Can I Recover Compensation If I Was Not Wearing a Seat Belt in an Arizona Car Accident?

Yes. You may still recover compensation after an Arizona car accident even if you were not wearing a seat belt.

Not wearing a seat belt does not automatically make you responsible for the crash, and it does not automatically eliminate your personal injury claim.

However, Arizona law does allow an insurance company or defendant to raise what is commonly called the seat belt defense. If they can prove that your failure to wear a seat belt caused injuries that otherwise would not have occurred, or made certain injuries significantly worse, your compensation could potentially be reduced.

That distinction is important.

If another driver ran a red light and hit your vehicle, your failure to buckle up did not suddenly cause that driver to run the red light. The other driver may still be responsible for causing the collision.

The real argument may be about something different: How much of your injury was caused by the collision itself, and how much, if any, was made worse because you were not restrained?

Arizona Requires Seat Belt Use in Many Vehicles

Under Arizona Revised Statutes Section 28-909, front-seat occupants of most passenger vehicles manufactured for model year 1972 or later are required to wear an available seat belt while the vehicle is moving.

Drivers are also required to make sure passengers under age 16 are properly restrained.

Arizona currently treats adult seat belt violations as a secondary enforcement matter. In other words, an officer generally cannot stop a driver solely because the driver or front-seat passenger is not wearing a seat belt. There must be reasonable cause to believe another motor vehicle law was also violated.

But the traffic law is only part of the story.

For someone injured in a crash, the more important issue is how Arizona courts treat seat belt nonuse in a personal injury case.

Not Wearing a Seat Belt Usually Does Not Mean You Caused the Accident

This is where people, and sometimes insurance adjusters, confuse two separate issues.

Consider a simple example.

You are traveling through an intersection with the right of way. Another driver turns left directly in front of you. You are unable to avoid the collision.

You were not wearing your seat belt.

The fact that you were unrestrained ordinarily has nothing to do with why the vehicles collided. You did not cause the other driver to make an unsafe turn.

That driver may still be liable for causing the crash.

Arizona’s comparative negligence law also does not automatically prohibit someone from recovering compensation simply because that person shares some degree of fault. A.R.S. Section 12-2505 generally allows damages to be reduced according to a claimant’s relative degree of fault rather than automatically barring the claim.

Seat belt cases add another layer to that analysis.

What Is the Arizona “Seat Belt Defense”?

The Arizona Supreme Court addressed this issue in Law v. Superior Court, a significant Arizona case involving people who were not wearing seat belts and were seriously injured in a crash.

The court recognized that seat belt nonuse may, under certain circumstances, be considered when determining damages.

But that does not mean an insurance company can simply say, “You were not buckled, so we are cutting your settlement.”

The defendant generally has to establish a meaningful connection between the seat belt nonuse and the injuries.

Under the Arizona Supreme Court’s analysis, important questions include whether:

• A usable seat belt was available.
• Failing to use the restraint was unreasonable under the circumstances.
• The person was of an age and capacity where the nonuse could reasonably be considered fault.
• The lack of a seat belt caused an injury that probably would not have occurred otherwise or made an injury more severe.
• There is evidence establishing with reasonable probability how the lack of restraint affected the injuries.

You can read the Arizona Supreme Court’s decision in Law v. Superior Court.

The practical takeaway is significant: the insurance company should have to prove more than the simple fact that you were not wearing a seat belt.

The Insurance Company Still Has to Connect the Seat Belt to Your Injuries

This may become the most important part of the claim.

Imagine you suffer a broken wrist because your hand strikes the dashboard during a collision. You also suffer a knee injury when the vehicle’s interior collapses inward.

An insurer might argue that wearing a seat belt would have prevented some or all of those injuries.

But is that actually true?

That question may require analysis of the collision, your seating position, the direction and severity of impact, vehicle deformation, medical findings, and how your body moved inside the vehicle.

It may also require expert testimony in a serious case.

Insurance companies sometimes treat an unbelted occupant as if every injury automatically resulted from the missing seat belt. Arizona law requires a more careful analysis.

This is similar to another argument we frequently see in injury claims: judging a person’s injuries solely by the appearance of the vehicle. As we explain in What If My Car Has Little Damage but I Am Seriously Injured?, vehicle damage is evidence, but it is not a medical diagnosis.

The same principle applies here.

