OK, more information about Colorado:

Inspections are annual. Inspection documentation must be presented in person to /get plates. Plates are sold by county DMV locations. To get a drivers license, you have to go to a different location (PITA )

I use CarTech, 1730 W Mississippi Ave, Denver 80223. Small shop, yellow building. Out of state truck must get a VIN verification. CarTech does this, too. Emission cost $55 and VIN verification $20.

One final thing. As far as I know, CO does not check for factory installed emissions equipment...at least CarTech doesnt.

Hi: I am new to this forum but am a non Ford diesel owner (for now). I saw your post about Colorado emissions inspection. Here is some info from the CO DMV:

Diesel Opacity Test
Vehicles that run on diesel fuel will be given a diesel opacity test.

Whether you are required to get a Colorado emissions test depends on where you live. If you either reside or work in the emissions testing area, your vehicle will need to be inspected. Some counties require testing throughout the entire county, while others only require it in parts of the county.
Emissions testing throughout the entire county:

Boulder
Broomfield
Denver
Jefferson

Counties that only require emissions testing in certain parts of the county are:

Adams
Arapahoe
Larimer
Weld
El Paso County requires ONLY diesel inspections and those are limited to certain parts of the county.



Hope this helps

Thanks, Nathan.

Truck puked a little bit too ....It was about a quart high so I drew it down and made another pass and it was ok. We'll see Saturday if it really is or not.

Missed that damned pin by .001 tonight.

It's about time you showed up
