Chaos unfolded on the southbound Interstate 41 near County Trunk DW in the Town of Addison when a rollover crash halted traffic and initiated a rapid response from emergency services. The Washington County, Wisconsin, Sheriff's Office shared on social media that they received multiple reports at 2:53 p.m. yesterday about the accident that sparked swift action from local law enforcement and fire departments.

First responders, among them deputies from the Washington County Sheriff's Office and the Allenton Fire Department team, rushed to the scene to help. The sheriff's office reported that, while they were en route, a separate report came in regarding a person having a medical emergency in a different vehicle. An overturned SUV was discovered in the midst of the southbound lanes, its occupants already being aided by bystanders, and would soon be transported with suspected minor injuries to a local hospital for further evaluation.

The compounding vehicular mishap occurred when a full-size SUV, towing a trailer, inexplicably began to swerve, causing mayhem as it struck another vehicle. According to a communication from the Washington County Sheriff's Office, "The preliminary investigation determined that the SUV towing the trailer began to swerve across both southbound lanes as a result of the driver’s medical emergency," subsequently hitting the other SUV and resulting in its turnover. The driver, amidst the crisis, was entrapped in the veering vehicle caught in the median barrier; they were attended to by family members until deputies could extricate them and facilitate their hospital transportation. 

Investigators say the inquiry into the incident is still in its early stages, but initial reports depict a chaotic scene in the moments leading up to the crash. Traffic on both the northbound and southbound lanes of the interstate was intermittently closed for approximately three hours to allow for vehicle removal and debris cleanup. The West Bend Fire Department and the Wisconsin State Patrol responded to the scene to assist with clearing the aftermath. Local agencies worked together to restore normal traffic flow and ensure public safety.
