background
Drivers in Seattle lost approximately 30 hours due to congestion in 2020, making Seattle one of the worst cities for traffic in the country. 
Seattle, Washington is home to more than just the Space Needle and killer seafood—it’s also the hometown of pretty gnarly traffic. Back in 2017, Seattle was one of the worst cities for traffic in the nation, but time spent in congestion is dozens of hours lower now, thanks to the pandemic. But Seattle congestion has been slowly increasing since its drastic drop in 2020—and it looks like it will be going up from here.

Why is Seattle traffic so bad?

As a major city in Washington, Seattle attracts loads of commuters coming in for daily work. But that’s not the only reason Seattle sees bad traffic. 

Population size 

Seattle's population was 761,100 in 2020, according to Seattle’s 2021 Traffic Report. But the Seattle metropolitan area—which encompasses Seattle proper and its surrounding cities and suburbs—has a population of closer to 4,000,000. With many of these residents commuting through and to Seattle each day, you’re looking at a pretty congested city. 

Major chokepoints

Seattle’s Traffic Report
found 10 top traffic hotspots in 2020. The worst three were Mercer Street @ Fairview Ave N, Montlake Bridge, and East Marginal Way S @ Alaska St
There are also a few intersections in Seattle where blocking the box (getting stuck in an intersection during traffic light changes) happens regularly:
  • Fairview and Valley
  • Howell and Ninth
  • Fremont and 324th
  • Fifth and Mercer
  • Mercer and Westlake
  • Rainer and Forrest
  • Mercer and Dexter

Driving habits

Seattle lacks a reputable bus and light rail system, making it difficult for residents and commuters to rely on public transportation for their daily commutes. 
On top of that, many of Seattle’s city and residential streets are maddening, switching from one- to two-way without apparent warning.

How to navigate Seattle traffic like a pro

There are times when it feels like bad traffic is taking years off your life—it’s just that frustrating!
But bad traffic is more than just an annoyance. It can also significantly increase your chances of getting into a car accident—and it can
even cause your car insurance rate to shoot up.
 
Knowing how to drive in Seattle traffic is imperative to staying happy and sane—and safe on the roads. 
Here are some of our favorite tips for navigating Seattle traffic like a pro. 
  • Avoid rush hour if you can. Seattle rush hour starts around 6:30 am and can often go all the way until 9 am—but it’s worse in the evenings from 5-6 pm
  • Use a traffic app to find the best routes. Knowing the best routes for avoiding traffic is great—and it’s even better to get real-time updates on things like accidents or roadblocks that could throw a wrench in your commute. 
  • Keep calm and drive on. You might feel like aggressively weaving through traffic is your best option, but in reality, staying calm and
    driving undistracted
    will keep you safe and help keep your record clean. Avoid loud music and distractions when you’re behind the wheel (and yeah, that means you shouldn’t be mixing cream and sugar into your morning coffee while you drive).

FAQs

Seattle’s side streets can be tricky if you aren’t paying attention—some one-way streets look like two-ways when there are no parked cars taking up space. And, of course, Seattle’s congestion is hard for any driver who doesn’t like traffic.
The best time for driving in Seattle is outside of rush hour. That means driving around 9 am-4:30 pm or after 7 pm.
