A deadly single-car crash on Interstate 280 just north of El Monte Road in Los Altos Hills left one person dead and two others with major injuries yesterday. According to the California Highway Patrol, a Honda Accord crossed the freeway's center median and slammed into a tree. The driver and a front-seat passenger were rushed to Stanford Medical Center with serious injuries, while a rear-seat passenger who was not wearing a seat belt died at the scene.

What officials say

The CHP said the collision was reported at about 7:50 AM and that the Honda traveled through the center median between a metal guardrail and a concrete barrier before hitting the tree. Investigators remained on scene collecting evidence, and officials have not yet released the victims' names. These details come from a California Highway Patrol statement via Bay City News Service, as reported by SFGATE.

Why seat belts matter

The death of the unrestrained back-seat passenger is a stark reminder of how much difference a seat belt can make. The National Highway Traffic Safety Administration reports that buckling up in passenger cars cuts the risk of fatal injury for front-seat occupants by roughly 45 percent, and that seat belts have saved thousands of lives. Those findings are outlined by NHTSA.

Local context

This part of I-280 near the El Monte Road offramp has seen its share of serious wrecks and temporary shutdowns in recent years, fueling local coverage and periodic calls for safety improvements. Earlier reporting by the Mountain View Voice documents previous fatal collisions in the same corridor. Neighbors and traffic-safety advocates have pointed to the freeway's terrain and barrier layout as complicating factors when drivers lose control.

The CHP is still investigating what led up to Monday's crash and has not released any additional information about possible impairment or other contributing factors, according to the agency statement reported by SFGATE. This story will be updated if authorities release more details.
