This scenario plays out every day across Clark County and Southwest Washington. Nearly one in five Washington drivers carries no liability insurance whatsoever, and countless more carry only the state minimum—coverage that can be exhausted by a single emergency room visit. When the person who hurt you cannot pay and you have uninsured motorist (UM) and underinsured motorist (UIM) coverage, that coverage steps in as your financial safety net. Vancouver Washington personal injury attorneys will all advise you that understanding how this coverage works—and carrying enough of it—may be the single most important financial decision you make as a driver.
insufficient insurance (UIM) to cover your losses. Uninsured Motorist (UM) coverage applies when the at-fault driver carries no liability insurance at all, or in hit-and-run situations where the driver is never identified. Under Washington law, UM coverage also extends to accidents caused by “phantom vehicles”—drivers who cause a collision without making physical contact with your car, such as when a vehicle swerves into your lane, forcing you off the road, and then disappears.
Underinsured Motorist (UIM) coverage fills the gap when the at-fault driver has insurance, but not enough to cover your damages. For example, if your medical bills, lost wages, and pain and suffering total $150,000 but the at-fault driver only carries $25,000 in liability coverage, your UIM policy would cover the remaining $125,000, up to your policy limits.
include medical expenses (past and future), rehabilitation costs, lost wages and diminished earning capacity, and pain and suffering. This is the core of most UM/UIM claims and often represents the most significant financial recovery available to car accident injury claim victims when the other driver is uninsured or underinsured.
At a minimum, your UM/UIM limits should match your liability limits. But for most families, the right amount is substantially higher.
As a general guideline, we advise clients to carry at least $100,000 per person / $300,000 per accident in UM/UIM coverage, and ideally $250,000/$500,000 or higher if your budget allows. If you have significant assets to protect—a home, retirement accounts, investments—an umbrella policy that extends your UM/UIM coverage to $1 million or more is a worthwhile investment.
Third-party liability coverage is the at-fault driver’s insurance. You pursue a claim against their policy first. If their limits are exhausted and your damages exceed what they paid, your UIM coverage kicks in to cover the difference.
Personal injury protection (PIP) is a no-fault coverage under your own policy that pays medical expenses and lost wages regardless of who caused the accident. PIP coverage activates immediately and can bridge the gap while you pursue your UM/UIM claim. PIP benefits are typically subject to subrogation—meaning your insurer may seek reimbursement from any UM/UIM recovery—but Washington’s Made Whole Doctrine generally prevents your insurer from exercising subrogation rights until you have been fully compensated for all your losses.
Health insurance will cover medical treatment, but it does not compensate you for lost wages, pain and suffering, or other non-medical losses. Additionally, health insurance often involves copays, deductibles, and network restrictions. UM/UIM coverage fills these gaps.
Collision coverage covers physical damage to your vehicle regardless of fault, making it essential for hit-and-run situations where the at-fault driver is never identified (since Washington’s UM property damage coverage requires the uninsured driver to be identified). However, collision coverage does not compensate for bodily injuries.
Anti-stacking provisions: Washington law allows insurers to include “anti-stacking” language preventing you from combining UM/UIM limits across multiple policies. Under RCW 48.22.030(6), if you are covered under more than one UM/UIM policy, the total available coverage may be limited to the highest single policy limit—not the combined total.
Arbitration is the most common resolution mechanism for UM/UIM disputes in Washington. Most auto policies include mandatory arbitration clauses, and Washington courts have consistently upheld them. If the net recovery you seek is $50,000 or less, the case is typically resolved through mandatory arbitration. For larger claims, the case may proceed to trial in Superior Court.
The statute of limitations for a UM/UIM claim follows the same three-year deadline that applies to personal injury actions generally under RCW 4.16.080. However, because UM/UIM claims involve contractual rights under your insurance policy, the applicable deadline can be complicated. Do not wait—consult an attorney promptly after any accident involving an uninsured or underinsured driver.
Call the police and insist on an accident report—this is critical for documenting the other driver’s lack of insurance and serves as corroborating evidence if you need to file a UM claim involving a phantom vehicle.
Collect information from all parties, including the other driver’s name, contact information, vehicle details, and insurance information (or lack thereof). Photograph the scene, vehicle damage, and your injuries.
Seek medical treatment immediately, even if your injuries seem minor. Conditions like whiplash and soft tissue injuries often worsen in the days following a collision, and gaps in medical treatment can undermine your claim.
Notify your insurer of the accident and your intent to file a UM/UIM claim. Washington law requires that phantom vehicle accidents be reported to law enforcement within 72 hours.
Consult a Vancouver WA personal injury lawyer before accepting any settlement offer from your insurer or the at-fault driver’s insurer. Early legal guidance can prevent costly mistakes—such as accepting the at-fault driver’s policy limits without preserving your right to pursue a UIM claim.
No, but your insurer must offer it, and it automatically attaches at your liability limits unless you reject it in writing. Given that nearly 20% of Washington drivers are uninsured, we consider UM/UIM coverage essential.
Yes, but collecting on a judgment against someone who could not afford insurance in the first place is often impractical. UM/UIM coverage provides a reliable source of recovery.
Yes. If you are struck by an uninsured or underinsured driver while walking or riding a bicycle, your own UM/UIM policy covers your injuries.
This is exactly what UIM coverage is designed for. After exhausting the at-fault driver’s liability limits, you file a UIM claim with your own insurer for the remaining damages up to your policy limits.
Yes, and if they do, you may have a separate cause of action for insurance bad faith under Washington’s Insurance Fair Conduct Act (RCW 48.30.015) and the Consumer Protection Act (RCW 19.86). Bad faith claims can result in treble damages and attorney fees.
