While none of us are above directing the occasional flash of anger towards fellow drivers on the road, this recent incident in California could potentially be taking road rage to a whole other level.

Two San Diego women are under investigation after road rage has been cited as a possible cause for a motorway crash.

Kelsey Shakespeare, 21, was driving a silver Jetta and Stephanie Pontarolo, 33, was driving a green Tacoma pickup, when their two vehicles crashed at around 4pm on Saturday. The two drivers got involved in an altercation of some sort, according to California High Patrol Officer Jake Sanchez.

The Tacoma pulled alongside the Jetta and veered to the right, hitting the Jetta, Sanchez said. Both vehicles crashed off the freeway onto the right shoulder, and the Tacoma overturned on its side.

Pontarolo suffered minor cuts and scrapes to her face, arm and foot, while Shakespeare complained of back pain, Sanchez said.

Investigators were trying to determine the nature of the altercation that preceded the crash. They have initially classified the crash as an accidental collision, but if they determine that the pickup driver intended to harm the driver of the Jetta, charges could range from attempted murder to assault with a deadly weapon, Sanchez said.

The crash was captured on the dash camera of a car that was following the two vehicles. The video, which was posted on YouTube, shows the pickup following the Jetta. It then moves into the lane to the right of the Jetta, pulls ahead and abruptly veers to the right, striking the front of the Jetta. Both cars go out of control and crash on the side of the motorway.
