Here in Colorado they went to 10 year licenses.
When hubs & I got married in 2003 I had my license changed
to reflect my new last name. Renewed my license last year.
In that 10 year time frame they had changed the way renewals
where being done. As long as you didn't have any tickets or anything
else to cause an issue on your driving record (points etc...) than you
could go online and renew the license you pay for it at that time, about
2-4 weeks later your new license arrives in the mail.
