Matt Dillon's year is ending with a pop -- as in popped for going way, way over the speed limit in Vermont.
Law enforcement sources tell us Dillon was pulled over going over 100 MPH on Interstate 91 in rural VT, and had to be arrested because he was going so far over 65. We're told if he'd been doing 80-90, he could've gotten by with just a ticket. Instead, cops hauled him in for a little finger-printing and picture-taking session (see right).
Dillon was charged with excessive speeding and released with a citation.
