Licensing and Permitting Bureau

Dan Kiely The LPB delivers a variety of services to the commercial motor carrier industry that are required by the industry in order to operate legally in the State of Montana. These services include the registration, in accordance with the International Registration Plan (IRP) and the International Fuel Tax Agreement (IFTA), of all commercial vehicles owned by Montana-based carriers and used in interstate commerce; permit services for all carriers who wish to travel on Montana's highways but whose vehicles are size and/or weight noncompliant; specialty customer service packages developed for Montana's commercial vehicle and car rental fleets under the LPB Fleet Vehicle Registration Program; and development and implementation of the State of Montana's commercial vehicle registration, licensing and permitting policies and procedures which are used by both the LPB and the commercial motor carrier industry to assure that a uniform and consistent service relationship is maintained. Additionally, the LPB is responsible in Montana for the Unified Carrier Registration (UCR) program requires individuals and companies that operate commercial motor vehicles in interstate or international commerce to register their business with Montana and pay an annual fee based on the size of their fleet; the International Registration Plan (IRP) which requires that member jurisdictions operate under uniform commercial vehicle registration and licensing procedures; and the Heavy Vehicle Use Tax (HVUT) program whereby Montana-based carriers are monitored and certified compliant by the state with Federal commercial vehicle weight tax requirements. The LPB generates revenue in excess of $29 million each year, which is deposited into the Highway Special Revenue Account.

Operations Bureau

Dennis Hult The Operations Bureau manages Montana's MCSAP, ITS/CVO and CVISN programs; oversees, coordinates and maintains the development, deployment and maintenance of the Division's information technology and other high technology infrastructure; provides statewide MCS purchasing, contract development, and financial, revenue and budget support; collects, analyses and reports data and information regarding the division's activities to support management of MCS; and, manages participation in any MDT, regional, national or international projects involving MCS.

The Operations Bureau is responsible for developing the annual MCSAP Commercial Vehicle Safety Plan and certification documentation, including the program's budget, and delivering the program in order to meet the MCSAP requirements as required under Code of Federal Regulations (CFR), Title 49. Execution and delivering of an acceptable MCSAP program is required in order for Montana to maintain eligibility for full highway construction funding. The Operations Bureau is responsible for collecting, assimilating, analyzing and reporting of data, information and statistics required by the Federal Highway's Administration (FHWA) for Montana's Commercial Vehicle Size and Weight Enforcement Plan and Certification. Like the MCSAP program, Montana's Commercial Vehicle Size and Weight program requires certification, in this case by FHWA to be eligible for full construction funds.
