Biggest issue around here is vehicles with an expired registration. Can't drive anywhere without seeing vehicles with expired tags dating back upwards of two years or more.
As of Jan.01,2023 all new vehicle registrations required a new plate being issued. You can no longer transfer the old plates to the new vehicle. Now you'll see temp tags that have long expired.
Two Counties said that enforcement of expired tags would be dealt with by LE but apparently that isn't happening unless one is pulled over for another offense. With your mindset

eek

we could set up a checkpoint similar to a DUI and pull people over all day.
We also can't forget those that move here from out of State that wont register their vehicle in Colorado within 60days because their current registration is still good for another year or so.
