State Incentives

Idle Reduction Grant Program

The Wisconsin Department of Commerce provides grants to freight motor carriers headquartered in Wisconsin to purchase and install idle reduction units on heavy-duty tractor trucks produced in Model Year 1999 or later. Eligible applicants will receive a reimbursement of up to 50% for the cost of idle reduction equipment and installation. The application period opens on July 1 of every year; grants are not available for idle reduction equipment purchased or installed prior to July 1 in the year the application is submitted. The program will award $2 million per year in grants for the 2007-2008 and 2008-2009 award periods, and $1 million per year in grants for the 2009-2010 and 2010-2011 award periods. Other conditions may apply. (Reference Wisconsin Statutes 560.125)

State Laws and Regulations

Idle Reduction Weight Exemption

Any vehicle or combination of vehicles equipped with fully functional idle reduction technology may exceed the state's gross and axle weight limits by up to 400 pounds (lbs) to compensate for the additional weight of the added idle reduction technology. To be eligible for the weight exemption, the vehicle operator must be able to prove, by written certification, the weight of the idle reduction technology and, by demonstration or certification, that the idle reduction technology is fully functional at all times. The weight exemption cannot exceed 400 lbs or the certified weight of the unit, whichever is less. (Reference Wisconsin Statutes 348.15 (3)(f))
