Wisconsin Commercial driver license (CDL) - Overview

Commercial driver licenses (CDL) are required to operate vehicles that:
  • Weigh over 26,000 pounds, determined by the highest of the following weights:
    • manufacturer's gross vehicle weight rating (GVWR)
    • manufacturer's gross combination weight rating (GCWR) when the towed unit has a GVWR, registered weight or actual gross weight over 10,000 pounds
    • actual weight
    • registered weight
  • Carry hazardous materials that require placarding under federal law.
  • Are designed or used to carry 16 or more persons including the driver (buses and some school buses). There are federal and state regulations governing the operation of commercial motor vehicles.
Wisconsin CDL law requires:
  • A classified licensing system.
  • Issuing of only one license to each driver.
  • Testing of commercial drivers, who must pass a knowledge test and driving skills test in the type of vehicle they drive.
    • School bus drivers are required to pass a knowledge test and abbreviated driving skills test at each renewal in addition to providing proof of physical fitness in the form of a completed MV3030B or valid Federal Medical Certificate.
    • Hazardous materials (Hazmat) drivers who are renewing, transferring or applying for the "H" endorsement for the first time require a background check, including fingerprinting. Drivers are also required to complete the hazardous materials endorsement application and pass the "H" knowledge test.
  • Enforcement of the law through the Commercial Driver License Information System (CDLIS), a computer network of all states.
  • Enforcement of CDL disqualifications for alcohol and serious traffic violations such as a BAC of .04 in a commercial motor vehicle, and speeding in excess (15 mph or more) in a commercial motor vehicle.

Disqualification
A disqualification is the withdrawal of a person's privilege to operate a commercial motor vehicle.

A driver license is not required to move non-registered farm machinery on a highway between fields or between a farm and a field. However, a Farm Service Wisconsin CDL is available for a person who is employed by a farm service industry for 180 days or less per calendar year.

Who is exempt from CDL licensing in Wisconsin?

Federal law allows states the option to waive certain kinds of drivers from the requirement to obtain a Wisconsin CDL. In Wisconsin, the following drivers are not required to hold a CDL:
  • Fire fighters and rescue squad members are not required to hold a Wisconsin CDL to drive properly equipped emergency or fire fighting vehicles. However, if you hold a Wisconsin driver license but operate a fire fighting vehicle in another state, you may be required to obtain a Wisconsin CDL.
  • Recreational vehicle operators (owned or leased motor home, fifth wheel mobile home or touring mobile home, provided it isn't longer than 45 feet) not engaged in commercial activity are not required to hold a Wisconsin CDL.
  • A farmer, the farmer's family members, and/or the farmer's employees are not required to hold a Wisconsin CDL to drive a commercial motor vehicle owned or leased by the farmer, provided the vehicle is not used in "for hire" carriage, is transporting farm supplies, produce or machinery to or from the farm and is within 150 miles of a farm in Wisconsin, Minnesota or Iowa. The farm supplies that a farmer may transport without obtaining a Wisconsin CDL may include hazardous materials. However, a farmer driving a commercial motor vehicle with double or triple trailers or designed to carry or actually carrying 16 or more passengers must have a Wisconsin CDL with proper endorsements.
  • Back-up (substitute or replacement) snowplow drivers (includes snow or ice removal by plowing, salting or sanding) for local units of government (defined as a county, city, village, town, school district, county utility district, sanitary district, metropolitan sewage district, or other public body created by or pursuant to state law) are not required to hold a Wisconsin CDL if they meet all of the following:
