Vehicle obstruction creates smoke plume near South Spokane Street At approximately 20:58 UTC on December 22, 2025, a disabled vehicle stalled on the right‑hand two lanes of northbound Interstate 5 at milepost 163, producing a visible smoke plume that prompted an immediate emergency response [1]. The incident occurred near South Spokane Street, a critical corridor for commuter traffic in Seattle [1]. Authorities classified the situation as “developing,” with details about the vehicle’s condition still pending [1].

Multi‑agency response mobilized within minutes The Washington State Patrol, the local incident‑response team, and Seattle fire crews arrived on scene to secure the area and begin vehicle removal [1]. Coordinated efforts aimed to protect responders, contain any potential fire, and manage traffic flow around the blockage [1]. Communication among agencies was continuous, ensuring that safety protocols were upheld throughout the operation [1].

HOV lane opened to all traffic to alleviate congestion To mitigate the impact of the lane closure, officials opened the high‑occupancy vehicle lane to all drivers, allowing it to serve as a temporary detour for the blocked northbound lanes [1]. Traffic controllers directed vehicles onto the HOV lane while crews worked on the disabled vehicle [1]. Motorists were warned to expect significant delays along the northbound I‑5 corridor as the incident progressed [1].

No injuries reported; situation remains fluid Emergency personnel confirmed that no injuries occurred among responders or motorists at the time of reporting [1]. The blockage persisted as crews continued to assess and address the vehicle’s condition [1]. Updates were promised as the incident evolved, with authorities monitoring the scene for any changes [1].
