A northbound pickup truck crossed into the southbound lanes just past the end of the median wall.

LOS GATOS — One person was killed and four others were injured in a violent multiple-vehicle collision Monday night on Highway 17, according to the California Highway Patrol.

The crash occurred at about 6:07 p.m. just south of The Cats Restaurant & Bar in Los Gatos, where a gap in the concrete wall that divides the northbound and southbound lanes allows northbound drivers to turn left but also creates a potential traffic safety hazard.

Armond Cobb, 44, of Pinole, was driving a 2016 Ford F-550 northbound when he changed from the right lane to the left lane and hit the wall, according to the CHP. He lost control of the truck, veering to the right, then sharply to the left and through the gap into oncoming traffic.

The Ford collided with the driver’s side of a 2008 Toyota Tacoma and then head-on with a 2007 Toyota Camry in the left lane of southbound Highway 17, according to the CHP.

Cobb’s truck continued into the right lane and slammed into a 2014 Kia sedan hard enough to tear open its roof and eject its driver, according to the CHP. The Ford finally overturned, rolled onto its roof and came to a rest on the shoulder of the highway.

The driver of the Kia was pronounced dead at the scene. The Santa Clara County Medical Examiner-Coroner’s Office has yet to identify her, but the CHP said she was a 19-year-old resident of San Jose.

Cobb, the 25-year-old driver of the Camry and a 19-year-old passenger in the Kia were transported to area hospitals, where they were treated for minor injuries and released, according to the CHP. The 63-year-old driver of the Tacoma sought his own aid.

The CHP said alcohol and drugs appear do not appear to have been factors in the crash.

The collision, which happened in the midst of the evening commute, closed one northbound lane and both southbound lanes until about 11:20 p.m., according to the CHP.

Efforts are underway to improve safety on Highway 17, which saw a 13-year high 938 collisions in 2016. They include assigning more officers to patrol the treacherous thoroughfare and eventually banning left turns like the one at The Cats. The CHP has pointed to increased traffic and people on cellphones as major contributors to the spike in crashes.

Monday night’s collision remains under investigation and anyone with information can contact the CHP San Jose area field office at 408-467-5400.
