The speed limit has been in place off and on since 2006 but will expire July 1 if lawmakers don’t act.

Supporters say the limit helps reduce the number of crashes and fatalities. Previously, Wisconsin had no speed limit on snowmobilers. As many as three dozen or more people have died in one year in Wisconsin snowmobile crashes.

The plan, which is supported by a key snowmobile group, is expected to pass the Assembly with bipartisan support.

The Senate would also need to act on the measure before Gov. Jim Doyle, who has supported the limit in the past, could sign it into law.
