Is Washington a No Fault State for Car Accidents?

When you’re in a car accident in Washington, the last thing that may be on your mind is fault, especially when you’re certain it doesn’t lie with you. But fault makes a difference in how you can recover compensation for your personal injury claim and being in a no-fault state or an at-fault state makes a huge difference in your case.

Understanding the difference between these two systems is important because it affects who pays for your injuries, how much compensation you may receive, and what happens when more than one driver shares responsibility.

What Is the Difference Between an At-Fault and No-Fault State?

The biggest difference between at-fault and no-fault states is mainly two things: whose insurance pays for the damages and losses after a car accident and whether someone must establish fault before receiving benefits.

In an at-fault state, the driver responsible for causing the accident is generally liable for the losses. An injured person can file a claim against the at-fault driver’s liability insurance to recover compensation for medical expenses, pain and suffering, and other losses.

In a no-fault state, drivers generally turn to their own personal injury protection (PIP) insurance for certain expenses, regardless of who caused the accident. This allows injured people to receive benefits for covered medical expenses and, depending on the policy and state, a portion of their lost income without first proving another driver was responsible.

No-fault insurance doesn’t mean drivers are never held responsible for causing accidents. However, it can limit an injured person’s ability to seek compensation from the other driver. Depending on the state, you can only pursue a personal injury lawsuit if your injuries are serious enough or your financial losses exceed a certain amount. 

Is Washington a No-Fault or At-Fault State?

Washington is an at-fault state for car accidents, meaning the driver responsible for causing a collision is generally liable for the resulting losses. Injured drivers and passengers can pursue compensation through the at-fault driver’s liability insurance or file a personal injury lawsuit.

The injured person does not need to meet a specific injury severity threshold before pursuing compensation from a negligent driver. However, they must still establish that the other driver’s negligence caused their injuries.

Washington also follows a pure comparative negligence rule, meaning more than one driver can be at fault for the accident. An injured person can still recover compensation even if they were partially responsible, but their compensation is reduced by their percentage of fault.

Who Decides Who Is at Fault in a Washington Car Accident?

The police and insurance companies can both investigate an accident, but they don’t necessarily reach the same conclusion.

A police officer may issue traffic citations if they believe a driver broke the law, but a citation doesn’t automatically establish liability for someone’s injuries. Likewise, a driver who wasn’t cited can still be held responsible.

Because fault determines who pays after a car accident, insurance companies conduct their own investigations, reviewing police reports, witness statements, and other evidence to determine who was responsible. However, their decisions aren’t necessarily final. If either driver disputes the insurer’s findings, they can challenge them through negotiations or a personal injury lawsuit. If the case goes to trial, a judge or jury may ultimately decide who was responsible.

How Does Washington’s At-Fault Insurance System Work?

In Washington, the driver who causes an accident is generally responsible for the resulting losses. For example, if another driver runs a red light and hits you, their insurance would typically cover your medical expenses, lost wages, and other qualifying losses, up to the limits of their policy.

However, that doesn’t mean the other driver’s insurance company automatically pays everything you’re owed. The insurer will evaluate who caused the accident, the extent of your injuries, and how much compensation you’re entitled to receive. It may also dispute certain expenses or argue that you were partly responsible for the collision.

How Much Liability Insurance Does Washington Require?

Because drivers can be held financially responsible for the injuries they cause, Washington requires most motorists to carry liability insurance. According to the Washington Department of Licensing, the minimum bodily injury coverage amounts are:

• $25,000 per person: the maximum the insurer will pay for injuries to one person.
• $50,000 per accident: the maximum the insurer will pay for injuries to multiple people in the same collision.

The problem is that even a relatively straightforward accident can result in medical bills, missed work, and other expenses that exceed those limits. If someone suffers a serious injury requiring surgery, rehabilitation, or ongoing treatment, $25,000 may cover only a fraction of their losses.

