What is the primary factor evaluated during a DOT compliance review?

The primary factor evaluated during a DOT compliance review is the safety performance of the motor carrier. This focus stems from the Department of Transportation's mission to ensure safe and efficient transportation systems in the United States, which includes monitoring the performance of commercial motor vehicles and their operators.

During a compliance review, investigators assess factors like adherence to safety regulations, accident records, vehicle maintenance practices, driver qualifications, and hours of service compliance. The overarching goal is to minimize risks associated with transportation and safeguard public safety. This evaluation ensures that motor carriers meet established safety standards, ultimately aiming to reduce accidents, enhance driver safety, and improve overall road safety.

While financial stability, environmental impact, and delivery efficiency are important aspects of a motor carrier's operation, they do not take precedence over safety concerns during compliance reviews. Safety performance stands as the foundational element in assessing whether a carrier operates responsibly and in compliance with federal regulations.
