The driver suffered minor injuries, state police at Perryville said.

The incident closed all westbound lanes briefly, the New Jersey Department of Transportation said; all but the right lane had reopened as of about 7:25 p.m.
Because of an electrical pole damaged in the crash, an acceleration lane to the far right of the westbound highway was expected to remain closed for several more hours, police said. The closure was not anticipated to affect traffic.
The names of the vehicle's occupants were not immediately available.