Being entitled to compensation and having enough insurance available to pay it are two different things. The at-fault driver may still be personally responsible for losses beyond their insurance limits, although actually recovering that money can be difficult.

What Is Personal Injury Protection Insurance?

Even when another driver is clearly responsible for an accident, getting their insurance company to pay for your injuries can take time. Meanwhile, medical bills may be piling up, and you could be missing work because of your injuries.

That’s where personal injury protection comes in. It’s a type of no-fault insurance that helps cover certain expenses after a car accident, regardless of who caused it. Instead of waiting for the other driver’s insurance company to accept responsibility, you can receive benefits through your own insurance policy.

In Washington, PIP coverage can help pay for:

• Medical expenses: At least $10,000 per injured person for covered medical and hospital expenses.
• Lost wages: Partial income replacement if your injuries prevent you from working for at least 14 consecutive days.
• Household services: Help paying for everyday tasks you can no longer perform because of your injuries.
• Funeral expenses: Limited benefits following a fatal accident.

Washington doesn’t require drivers to carry personal injury protection, but insurance companies must offer it. If you don’t want the coverage, you must reject it in writing. Otherwise, your insurer will include it in your policy and charge you for it.

Using PIP doesn’t prevent you from pursuing a personal injury claim against the at-fault driver. You can still seek compensation for losses that PIP doesn’t cover. However, you generally can’t recover compensation for the same expense twice. If PIP pays some of your medical bills and you later receive a settlement covering those bills, your insurer may be able to seek reimbursement for what they’ve already paid.

What if the At-Fault Driver Doesn’t Have Enough Insurance?

Just because Washington requires drivers to carry liability insurance doesn’t mean everyone has it. Some drivers are uninsured, while others carry only the minimum required coverage. Unfortunately, those policy limits may not come close to covering the costs of a serious injury.

Suppose another driver causes an accident that leaves you with $75,000 in medical bills and lost wages. If that driver only carries Washington’s minimum $25,000 in bodily injury liability insurance, there’s a $50,000 difference between your losses and the amount their insurance can pay.

You may be able to pursue the remaining compensation directly from the at-fault driver, but collecting that money can be difficult, particularly if they don’t have the financial resources to pay. This is where uninsured/underinsured motorist (UM/UIM) coverage can make a difference.

Uninsured motorist (UM) coverage helps protect you when the driver responsible for the accident doesn’t have applicable liability insurance. It may also apply to certain hit-and-run accidents. Underinsured motorist (UIM) coverage helps when the responsible driver has insurance, but their available coverage isn’t enough to compensate you for your injuries.

Both of these types of coverage are part of your own auto insurance policy. So, instead of relying entirely on the other driver’s insurance, you may be able to turn to your own insurer for additional compensation, up to your available coverage limits.

Is Uninsured or Underinsured Motorist Coverage Required in Washington?

Like PIP, UM and UIM is optional coverage in Washington, but insurance companies generally must offer it when you purchase an auto insurance policy. If you don’t want it, you must reject it in writing.

Unlike PIP, however, UM and UIM coverage isn’t designed to pay certain expenses regardless of who caused the accident. You generally must establish that another driver was legally responsible for your injuries and that the driver was uninsured or didn’t have enough applicable insurance to cover your losses.

Having UM or UIM coverage doesn’t necessarily mean your insurer will automatically pay the difference between your losses and the other driver’s insurance limits. Your own insurance company may dispute the amount of compensation you’re entitled to receive. 

Can You Sue an At-Fault Driver in Washington?

Because Washington uses an at-fault-based system, you can file a personal injury lawsuit against a negligent driver who caused your injuries. Unlike some no-fault states, Washington doesn’t require your injuries meet a certain severity threshold before you can sue.

However, that doesn’t mean every car accident needs to result in a lawsuit. Many car accident claims are resolved through negotiations with the at-fault driver’s insurance company. A lawsuit may become necessary when the insurance company refuses to accept responsibility, disputes the extent of your injuries, or offers a settlement that doesn’t adequately compensate you for your losses.
