WisDOT's Motor Carrier Services Section (MCSS) regulates interstate trucking and permits for oversize/overweight vehicles. The specific credentials created and maintained by MCSS are:
Registration of heavy vehicles in interstate operation, known as
IRP - International Registration Plan.
Collection and disbursement of fuel tax for heavy vehicles in interstate operation, known as the IFTA – International Fuel Tax
Motor carrier authority, the fundamental credential authorizing operation as a for-hire motor
Notification to carriers to file Uniform Carrier Registration
UCR Program requires all individuals and companies that operate
commercial motor vehicles in interstate or international
commerce to register their business under the UCR program and
pay an annual fee based on the size of their fleet.
Oversize/overweight vehicle permits.
Motor carrier permits and economic development
This program supports economic development because it operates from a fundamental philosophy that fulfillment of regulatory responsibility does not imply or require an adversary relationship. The realization of this
philosophy has been best expressed by substantial commitment of resources to technology development.
