Town of Harmony, WI – Injury Crash Involving Overturned Semi-Truck on I-90 Near MM 168

‍Town of Harmony, WI (March 17, 2026) – A crash involving a semi-truck and an SUV led to injuries and a hazardous material spill Monday, March 16, near Janesville. Emergency units responded around 11:48 a.m. to Interstate 90 near mile marker 168 after reports that a tanker truck had overturned.

Officials said the crash began when an SUV lost control and struck a tanker truck traveling along the interstate. The impact caused the tanker to slide off the roadway into a nearby ditch before overturning.

Emergency crews arrived and found the tanker carrying about 5,500 gallons of a highly flammable resin solution. The spill created a dangerous situation, prompting officials to call in the Rock County Hazardous Materials Team for assistance.

Hazmat specialists used a drone to evaluate the crash scene from a safe distance. This aerial review helped responders understand the extent of the spill and identify potential safety risks.

A specialized response team then entered the area identified as the “Hot Zone,” which marks the section with the highest contamination risk. The team performed atmospheric monitoring and documented the area using photos and video.

Authorities have not released information about the number of people injured or the severity of the reported injuries. Investigators continue reviewing the circumstances that led to the crash.

Our thoughts remain with those injured as they receive care and work toward recovery.

What Should I Do if I Was Hurt in a Truck Accident in Wisconsin?

If you were hurt in a truck accident in Wisconsin, the most important steps include seeking medical attention, reporting the crash, documenting the scene, and keeping records related to your injuries and expenses. Taking these steps helps protect your health and creates important documentation that may become useful later.

Truck accidents often involve larger vehicles and heavier loads than typical passenger car collisions. Because of this, the impact can cause serious injuries even when the crash occurs at moderate speeds. People involved in these accidents may experience neck strain, back injuries, head trauma, or breathing issues if hazardous materials are present. Some symptoms appear immediately, while others develop hours after the crash.

Medical evaluation plays an important role after any truck accident. Doctors can identify injuries that may not be obvious at first and recommend follow-up treatment if necessary. Medical records also document the injury and the care received, which can help track recovery over time.

It also helps to document details about the crash scene whenever possible. Photos of vehicles, road conditions, and surrounding traffic signs can help preserve information from the moment of the accident. Keeping copies of medical bills, prescriptions, and repair estimates can also help people stay organized while managing recovery and insurance claims.

Truck accidents sometimes involve multiple parties, including drivers, trucking companies, or cargo handlers. Because several insurance policies and regulations may apply, the claims process can become complex. A truck accident lawyer can review accident reports, medical records, and insurance information to help explain what options may be available under Wisconsin law.
