Code	Attribute	Definition
0	Intrastate	This attribute represents a motor carrier that operates entirely within the state and does not have the authority to engage in interstate commerce. Intrastate operators are not required to have a USDOT Number by the Federal Motor Carrier Safety Administration; however, some states do require that certain intrastate operators secure a USDOT Number.
1	Interstate	A commercial vehicle in the United States where the transit between the points of origin and termination does not occur entirely within the borders of the State of origin. A motor carrier that has authority to operate across state lines. Interstate operators are required to have a USDOT Number by the Federal Motor Carrier Administration.
2	Not in Commerce (Other Truck or Bus)	Personal rental vehicles (e.g., U-Haul, Ryder, Penske) that qualify by size (Over 10,000 lbs. GVWR/ GCWR) that are operated by a private individual. In these situations the rental company is not the carrier and should not be recorded.
3	Not in Commerce (Government)	Any government vehicle, whether it is operated by the local, State, or federal government. In most circumstances, the government-owned vehicle will not have a USDOT Number.
4	Other Operation/Not Specified	This attribute is used for a variable that is not addressed by the previous attribute options.  If this attribute is used, an explanation in the narrative is recommended.
