The crash occurred on April 9 at approximately 10 p.m. on westbound SR 524. According to available information, a 22-year-old man from Stanwood allegedly struck two vehicles while attempting to pass traffic. One of the impacted vehicles, driven by a 17-year-old boy with three juvenile passengers, veered into oncoming eastbound traffic and rolled multiple times before striking a utility pole.
The passengers in that vehicle were ages 11, 13, and 15. A fourth vehicle was struck by debris, though its driver was not injured. All drivers and passengers involved in the three main vehicles were taken to hospitals for treatment of serious injuries.

What Authorities Review in Multi-Vehicle DUI-Related Highway Crashes
When multiple vehicles are involved in a highway crash, investigators often focus on the sequence of impacts. This helps establish how one collision may have triggered additional crashes across lanes of travel.
Driver actions leading up to the incident are also reviewed, including lane changes and passing maneuvers. These details can help clarify how traffic movement contributed to the event.
In cases involving suspected impairment, officers typically document driving behavior, roadway conditions, and post-crash observations. Injury assessments and vehicle damage patterns are also used to reconstruct how the collision developed across multiple impact points.
