Since § 42-3-103 is similar to § 42-3-103 as it existed prior to the 2005 amendment to article 3 of title 42, which resulted in the relocation of provisions, relevant cases construing that provision and its predecessors have been included in the annotations to this section.   The requirements of this section relate to revenue rather than safety, and a violation of its terms by failing to register the motor vehicle does not confer any additional rights upon one who is damaged by its operation unless there is some causal connection between the law violation and the injury of which complaint is made. Carlson v. District Court, 116 Colo. 330 , 180 P.2d 525.   One riding in unregistered automobile is a trespasser. Under this section one riding in an automobile which has not been registered is a trespasser on the streets, and a city owes such a person no duty to keep the streets in a reasonable safe condition. City of La Junta v. Dudley, 82 Colo. 354 , 260 P. 96 (1927).   This article requires that trailer coaches and mobile homes be registered, taxed, and licensed in the same manner as automobiles.

Trucking company was an interstate carrier and was legally accountable for the fees and taxes incurred by such vehicles in Colorado, for purposes of determining whether it could challenge the constitutionality of a statute that increased motor vehicle carrier registration fees, because it was the owner of motor vehicles operated in interstate commerce during the relevant time period, even though it was a lessor and not the actual operator of the trucks in question.
