Matt Dillon Won't Cop to Speeding

Matt Dillon says he didn't do it!

On Wednesday, the actor entered a not guilty plea to a charge of careless and negligent operation of a vehicle stemming from his Dec. 30 speed-related bust in Vermont.

E! Online is reporting the actor's attorney, Mark Kaplan, entered the plea on the absent actor's behalf during this morning's roughly two-minute hearing.

Dillon, 44, was hit with the speeding charge last month after police clocked him driving at 106 mph in a 65 mph zone.

The police report says the actor was cited as saying, "I screwed up, I know, I know."

If convicted, Dillon could face up to one year behind bars and face a fine of $1,000.
