State police say a tractor-trailer may have been following too close Wednesday morning when it collided with a van on Route 3 in China.

Both vehicles were traveling westbound towards Augusta when the van slowed down to make a left-hand turn. The truck swerved and then collided into the side of the van, sending the van into the woods along Route 3. The tractor-trailer overturned in the road, spilling hundreds of sheets of plywood it was hauling.

The driver of the van, Pamela Page, 49, of Palermo, who was taken to MaineGeneral and then transferred to Maine Medical Center in Portland. She was trapped in the Chrysler Town and Country van for almost an hour. Firefighters used extraction equipment to cut the doors off the van and free the woman.

The truck driver, James Butler, 46, of Liberty, was not injured in the crash.

The road was closed for four-and-a-half hours, until 12:30 p.m., when police opened one lane to traffic. As police investigated the accident, crews worked to clean up the crash site, including the removal of the plywood and about 60 gallons of diesel fuel that leaked from the truck's fuel tanks.

No charges were filed, but the district attorney's office will review the crash report from state police to determine if someone will be charged in connection with the accident.
