Napa Co., CA (May 14, 2026) – A motorcycle passenger died after being thrown from the bike and struck by another vehicle on Tuesday, May 12, on Highway 12 near its intersection with Highway 29. The crash was reported to authorities at approximately 1:52 p.m.
The motorcycle was traveling eastbound between lanes of traffic when it collided with a black Honda. The impact ejected the passenger, who was then hit by a passing car and suffered fatal injuries.

The roadway was closed for roughly 90 minutes following the crash. The incident remains under investigation. We extend our sincere condolences to the family and loved ones of the passenger who lost their life.
What Factors Make Lane-Splitting Crashes Especially Dangerous on California Highways?
Lane-splitting — riding a motorcycle between lanes of moving or stopped traffic — is legal in California, but it carries serious risks, particularly at higher speeds. When a motorcycle moves between lanes, other drivers may not anticipate its presence, leaving little time for anyone to react if something goes wrong. The narrow space between vehicles also limits a rider’s ability to avoid a collision.
Passengers on motorcycles have even less protection than the rider in these situations. They have no controls, no brakes, and no way to brace for a crash. If a passenger is ejected, the risk of being struck by nearby traffic is severe, especially on a busy highway where vehicles are moving at speed.
