San Diego police are investigating what caused an 18-year-old man to veer off a Mira Mesa roadway and crash into a light pole Tuesday.
The teenager was in critical condition following the crash at about 8 a.m. near Black Mountain Road and Rockfield Way that left him trapped inside the rolled over Nissan Armada SUV.
San Diego Fire-Rescue crews worked to cut open the vehicle and pull the driver out. He was taken to a nearby hospital.
An SDPD sergeant at the scene told NBC 7 police don't yet know what caused the driver to lose control of the car. There were no obvious skid marks and a witness told police it did not appear the driver was speeding.
A portion of Black Mountain Road was closed during the investigation into the crash but southbound lanes were expected to reopen shortly after 10 a.m.
