October Vehicle Registration Renewals Alert: If your vehicle registration is up for Oct renewal, the postcard will say proof of insurance required. For 99% of residents, it is not. We have it in our records. Try to renew online or other method first as you should be fine if nothing has changed with your car insurance. See the Colorado Dept of Motor Vehicle statement for more information.
