This reckless and dangerous manoeuvre resulted in a catastrophic multi-vehicle crash involving at least four vehicles, including a Honda and a Toyota Prius. Witnesses at the scene reported seeing a white sedan collide with a silver minivan and the other two vehicles.
The impact caused at least one vehicle to burst into flames, further intensifying the destruction.
Emergency responders were quick to arrive at the scene, but the extent of the damage was severe. Two vehicles were mangled beyond recognition, and debris littered the freeway, making it difficult for rescuers to navigate the wreckage.
Paramedics rushed three individuals to a nearby hospital for treatment of their injuries. Tragically, two victims succumbed to their injuries at the scene.
Among the deceased was William Yost, a 31-year-old resident of Altadena. Yost was identified as one of the victims following the crash. Originally from Pasadena, he had deep roots in the community, having graduated from Pasadena High School in 2011. At the school, he played varsity baseball, a passion that left a lasting impression on those who knew him.

Though tragically cut short, Yost’s life was marked by his humble and self-deprecating sense of humour. In a Facebook bio that surfaced following the incident, he described himself as, “just a guy like any other guy, but I am about twice as stupid.”
The simplicity of this statement belied the affection and warmth that friends and family held for him. Beyond his brief online presence, little information about Yost’s life is publicly available, but his untimely death has undoubtedly left a void in the hearts of those who knew him.
The identity of the second victim has not yet been released, pending notification of next of kin. Authorities are continuing their investigation into the crash, working to piece together the sequence of events that led to the tragedy.
The condition and identity of the wrong-way driver, as well as whether drugs or alcohol played a role, remain under investigation by the CHP.

For the local community, the news of the crash has brought shock and sorrow. The 134 Freeway, a major thoroughfare in the region, was closed for several hours as authorities cleared the wreckage and conducted their investigation. Traffic delays stretched for miles, but the inconvenience paled in comparison to the gravity of the loss.
The incident serves as a sombre reminder of the dangers posed by wrong-way driving, a perilous behaviour that has been responsible for numerous fatalities on California’s highways.
Experts emphasize the importance of staying alert, adhering to road signs, and exercising caution, particularly near freeway ramps where wrong-way drivers are most likely to enter.
As friends and family of William Yost and the unidentified victim mourn their loss, the community is left grappling with the sudden and senseless nature of the tragedy. Tributes and condolences have begun to pour in on social media, with many expressing shock at the loss of a life taken far too soon. Yost’s former classmates and teammates from Pasadena High School have shared memories of his kindhearted nature and his enthusiasm for baseball.
While the pain of this loss is immeasurable, it has also prompted calls for improved safety measures on the state’s highways. Suggestions range from enhanced signage and lighting near off-ramps to the installation of spike strips or other deterrents to prevent wrong-way entry.

Although such measures cannot undo the damage already done, they may help to prevent similar tragedies in the future.
For now, the focus remains on supporting the victims and their families, as well as ensuring a thorough investigation to determine the causes and circumstances of this heartbreaking crash.
