Authorities say a couple was traveling on I-540 near Glenwood Avenue just after 10 p.m., when their car was hit by one or two bullets.
Raleigh police said Thursday that Wednesday's shooting may have stemmed from a road rage incident, according to preliminary investigative findings.
However, the victims of Wednesday's shooting say they did nothing to provoke the incident and nothing happened between them and the suspect prior to the shooting.
The driver tells ABC11 that he and his girlfriend had just got onto I-540 at Capital Blvd. when a car started tailgating them and flashing their lights. He said they hadn't been to any parties or bars and didn't get into any arguments with anyone, so the couple pulled over into the right lane to see what the car wanted. However, the car just kept tailgating, following whatever move they did.
The driver says the car, a Dodge Charger, suddenly decided to pass them and then a Silver Acura pulled up and shot at them.
The driver was cut on his arm by glass fragments from when a bullet struck his front driver-side window and exited through the front passenger-side window. His girlfriend riding in the front seat beside him was not hurt.
After the shooting, the pair drove to the Raleigh Durham International Airport for help.
In a 911 call, the couple told the operator that they were scared to stop in Raleigh after the shooting.
"Ok, well, I'm scared to stop, because, I, I, I ... I don't know what to ... we need to find like a safe place to stop!"
Raleigh police are currently looking for an early 2000s model silver Acura with tinted windows and chrome rims.
Police spokesperson Jim Sughrue says no connection has been established between the I-540 shooting and two other highway shootings in Durham over the last week.
The car in the I-540 shooting has similarities to the style and vehicle description from Monday night's shooting on the Durham Freeway at Briggs Avenue.
The victim in that incident was not injured and called police.
However, on Saturday a driver was killed when he was shot while behind the wheel on the Durham Freeway near Fayetteville Street. It is unclear if the same car was involved in that shooting.
