WESLEY, Maine — A 19-year-old Trescott woman was killed early Thursday morning when her sedan collided with a loaded logging truck on Route 9.

Kayla Robinson was pronounced dead at the scene by medical personnel, according to a news release issued Thursday afternoon by the Washington County sheriff’s office.

Robinson had been driving east toward Calais and “it appears she crossed the center [of the roadway],” striking a logging truck head on at about 5 a.m., the release states. She was ejected from her vehicle.

The driver of the logging truck, Dale Earle, 55, of Calais, was not injured but was taken to Down East Community Hospital in Machias for a blood alcohol content test. Chief Deputy Michael Crabtree of the sheriff’s office said alcohol was not suspected as a factor but that testing was required in fatal motor vehicle crashes.

The passenger had minor injuries and also was taken to DECH for treatment.

The cause of the crash remains under investigation.

Traffic was delayed for several hours as police investigated and crews worked to clear the highway.

Small pieces of wood and tree bark littered the roadway at the scene and the logging truck was on its side. Numerous skid marks were visible along the roadway, which was also littered with debris from the black sedan. The logs had been cleared away by noon.

Crabtree said some motorists experienced delays of up to 40 minutes while crews tried to put the truck back on its wheels.

The road was fully reopened by 3:15 p.m., according to a county dispatcher.

Officials with the sheriff’s office are being assisted in the investigation by officers from the Maine State Police Commercial Enforcement and Accident Reconstruction units, according to the release.

Also responding to the accident were several members of the Wesley Fire Department and Alexander first responders.
