person is expected to take reasonable steps to protect themselves from foreseeable harm or immediate danger where possible. This does not mean that they are required to anticipate possible danger, instead that they should be acting with appropriate levels of care in the given circumstances.

The plaintiff failed to act as a reasonable person would have:

The injured person acted, or failed to act, in a way that fell below the standard of reasonable care. This may include ignoring known risks, failing to follow safety instructions, or otherwise behaving in a manner that a reasonable person would not have under similar circumstances, to avoid injury.

The plaintiff’s conduct contributed to the accident or injuries:

There must be a verifiable connection between the plaintiff’s actions and the injuries that they ultimately suffered, or to the worsening of those injuries.

It’s important to remember that being found as having contributory negligent actions in a claim, it does not prevent you from pursuing any type of personal injury claim. Instead, depending on the applicable law and the circumstances of the case, the court may assign a percentage of responsibility to all of the parties involved, and adjust the appropriate damages accordingly.

Because contributory negligence will ultimately depend on the specific circumstances involved in an accident, determining whether an injured party shares partial responsibility can ultimately be complex. An experienced personal injury lawyer can review the circumstances surrounding your car accident, assess the available evidence, and help to determine how the allegation of contributory negligence may affect the resulting claim, possible damages.

What Happens When More Than Two People are Liable for an Accident?

The situation can become more complicated when more than two parties are found to be responsible for, or have contributed to an accident. When an accident causes an injury, and multiple parties involved are found to have acted with negligence, the court may assign each person a percentage of fault based on their role in causing the accident or injuries.

For example, if three people are found to have contributed to an accident, the court may determine that each person was responsible for a different percentage of the negligence. If the injured person is also found to have contributed to the accident, their compensation may ultimately be reduced to reflect their share of fault.

These cases can involve complex questions about who was responsible, how much each person contributed to the resulting events, and how the injured person’s damages should be calculated. Having an experienced personal injury lawyer can help you to understand your rights and ensure that your share of possible responsibility is properly assessed.

The “But For” Test

The “but for” test is a method used by the courts to help determine whether a person’s actions or failure to act contributed to an injury. Put simply, the question is: “But for this person’s actions, would the accident or injury have happened?”

For example, imagine Driver A was speeding and Driver B ran a red light. If Driver A had been travelling at a safe speed, could they have stopped in time to avoid the collision? If the answer is yes, Driver A’s speeding may have contributed to the accident.

The “but for” test is used in some situations by the court to help determine whether a person’s conduct was connected to the injury. In contributory negligence cases, this may help to establish whether the injured person’s own actions played a role in causing the accident or making their injuries worse.

Courts must take a practical approach when considering contributory negligence and whether the plaintiff has proven their case. While scientific or expert evidence can be helpful, it is not always required to establish how an accident occurred, or whether a person’s actions contributed to their injuries.

The “but for” test can also be difficult to apply because both sides may have different vows about what would have happened if a person had acted differently. The court must consider the available evidence and the circumstances as a whole when deciding whether a person’s actions contributed to the accident or their injuries.

Because these case arguments can have a direct impact on the amount of compensation an injured person receives, having an experienced personal injury lawyer can be extremely valuable. Our lawyers can assess the available evidence, respond to arguments about contributory negligence, and help present a clear case about what caused the accident and resulting injuries.

What May Be Considered Contributory Negligence?

There are numerous situations where contributory negligence may be raised in an accident claim. Generally, it may apply when a person fails to take reasonable care for their own safety and that failure contributes to an accident, or ultimately worsens their own injuries.

The specific circumstances of each unique case matter. Actions that may be considered negligence in one situation may not be viewed the same way in another, and environmental factors need to be considered. Some examples that may raise questions of contributory negligence by a defendant include:

  • Cyclists and motorcyclists who do not wear a helmet, where a helmet could have helped to prevent or reduce the severity of an injury.
  • Pedestrians who cross outside a designated crosswalk, or use their phones in a way that distracts them when they are crossing the street.
  • Failing to yield the right of way when required.
  • Entering private property or clearly marked restricted areas without permission.
  • Pedestrians wearing dark clothing at night without reflective materials, particularly where visibility is an important factor in the accident.
  • Drivers or passengers who fail to wear a seatbelt, while doing so may have reduced the severity of their injuries.
  • Failing to seek medical attention after an accident. Even if you initially feel fine, some injuries may not present until hours or days after an accident. If a person delays medical treatment longer than necessary and their condition becomes worse as a result, the delay could potentially be raised as contributory negligence.

It’s important to remember that not every unsafe action will automatically amount to contributory negligence. The court will consider the facts of the case, the person’s conduct leading up to and after the accident, and whether the conduct actually contributed to the accident or the severity of the injuries. If contributory negligence is being raised in your personal injury claim, an experienced personal injury lawyer can help determine how this may impact your case and potential compensation.

Proving Contributory Negligence

Evidence is an important part of determining whether someone contributed to an accident or the severity of their own injuries. If you have been involved in an accident, reporting it to the police or the appropriate authority can create an official record of what happened. This report may later be useful when determining how the accident occurred and who may have been responsible.

It may be beneficial to collect the names and contact information of anyone who witnessed the accident, and moments leading up to the incident. Witness statements from unbiased third parties can provide an independent account of what happened and may help confirm important details.

Photos and videos can also be incredibly valuable evidence for a claim. Be sure to take photographs of the accident scene, any visible hazards, vehicle damage, and your injuries when it is safe for you to do so. If the accident happened near a business, a home, parking lot, or other location with security cameras available, the footage may also provide important evidence. Because security footage is often deleted after a certain period, it is important to identify potential sources of video as soon as possible.

Medical records, accident reports, photographs, witness statements, and other documents may all help to establish the events leading up to the accident, and whether anyone involved contributed to the accident and resulting injuries.

I’ve Been Injured in an Accident, But May be Partially at Fault

If you’ve been injured in an accident, seek medical attention as soon as possible, even if your symptoms seem minor or you do not feel injured right away. Some injuries may not be immediately obvious, and symptoms can develop hours or days after an accident occurred. By receiving prompt medical care, you can help to identify injuries, support your recovery, and create a record of your condition.

Be sure to document what happened while the details are fresh in your mind. Keep copies of all medical records, photographs, accident reports, insurance correspondence, and other documents related to the incident. Avoid making statements that could be misunderstood as accepting responsibility before you have had the opportunity to understand your legal rights.
