State police say the driver of a minivan was seriously injured Wednesday night when his vehicle got pinned under a truck on I-95.

The accident happened at about 11:30 p.m. on the southbound side of I-95 near the Nelson Bridge in Harrison. State police say the minivan's driver, a 39-year-old man from upstate, drifted onto the shoulder of the road and slammed into the parked truck, shearing the van's roof off.
