The Colorado Department of Transportation (CDOT, pronounced See Dot) is the principal department of the Colorado state government[3] that administers state government transportation responsibilities in the state. CDOT is responsible for maintaining 9,144 mile highway system, including 3,429 bridges with over 28 billion vehicle miles of travel per year. CDOT's Mission is "To provide the best multi-modal transportation system for Colorado that most effectively moves people, goods, and information."[4]

Motor Carriers over 10,000 lbs are regulated by the state and are required to obtain a federal United States Department of Transportation (USDOT) safety tracking number used to monitor carriers' safety management practices and controls.
