The Federal Motor Carrier Safety Administration (FMCSA) is an agency within the United States Department of Transportation (USDOT). Its primary mission is to reduce crashes, injuries, and fatalities involving large trucks and buses.<ref name="mission">FMCSA: Our Mission</ref>

FMCSA regulates commercial motor vehicle safety in the United States. For highway carriers, FMCSA rules and systems may affect carrier registration, USDOT numbers, operating authority, driver qualifications, hours of service, vehicle maintenance, drug and alcohol requirements, safety ratings, roadside inspections, and enforcement.

Why FMCSA Matters for Cross-Border Carriers

Canadian, Mexican, and U.S. carriers operating commercial motor vehicles in the United States must comply with applicable FMCSA requirements. Common cross-border issues include:

USDOT Number: A USDOT number identifies a motor carrier in FMCSA systems and is used to track safety information, inspections, crashes, and compliance history. Carriers that operate commercial motor vehicles in the United States should confirm whether they need a USDOT number or need to keep an existing registration current.<ref name="registration">FMCSA Registration</ref>
Operating Authority: Some for-hire carriers also need FMCSA operating authority, often called an MC number. Whether operating authority is required depends on the carrier's operation, cargo, and business model. Carriers should confirm their requirements with FMCSA or a qualified compliance advisor.<ref name="registration" />
Driver Licensing: FMCSA states that the only foreign commercial driver licences accepted in the United States are licences issued by Canadian provinces or territories and by the federal government of Mexico. Canadian drivers do not need a U.S. CDL solely because they are operating in the United States, and Mexican commercial drivers must hold a valid Licencia Federal de Conductor rather than a Mexican state-issued licence for U.S. cross-border commercial operations.<ref name="foreign-cdl">FMCSA: Commercial and non-Commercial Driver License Requirements</ref>
Safety Compliance: Carriers and drivers operating in the United States must comply with applicable U.S. safety regulations, including hours of service, driver qualification, inspection, maintenance, and other Federal Motor Carrier Safety Regulations.

FMCSA and BorderConnect

FMCSA information is not the same as customs release information, but it is still important for cross-border highway carriers. Accurate carrier, truck, and driver information helps avoid avoidable compliance or processing problems when preparing ACE eManifests and maintaining BorderConnect profiles.

In BorderConnect workflows, FMCSA-related information may be relevant when maintaining:

company and carrier profile details;
truck and trailer profiles;
driver profiles and licence information;
ACE eManifest carrier information; and
internal compliance checks before a driver is dispatched to the border.

Related FMCSA Systems and Programs

SAFER: The Safety and Fitness Electronic Records (SAFER) system provides company snapshots and safety-related carrier information.
SMS / CSA: The Safety Measurement System (SMS) is part of FMCSA's Compliance, Safety, Accountability (CSA) program and uses inspection, violation, and crash data to help identify carriers for intervention.
Drug and Alcohol Clearinghouse: The FMCSA Clearinghouse is used for drug and alcohol program compliance for CDL and commercial learner's permit drivers subject to the testing rules.
Unified Registration System: The Unified Registration System and FMCSA registration tools are used for registration, updates, and authority-related filings.
