Motor Carrier Services

The Motor Carrier Services Division (MCS) of the Montana Department of Transportation protects government investment in Montana's highway system and ensures the safety of the traveling public through uniform regulation of the commercial motor carrier industry.

MCS officers enforce all state and federal commercial motor carrier laws, rules, and regulations. MCS is also responsible for the state's oversize/overweight permit program. MCS administers all policies and rules governing the issuance of oversize/overweight permits and manages Montana's automated web-based permitting system.

Motor Carrier Safety Assistance Program

The Motor Carrier Safety Assistance Program (MCSAP) is a federal grant program that provides financial assistance to states to reduce the number and severity of crashes and hazardous materials incidents involving commercial motor vehicles (CMV).

The goal of the MCSAP is to reduce CMV-involved crashes, fatalities, and injuries through consistent, uniform, and effective CMV safety programs.

Investing grant monies in appropriate safety programs increases the likelihood that safety defects, driver deficiencies, and unsafe motor carrier practices are detected and corrected before they become contributing factors to crashes.
