Multi-Vehicle Crashes on Seattle Highways
Major freeway interchanges like the one between State Route 520 and I-5 in Seattle are frequent sites for injury crashes, especially during peak travel times. With dense traffic volumes, fast-moving vehicles, and frequent lane changes, even a brief lapse in judgment or visibility can trigger a serious two-car collision.
In Monday’s incident, the collision occurred during the heart of evening rush hour—a time when traffic patterns are unpredictable, and stopping distances are reduced due to congestion. Blocked lanes during these times not only delay drivers but also increase the risk of secondary accidents and emergency response challenges.
Seattle drivers are urged to exercise caution near major interchanges and remain alert to rapidly changing traffic conditions. Slowing down and maintaining awareness of surrounding vehicles can reduce the likelihood of rear-end or side-impact crashes in these tight traffic corridors.
For those injured in multi-vehicle freeway crashes, dealing with medical recovery, insurance logistics, and vehicle repairs can be overwhelming. It’s important to document the incident thoroughly and seek proper care and legal support when necessary.
