Two people were injured early Wednesday in a head‑on crash on Lakeville Highway, the CHP said.

CHP officials said they’re still investigating what caused Salvador Becerra‑Vallejo, 31, to veer his northbound Toyota Tacoma into the southbound lane, sideswiping a empty tanker before colliding head-on with a Lexus sedan.

The 7:10 a.m. crash blocked part of the busy two‑lane highway for more than two hours. Northbound traffic diverted onto Old Lakeville No. 3 Road.

Becerra‑Vallejo suffered major injuries and was taken by ambulance to Napa’s Queen of the Valley Medical Center. Lexus driver Claire Wieszcyk, 32, of Petaluma, was taken to Santa Rosa Memorial Hospital with minor injuries.

A Windsor driver headed to work at the time said the Tacoma’s tire blew out and the truck nearly hit his pickup before striking another vehicle behind him.

“He missed me by about two inches,” Stanley Meyers said, who was traveling southbound. “The front tire exploded on the driver’s side and pieces started flying everywhere.”

About 90 minutes after the crash the near-miss stayed with him. “My heart is still racing,” Meyers said.

Firefighters extricated at least one person from the wreckage, according to initial reports. Cal Fire, Lakeville and Petaluma firefighters also responded to the crash.
