You do not need a CCW permit to carry a hand gun in your car, and there are no restrictions as to where or how you carry it.

I was recently stopped at a DUI check point and asked to exit my vehicle for a sobriety test while wearing my loaded (with round in the chamber) gun on my hip in an IWB holster, covered under my shirt. I do NOT have a CCW. I explained to the officer that I was carrying. He instructed me to pull over to the side of the road and wait for him there. He approached with another officer, had me undo my seat belt and get out of the vehicle. I put my hands on the roof, and they removed my pistol from the holster under my shirt. The guy started to do the finger sobriety test, then stopped less than 10 seconds later when he realized I was no where near intoxicated. They came to the passenger side of the car, handed me my license, set the now unloaded gun (magazine out and slide locked open) with the mag next to it and even tossed the round I had chambered onto the floor and that was that. They didn't even lecture me about having the gun and the way I was carrying it.

This was in Thornton by the way.
