Tractor Trailer Unit crash, Interstate 95 NB, Portsmouth, NH

On Friday October 4, 2019 at approximately 5:22 am, New Hampshire State Police, Troop-A received a call of a commercial motor vehicle crash on I-95 northbound, at the exit 3 off ramp in the city of Portsmouth. Troopers from the Troop-A barracks responded to the area and located a tractor trailer unit, at final rest in the wood line adjacent to the exit 3 off-ramp. Initial investigation revealed that the driver of the 2019 Kenworth truck had fallen asleep, which resulted in a failure to negotiate the off-ramp. The driver subsequently drove off the roadway, down the embankment, and into the wood line.

The driver, Sterling Wallace, age 46, of Philadelphia, Pennsylvania was not injured. The right hand travel lane was closed for approximately 3 hours to remove the vehicle and trailer. This lane closure had little impact with morning commuter traffic.

NH State Police personnel were assisted at the scene by NH DOT and National Wrecker.

Anyone with information pertaining to this incident is asked to contact Sergeant Thomas Conlon, NH State Police-Troop A at (603) 223-8490, or via email at
