DARTMOUTH — A Brockton woman and Connecticut man are being treated for serious injuries at Rhode Island Hospital after a crash early Tuesday morning on Interstate 195 in Dartmouth.

Massachusetts State Police say the early morning crash happened in the eastbound lanes of the highway in the area of Exit 12, leading to Faunce Corner Road.

A preliminary investigation by Trooper Adam Rego indicates that at about 2:30 a.m., a 41-year-old man from Stratford, Connecticut was traveling on I-195 East in a 2009 Mitsubishi Eclipse at a high rate of speed.  The man lost control of the car, causing it to crash into the guardrail.  The impact caused the man to be ejected from the vehicle.  He and his passenger, a 24-year-old Brockton woman, were transported to Rhode Island Hospital for treatment of serious injuries.  No one in the Dodge was injured in the crash.

A 2004 Dodge Ram, which was traveling eastbound in that area, made slight contact with the Mitsubishi as it maneuvered to avoid a collision.

The crash and emergency response also held up morning rush hour traffic for hours.

This crash remains under investigation with assistance from the State Police Collision Analysis and Reconstruction Section, Crime Scene Services Section, and troopers assigned to the Bristol County District Attorney’s Office.  No charges have been filed at this time.

State Police were assisted on scene by Dartmouth Fire and EMS and Dartmouth Police.