Seat belt use is relevant evidence. It should not replace an actual investigation into what caused your injuries.

A Real Arizona Case Shows Why the Difference Matters

In Law v. Superior Court, the injured occupants were not wearing seat belts and were thrown from their vehicle during a rollover.

The Arizona Supreme Court ultimately recognized that failure to wear a seat belt could be considered when determining damages if the defendant could prove the necessary connection between the nonuse and the injuries.

Importantly, the court distinguished between causing an accident and causing or increasing an injury.

That distinction remains a useful way to think about these cases.

A negligent driver should not automatically escape responsibility for causing a serious collision merely because the injured person failed to buckle up. At the same time, Arizona law may allow consideration of injuries that could reasonably have been prevented or reduced through seat belt use.

Every case therefore depends heavily on the evidence.

What If the Seat Belt Would Not Have Prevented My Injury?

Then the seat belt defense may be much weaker for that particular injury.

Suppose another vehicle crashes into the driver’s side of your car and the door intrudes into the passenger compartment, causing a leg injury.

The insurance company cannot simply assume that a seat belt would have prevented the injury. It may need evidence showing how restraint use would actually have changed the outcome.

Likewise, an unbelted passenger could suffer an injury from broken glass, collapsing vehicle components, airbag deployment, or other crash forces that might have occurred even while properly restrained.

This is why medical records, crash photographs, witness accounts, vehicle evidence, and expert analysis can become important.

The question is not simply, “Were you wearing your seat belt?”

The better question is, “What difference would wearing it actually have made?”

What If I Had a Medical Reason for Not Wearing a Seat Belt?

Arizona law contains an exception for certain people who possess a written statement from a physician or registered nurse practitioner explaining that they cannot wear the restraint for medical or psychological reasons.

That could be highly relevant if an insurer later argues that failing to wear a belt was unreasonable.

Other unusual circumstances may also matter. For example, there may be questions about whether a restraint was functioning properly or whether it was actually available for the seating position involved.

Do not assume that the notation “no seat belt” in an accident report resolves the entire legal issue.

Can I Recover Medical Bills, Lost Wages, and Pain and Suffering?

Potentially, yes.

Depending on the circumstances of the accident and the available evidence, an Arizona car accident claim may include compensation for losses such as medical expenses, lost income, future medical treatment, pain and suffering, and other effects of the injury.

Perez Law Group discusses these issues in more detail in our guides to compensation for lost wages after an Arizona car accident and future medical treatment after a car accident.

The seat belt dispute may affect the value of some damages, but it does not mean every category of compensation disappears.

What Should You Do If You Were Not Wearing a Seat Belt?

First, be truthful.

Do not tell the police, your doctor, an insurance adjuster, or your attorney that you were wearing a seat belt if you were not. An inconsistent story can create a credibility problem that is much harder to address than the seat belt issue itself.

Instead:

• Seek appropriate medical treatment and accurately describe how the collision occurred.
• Tell your doctors where you are experiencing pain and how your symptoms change.
• Preserve photographs of the vehicles, interior damage, bruising, cuts, and other visible injuries.
• Avoid guessing about whether a seat belt would or would not have prevented a particular injury.
• Be cautious about giving recorded statements or accepting an early settlement before the full injury picture is understood.

Seat Belts Still Save Lives

Nothing about Arizona’s seat belt defense changes the safety advice.

Wear your seat belt.

The National Highway Traffic Safety Administration reports that wearing a lap and shoulder belt in the front seat of a passenger car reduces the risk of fatal injury by approximately 45 percent and moderate-to-critical injury by approximately 50 percent.

Seat belts can also cause bruising or injuries during severe collisions because they restrain the body while tremendous forces are being transferred through the vehicle. We explain that issue in Can a Seat Belt Cause Shoulder, Chest, or Rib Injuries?.

The fact that a seat belt can sometimes contribute to an injury does not make going without one safer.

Do Not Assume You Have Lost Your Car Accident Claim

If you were injured in an Arizona accident while not wearing a seat belt, do not assume you have no case.

Another driver may still be responsible for causing the collision. Your injuries may still be significant. And an insurance company’s assertion that “the seat belt would have prevented everything” is not the same thing as proving it.

The circumstances of the crash, the type of injury, medical evidence, vehicle evidence, and Arizona law all matter.
