Section 6(1)(b) and 6(2) of chapter 334 (SB 15-090), Session Laws of Colorado 2015, provides that changes to this section take effect only if the department of revenue receives enough gifts, grants, and donations for materials, start-up costs, and computer programming necessary to implement this act, and take effect January 1, 2016, only if the revisor of statutes receives written notice that such funds were received. The revisor of statutes received the required notice, dated February 12, 2016.     Cross references:   For the penalty for a class B traffic infraction, see § 42-4-1701 (3)(a)(I) .   ANNOTATION   Annotator's note. Since § 42-3-202 is similar to § 42-3-123 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.   Where the suspect's license plate was obstructed by dirt, in violation of this section, the troopers had a reasonable suspicion that criminal activity was occurring. Although after stopping the vehicle, the troopers could see the plates well enough to discern that they were current, the continued obstruction of the plate constituted an ongoing license plate violation and thus a reasonable purpose for the stop. Because the troopers had a reasonable suspicion and a reasonable stop, they properly initiated an investigatory stop. People v. Altman, 938 P.2d 142 (Colo. 1997).   Applied in People v. Clements, 665 P.2d 624 (Colo. 1983).
