Car accident guide and data hub for the Seattle-Tacoma area

If you were just in a crash somewhere across the Seattle-Tacoma area, anywhere from Everett down to Olympia, the next few days matter more than they should have to. This page pulls together the local crash numbers, the specific roads where wrecks concentrate, and the Washington deadlines that quietly decide whether you keep any right to recover.

What the numbers say about our roads

Washington roads are getting safer again after a rough run. The Washington Traffic Safety Commission's preliminary count for 2024 was 731 people killed in traffic crashes statewide, a 9.6 percent drop from the prior year, which had been the deadliest on state roads in 33 years.¹ The longer trend is harder to shrug off than a single year's decline suggests. Washington's annual fatalities had climbed from 462 in 2014 to 810 in 2023 by the state Department of Transportation's count, about 75 percent, and serious injuries reached 3,413 that year.²

The causes are not a mystery. Impairment by alcohol or drugs was involved in 348 of the 2024 deaths, about 48 percent of the total.¹ Speed was a factor in 247, roughly a third, and most of those speeding drivers had also been drinking or using drugs.¹ Pedestrians accounted for 155 of the deaths and motorcyclists for 113, with distraction tied to another 138.¹

Most of the region's traffic funnels onto a short list of corridors: Interstate 5 and Interstate 405, State Route 167 through the Kent Valley, and State Route 99 through Seattle. Those numbers all run against an official target. Washington's Target Zero plan commits the state to bringing traffic deaths and serious injuries down to zero by 2030,³ and Seattle and Tacoma adopted the same goal through their own Vision Zero programs.

Seattle's deadliest streets

One corridor tops the city's own crash data. Aurora Avenue North (State Route 99) is the street SDOT treats as its highest safety priority, a 7.6-mile run that accounted for about 17 percent of all traffic deaths citywide between 2015 and 2019.⁴ SDOT's own tally found that over a single five-year span, 18 people were killed on Aurora between Mercer Street and North 145th Street, and 15 of them were on foot.⁵

The same setup, drivers moving fast on a wide arterial while people try to cross, drives Seattle's other problem streets. Rainier Avenue South and Martin Luther King Jr. Way South both carry active SDOT safety-corridor work, with protected bike lanes and crossing upgrades going in on segments that run from Judkins Park toward Rainier.⁶ The 2024 Seattle Transportation Levy set aside roughly $30 million specifically for Aurora, and SDOT has already added head-start walk signals and no-turn-on-red restrictions along it.⁴

There is some real progress in the trend. SDOT reports that Seattle's traffic deaths have fallen every year since a 2021 peak, though the count is still higher than in 2015, when the city started Vision Zero.⁶

Tacoma and Pierce County

Tacoma set its own clock. In 2020 the City Council passed Resolution 40559, committing to end traffic deaths and serious injuries in the city by 2035.⁷ The change drivers notice most is speed. Since January 2023 the default limit on Tacoma residential streets has been 20 mph, and four neighborhood business districts (6th Avenue, Old Town, McKinley Hill, and Lincoln) came down from 30 to 25 mph.⁷

The city runs formal road safety audits on the corridors where crashes cluster. Recent audits covered South Tacoma Way, South Yakima Avenue, and South Pine Street, and Tacoma has expanded automated traffic-camera enforcement at high-risk locations.⁷ The crash data behind those decisions comes from WSDOT and gets refreshed every April.⁷

In the first hours after a crash

Right after a wreck, a few plain steps protect both your health and any later claim. Call 911 if anyone is hurt or vehicles are blocking travel lanes, and let the responding officer document the scene, because that police report can satisfy the state filing requirement for you.⁸ See a doctor even if you feel fine, since neck and back injuries from a collision often surface a day or two later, and a gap in treatment is the first thing an insurer points to. Photograph the vehicles, the intersection, and any skid marks or signal timing before cars get moved. If you were on Aurora, Rainier, or another arterial with camera enforcement, write down the nearest cross street, which makes any footage easier to locate.

What Washington law requires after a crash

Washington puts a reporting duty directly on drivers. Under RCW 46.52.030, if a crash kills or injures anyone, or causes property damage of $500 or more to any one person, a driver has to file a written collision report within four days.⁸ There is one exception. If a law enforcement officer investigates the crash and files a report, that covers the obligation for you.⁸ So if the Washington State Patrol, Seattle Police, or Tacoma Police worked your scene and wrote it up, the state report is handled. If no officer came, the four-day clock is on you.

Get a copy of that report once it exists. It fixes the location, the vehicles involved, the road conditions, and whether anyone was cited, and it is usually the first document an insurer asks to see.

The deadline that can end your claim

The deadline that matters most is the one nobody mentions at the scene. Under RCW 4.16.080, you generally have three years from the date of the crash to file a personal injury lawsuit in Washington.⁹ Miss it and a court will almost always dismiss the case no matter how clearly the other driver was at fault. Three years sounds like plenty right after a wreck. It isn't, once you account for medical treatment that has to run its course before anyone can value the claim, and insurance talks that can stall for months.

One local twist catches people off guard. If a city, county, or state vehicle was involved, or a poorly maintained public road contributed, you have to file a formal tort claim on the standard state form and then wait 60 days before you can sue the government entity, under RCW 4.96.020.¹⁰ The three-year clock pauses during those 60 days, but the extra step is easy to miss if you don't know it's there.

Finding an attorney

If your injuries are serious or the insurer is disputing what happened, it helps to talk to someone well before that three-year clock runs short. You can find a personal injury attorney through the thatcarhitme.com legal directory.
