Here's a link to Lexis-Nexis for Colorado Revised Statutes so you can verify it:
http://198.187.128.12/colorado/lpext...s-main.htm&2.0
The site is written in frames, but vehicle code is primarily found in Title 42, Article 4.
Please verify the law before posting that something is illegal.
Also, the annotations are important (and listed in the Lexis-Nexis listings) so please read them too.
