Reporting a snowmobile crash incident

A "reportable" snowmobile crash incident is any incident (regardless of the number of snowmobiles involved) that results in a fatality or an injury that requires medical treatment by a physician.

Wisconsin law requires every snowmobile operator involved in a "reportable" incident to report the incident without delay to law enforcement officials. In addition, within 10 days of the incident, the operator must submit a written report on Form 4100-174 [PDF] to the Department of Natural Resources.

Some visitors to this site have reported having difficulty when attempting to open the crash incident report in their internet browser. The online fillable form is designed to work with Microsoft Internet Explorer.

If you are unable to download the online form above, forms are also available from DNR offices, sheriff's departments and many local police departments. Additionally, forms may be requested at the address below or by email.

Completed forms may be emailed to the DNR (instructions are included in the form) or mailed to:
