American actor Treat Williams, 71, has died following a traffic accident. The British newspaper "Daily Mail" reported that Williams, who was previously nominated for a Golden Globe, passed away last night when a Honda driver attempted to enter a parking lot and collided with Williams, who was riding his motorcycle in the opposite direction. Williams, known for his roles in the series "Everwood" and "Hair," had been spending the weekend at his home in Vermont just hours before the accident occurred. Police confirmed that Williams was wearing a helmet at the time of the incident. It is noted that Williams was married to actress Pam Van Sant, and they have a son and a daughter.
