A 20-year-old man was killed early Thursday after his car struck a pole in a single-vehicle crash in Clairemont Mesa, according to authorities.
The crash was reported just after 6 a.m. on the northbound lanes of Interstate 805 near Balboa Avenue, according to the California Highway Patrol.
A maroon-colored Acura had been swerving in and out of lanes at a high rate of speed when the driver appeared to lose control of the vehicle upon trying to exit the freeway. The vehicle struck a pole and rolled down an embankment before coming to a halt.
The crash caused four lanes on I-805 northbound to shut down as authorities investigate the scene. I-805 northbound to State Route 163 was also shut down while investigators respond to the incident.
The driver, who was only identified as a 20-year-old San Diego man, died at the scene. The San Diego County Medical Examiner is awaiting results to determine of drugs and/or alcohol were a factor in the crash.
The investigation is ongoing.
