DALLAS (CBSDFW.COM) - A driver ran into the squad car of an off-duty Dallas police officer early Monday morning, along Interstate-35 in Oak Cliff.

The crash happened around 3:30 a.m. in the northbound lanes of the highway near Marsalis Avenue, not far from the the Dallas Zoo.

Officials say the officer, who was working at a construction site on the freeway at the time, is going to be fine. But an ambulance was called to the scene as a precaution.

Video from a Texas Department of Transportation (TxDOT) camera showed that it was a pickup that ran into the rear-end of the squad car.

Both vehicles had to be towed from the scene.
