Incident: Fatal ATV Crash
Authority: Sgt. Tyler Ho**ig

On Wednesday, October 21, 2026, at approximately 5:50p.m., the Fond du Lac County Sheriff’s Office Communications Center received a 911 call from a passing motorist reporting an ATV crash on Walnut Rd near Century Lane in the Township of Forest. Information provided by the caller indicated an ATV was on its side near the shoulder, with a male lying near the machine who was unresponsive.

Deputies from the Fond du Lac County Sheriff’s Office responded to the scene, along with personnel from Mt. Calvary Fire, Mt. Calvary EMS, Mt. Calvary first responders, City of Fond du Lac Ambulance (Intercept), and Wisconsin Department of Natural Resources.

Upon arrival on scene lifesaving efforts were being performed on the driver and lone occupant of the ATV. ThedaStar Helicopter was requested to assist on scene, and did later arrive landing on Walnut Rd.

The preliminary investigation indicates that the ATV was traveling westbound on Walnut Road with a tow behind brush mower attached to the vehicle. While traveling westbound the driver lost control of the vehicle causing it to flip in the roadway.

The driver, a 70-year-old resident of Fond du Lac County, was pronounced deceased at the scene.

Walnut Road between County Road W and 7 Hills Road was closed for approximately two hours.

The incident remains under investigation by the Wisconsin Department of Natural Resources.

Incident: I-41 Vehicle Fire
Authority: Sgt. Brian Bednarek

On Wednesday, October 21, 2026, at approximately 1:50 a.m., the Fond du Lac County Communications Center received a 911 call reporting a box truck on fire in the northbound lanes of Interstate 41 near mile marker 90 in the Town of Byron.

A deputy with the Fond du Lac County Sheriff’s Office arrived on scene and observed that the truck was fully engulfed in flames. The Brownsville Fire Department and Lomira Fire Department also responded.

Due to the severity of the fire, the northbound lanes of Interstate 41 were initially closed at State Highway 49 in Dodge County. Traffic was detoured westbound on State Highway 49 to northbound State Highway 175, then eastbound on County Highway B, returning to northbound Interstate 41.

The truck and its contents were considered a total loss. The fire is not considered suspicious. No civilian or emergency personnel injuries were reported.

After the fire was extinguished, responders observed chunks of metal that had melted onto the Interstate 41 travel lanes. The metal had hardened, creating a traffic hazard. The Fond du Lac County Highway Department was contacted to assist with removing the metal before the roadway could be reopened.

Northbound Interstate 41 was closed for approximately four hours and reopened at 5:50 A.M.

A school bus with its stop-arm out and flashing lights means STOP — kids are crossing!

No matter where you’re headed, the rule is the same: when the stop-arm is out, you stop.

It’s easy: If the school bus stops, you need to stop, too!

Let’s protect kids getting on and off the school bus! Always stop when the stop-arm is out.

Stopping for school buses is the law in all 50 states. Following it protects young lives. Always stop when the stop-arm is out.

Today is National Move Over Day – October 17

The people working along our highways are more than a uniform or a flashing light. They’re moms, dads, sons, daughters, spouses, friends, and neighbors and they all deserve to make it home safely.

When you see flashing lights on the side of the road, slow down and move over. Give law enforcement, firefighters, EMS, highway crews, tow operators, and everyone working roadside the space they need to do their jobs safely.
Slow Down. Move Over. Help everyone get home.
