A Waterville man with two prior drunken driving convictions on his record was charged with operating under the influence Monday night after the Jeep he was driving ran into the back of a tractor-trailer in Kingfield, the Franklin County Sheriff’s Office said.

Jeb Mansfield, 33, of Waterville, was driving a 2001 Jeep when it struck the rear of a tractor-trailer truck making a left turn on Lexington Road in Kingfield, according to a news release from Sheriff Scott Nichols.

Alain Chouinard, 38, of Mont-Laurier, Quebec, was driving the tractor-trailer.

Both Mansfield and his passenger were treated at the scene by Northstar EMS.

Mansfield, who was driving with a conditional license for operating under the influence, was arrested on a charge of operating under the influence and taken to Franklin County Jail. Mansfield has prior operating under the influence convictions, according to Nichols.

A conditional license is granted in some drunken driving cases and provides that the license holder may not consume alcohol before driving and can be suspended for a year if a blood test reveals consumption of any amount of alcohol.

According to an analysis by the Portland Press Herald, from 2003 to 2013 there were 41,134 drivers convicted once of OUI in Maine, 5,628 convicted twice and 720 convicted three times.
