The white BMW also hit a couple of parked vehicles, as well, around 7:15 a.m., Detective Sgt. James DePreta said.
The two black occupants, who appeared in their early 20s, apparently hitched a ride from the dump truck driver, DePreta said.
PSE&G responded and the highway was eventually reopened.
Anyone who might have seen something or captured video is asked to contact Rochelle Park police: (201) 843-1515.
All calls will be kept confidential.
