SAN DIEGO - The California Highway Patrol is trying to determine if a two-vehicle crash on Interstate 8 in San Diego on Saturday was a case of road rage.
According to the CHP, at about 3:50 p.m., 21-year-old Kelsey Shakespeare was in her silver Volkswagen Jetta and heading west on I-8 just west of College Ave.
At the same time, 33-year-old Stephanie Pontarolo was driving her green Toyota Tacoma on the same stretch of freeway, sister-station KGTV reported.
The CHP says that the two drivers -- for unknown reasons -- "became engaged in an altercation."
Video captured by YouTube user San Diego DashCam shows the Tacoma truck driving next to the Jetta when the truck suddenly careens into the path of the sedan. The Jetta hits the side of the Tacoma, causing it to strike a guardrail and overturn onto the right shoulder of the freeway.
According to the CHP, Pontarolo suffered minor cuts to her face, arm and foot. Shakespeare complained of back pain following the crash.
While the crash is being treated as a traffic collision, CHP officials said they are continuing their investigation.
The CHP says: "... if it is determined through our investigation that there was an intentional act to harm another person this incident would not be treated as a collision and separate charges would follow. The potential charges could range from attempted murder to assault with a deadly weapon depending on the circumstances."
Witnesses say the Tacoma's driver drove up next to the Jetta and flipped the driver off with both hands just before bumping the car.
