A motorcyclist was killed after crossing into the opposite lane and slamming head-on into an SUV on North Vasco Road in unincorporated Livermore on Sunday night, according to the California Highway Patrol.
The deceased rider was identified as Dr. Gilbert Chang, 48, of Brentwood, according to the CHP.
Chang was a well-regarded cardiologist in the East Bay affiliated with several hospitals including John Muir Walnut Creek, John Muir Concord, Sutter Antioch and North Bay Fairfield.
The Livermore man who was driving the SUV, which was traveling in its correct southbound lane, was under investigation for allegedly being under the influence of alcohol, but it appears the CHP will not be pursuing charges in light of the at-fault motorcyclist dying.
The collision occurred just after 9 p.m. Sunday on North Vasco Road north of the city limits in unincorporated Livermore just south of the access road to the Republic Services Vasco Road Landfill, according to the CHP.
Chang was riding a red 2018 Ducati motorcycle northbound on North Vasco Road at an undetermined speed when, for unknown reasons, he allowed the motorcycle to cross the double-yellow lines and move into the southbound lane, the CHP said.
The motorcycle then slammed into the front of an oncoming silver 2002 Chevrolet Trailblazer, which was traveling in the southbound lane at an unknown speed, according to the CHP.
"The motorcyclist was ejected from the Ducati and struck the windshield of the Chevy. The motorcyclist then collided with the roadway, where he came to rest," CHP officials reported.
Chang was pronounced dead at the scene by Livermore-Pleasanton Fire Department personnel at 9:24 p.m.
The Trailblazer driver, identified as 34-year-old Dustin Holland of Livermore, sustained major injuries and was transported by Falck Paramedics ambulance to Eden Medical Center in Castro Valley for treatment, according to the CHP.
Holland was initially placed under arrest on suspicion of misdemeanor DUI, but CHP officials said Monday that "due to the driver of the motorcycle being deceased, there are no pending charges."
North Vasco Road was closed for multiple hours through the crash area due to the investigation and cleanup.
The initial reports on the CHP Incident webpage indicated three or four vehicles were involved in the fatal collision, but CHP officials confirmed Monday it was only the motorcycle and SUV.
Chang's death was one of two fatal crashes in Livermore on Sunday. A wrong-way driver was killed after colliding head-on with an oncoming vehicle on Interstate 580 around 6:30 a.m. that morning.
