Car accidents can happen anywhere, from a quiet Spokane intersection to a rainy stretch of I-5 near Seattle. When they do, knowing your rights under Washington law can make the difference between a fair settlement and an uphill battle.
At West Coast Trial Lawyers, we help clients across Washington recover compensation after serious crashes. Below, we break down ten of the most important Washington car accident laws every driver should know so youโre ready to protect yourself, your health, and your claim.
1. Washington Follows a Fault-Based System

Washington is a fault-based state, meaning the driver who causes the crash (and their insurer) is financially responsible for injuries and property damage. Victims can file:
- A claim with the at-fault driverโs insurer
- A claim with their own insurer
- A personal injury lawsuit in civil court
Because liability can be disputed, strong evidence like crash reports, witness statements, and scene photos is critical to proving who was truly at fault.
2. Comparative Negligence Can Reduce Compensation
Under RCW 4.22.005, Washington uses a pure comparative negligence ruling in car accidents with varying degrees of liability. This means you can recover damages even if you share some blame, but your award will be reduced by your percentage of fault.
For example, if youโre 20% at fault for a $50,000 claim, youโll still receive $40,000. However, insurance companies often exploit this rule to minimize payouts, so working with an experienced lawyer helps keep blame from being unfairly shifted onto you.
3. Minimum Auto Insurance Requirements
According to RCW 46.29.090, Washington State requires all drivers to maintain a minimum car insurance policy that has at least the following coverages:
- $25,000 for injury or death of one person
- $50,000 for injury or death of two or more people
- $10,000 for property damage
If you cause or are involved in a car accident while uninsured, it can lead to fines, license suspension, and even vehicle impoundment. To most people’s surprise, roughly 19% of all Washington drivers are uninsured according to data from the Insurance Information Institute, with this statistic in mind, itโs smart to add uninsured/underinsured motorist coverage for extra protection.
4. You Must Stop and Report After an Accident
No matter what kind of car accident you have been involved in, you must stop and take action. Failing to stop after an accident is illegal under RCW 46.52.020. Drivers must:
- Stop immediately at or near the scene,
- Provide their name, address, and vehicle registration,
- Render aid if anyone is injured, and
- Report the crash to law enforcement.
If an officer doesnโt investigate the accident scene, you must file a report within four days through the Washington State Patrol (WSP) Collision Records Section or the online crash reporting system.
5. The Statute of Limitations Is Three Years
Under RCW 4.16.080, most car accident victims have three years from the date of the crash to file a personal injury or property damage claim to recover compensation against the at-fault party.
This deadline applies whether youโre filing against a negligent driver, employer, or manufacturer and if you miss it, the statute of limitations takes into effect and courts will dismiss your case. However, claims against government agencies, require a formal notice of claim within shorter time frames and any claims must be filed at an urgent pace.
6. Hit-and-Run Violations Carry Serious Penalties
Leaving the scene of an accident can lead to jail time, license loss, and steep fines. According to RCW 46.52.020, fleeing after a collision that has resulted in significant property damage is a misdemeanor and fleeing after an injury or fatality is a felony.
If youโre a victim of a hit-and-run, immediately file a police report and contact your insurer. Your uninsured motorist coverage often applies in these situations, helping you recover even if the other driver isnโt found.
7. Distracted Driving Laws Are Strictly Enforced
Washingtonโs Driving Under the Influence of Electronics Act (RCW 46.61.672) prohibits drivers from holding a cell phone, even at red lights. Violations can result in hefty fines, insurance penalties, and possibly even license suspension in severe instances.ย
If a driver causes a crash while texting or using a handheld device, itโs considered negligence per se, a legal presumption of fault that strengthens the accident victim’s injury claim. As a result, anyone who has caused an accident due to distracted driving will not only be held accountable, but can become liable for damages in a personal injury claim.ย
8. Seat Belt and Child Safety Requirements
Seat belt laws under RCW 46.61.688 require all passengers to buckle up. Additionally, RCW 46.61.687 mandates:
- Children under 8 years old must ride in an appropriate child restraint unless 4โ9โ or taller.
- Violations can lead to fines and reduced injury compensation if nonuse contributed to harm.
Proper restraint use also matters in settlement negotiations because insurers may argue โseat belt negligenceโ to reduce payouts.
9. Washingtonโs DUI and Drugged Driving Laws
Driving under the influence of alcohol or drugs is thoroughly outlined in RCW 46.61.502. According to state law, legally intoxication counts if you have:
- A BAC of 0.08% or higher, or
- 5 nanograms of THC per milliliter of blood.
Even prescription drugs can lead to impairment charges and as such, drunk or drugged drivers can face criminal prosecution, license suspension, and civil liability for any resulting injuries. Accident victims may also pursue enhanced damages in cases of extreme recklessness.
10. Medical Treatment and Documentation Protect Your Case
After a crash, getting prompt medical care isnโt just good health advice, it’s very important for your legal claim. Insurers often dispute delayed treatment, claiming your injuries werenโt caused by the accident.
See a doctor within 24โ48 hours and keep copies of all records, prescriptions, and bills. Detailed medical documentation links your injuries to the crash, helping maximize compensation for pain, suffering, and long-term care.
