Highway case?

Do you have the CRS for that?

Yep.

33-6-125. Possession of a loaded firearm in a motor vehicle

It is unlawful for any person, except a person authorized by law or by the division, to possess or have under his control any firearm, other than a pistol or revolver, in or on any motor vehicle unless the chamber of such firearm is unloaded. Any person in possession or in control of a rifle or shotgun in a motor vehicle shall allow any peace officer, as defined in section 33-1-102 (32), who is empowered and acting under the authority granted in section 33-6-101 to enforce articles 1 to 6 of this title to inspect the chamber of any rifle or shotgun in the motor vehicle. For the purposes of this section, a "muzzle-loader" shall be considered unloaded if it is not primed, and, for such purpose, "primed" means having a percussion cap on the nipple or flint in the striker and powder in the flash pan. Any person who violates this section is guilty of a misdemeanor and, upon conviction thereof, shall be punished by a fine of fifty dollars and an assessment of fifteen license suspension points.

From CRS 33-1-102:

(32) "Peace officer" means a sheriff, undersheriff, deputy sheriff, police officer, Colorado state patrol officer, or town marshal; a district attorney, assistant district attorney, deputy district attorney, or special deputy district attorney; an authorized investigator of a district attorney; an agent of the Colorado bureau of investigation; a Colorado wildlife officer or special wildlife officer; or a parks and recreation officer.

The state patrol page you quoted is really not correct on what 18-12-105 criminalizes and permits. In 18-12-105, it is a defense to the crime of having a concealed weapon on your person that the weapon is being carried for the purposes of personal protection while traveling. CRS 18-12-105(2)'s exception does not override CRS 33-6-125's prohibition.
