What's the status on having a loaded handgun in your car without a CCL in Denver? Is it something that I shouldn't worry about?

Another thing that I'm unsure of is do we have to tell a LEO that there's a gun in the car if they don't ask? Naturally I'd let them know immediately if they asked or needed to search my car or whatever but I don't see the point if it's just a routine traffic stop or something like that and they don't bother to ask.
