Who Writes the Tickets in Thornton
The Adams County Sheriff's Office and the agency that reports for Thornton (filed by the FBI as Thornton Police Department) write the traffic tickets in and around Thornton.
The FBI's agency list also places one more agency in Adams County: the University of Colorado at Denver (campus police).
The Arvada Police Department and the Aurora Police Department are each listed by the FBI across several counties including Adams County, so their arrests are not broken out for Adams County here.
The Driving Record and the Colorado Division of Motor Vehicles
The driving record is a separate document from the court file. It is kept by the Colorado Division of Motor Vehicles, which adds each conviction the court reports and handles suspensions; the court does not issue driving records.
Paying a ticket is a conviction, reported to the Colorado Division of Motor Vehicles like any other; contesting it means a plea of not guilty entered with the court by the date on the ticket.
A DUI is a criminal charge rather than a ticket, with its own license case before the Division of Motor Vehicles (see Thornton DUI).
