A Thomaston woman has filed a lawsuit against Regional School Unit 13 for a bus accident that occurred 11 months ago in Warren.

Cheryl A. Weaver is claiming she suffered serious and permanent injuries as a result of the April 27, 2009, incident that occurred on Route 131 in Warren near Stetson Auto.

She claims the crash was due to the negligence of the district, which was then Maine School Administrative District 50. The bus driver was Robert Watts.

According to the Maine State Police in its report last year, the electrical system on the bus died and caused the 2006 bus to lose its power steering. The bus went into a ditch. The incident occurred at 9:30 p.m.

Maine State Police Trooper Jeremiah Wesbrock said at the time two students were taken by ambulance to Penobscot Bay Medical Center in Rockport with minor injuries.

The trooper said bus driver Watts did a good job in handling the bus when its power steering, power brakes and lights went off.

“He did the best job he could,” the trooper said.

When the bus went into the ditch, the front end struck the other side of the ditch, causing about $1,000 worth of damage.

The Maine State Police and the Warren Fire Department and Emergency Medical Services responded to the incident.

The bus carried the Georges Valley High School baseball and softball teams that were returning from games played against Mountain Valley in Rumford.

RSU 13 Superintendent Judy Lucarelli said the claim has been forwarded to the district’s insurance carrier.

Weaver was a parent volunteer on the bus. Her notice of claim sought about $400,000 in damages from the district.
