Highway 17 in Jones County was shut down for a couple of hours Tuesday afternoon after a multi-vehicle crash in Pollocksville.
One of the vehicles was an ambulance.
Deputies say a BMW crossed the center line and grazed the ambulance. That caused the JAS ambulance to swerve, hitting an SUV.
Four people in the ambulance were taken to Onslow Memorial Hospital, while three other people injured were transported to CarolinaEast Medical Center.
Traffic was rerouted onto Ten Mile Fork Road and then back onto Highway 17. The busy highway has since reopened.
