According to initial reports, Williams sadly stood little chance against the driver's much larger SUV.

At around 4:53 PM on the day of the accident, Koss was behind the wheel of a Honda Element SUV when he allegedly took a sharp left turn and cut across the northbound lanes on Route 30, in an attempt to turn into an auto shop parking lot.

Williams, who was traveling in the northbound lanes, was left with little to no time to react as the SUV turned into his lane.

The police report stated that "Williams was unable to avoid a collision and was thrown from his motorcycle."

It was noted that Koss was not intoxicated at the time of the collision.

Koss turned himself in to authorities on Tuesday and he was subsequently charged, processed, and released.

Koss was scheduled to appear for arraignment at the Criminal Division of Vermont Superior Court in Bennington on September 25.
