CHP Officer Killed in Highway 99 Semi-Truck Crash
CHP officer killed in Highway 99 crash with semi-truck near Tipton
California Highway Patrol Officer Brian Liles was killed Monday evening after his department-issued motorcycle collided with a truck-tractor on northbound State Route 99 near Tipton, authorities said.
The crash occurred at approximately 5:11 p.m. near the Highway 190 interchange, south of Avenue 152, in Tulare County. According to the CHP, Liles was on duty and riding northbound when his motorcycle struck the tractor-trailer. The collision ejected him from the motorcycle, after which he was struck by another passing vehicle, according to information released by the agency.
Emergency responders performed lifesaving measures at the scene, but Liles died from his injuries. He was 44 years old.
Authorities have not released the identity of the truck driver or the motor carrier involved. They also have not announced whether any citations were issued or provided additional information about what led to the initial collision. The investigation remains ongoing.
Liles’ death marked the first California Highway Patrol line-of-duty fatality since 2020, according to the governor’s office. He had served with the CHP for more than 16 years after graduating from the CHP Academy in 2010.
His career included assignments in San Jose, Hayward and Fresno. Liles transferred to the Visalia area in 2019. In December 2025, he became part of the first group of motorcycle officers assigned to the Visalia office after completing specialized training.
Gov. Gavin Newsom expressed condolences to Liles’ family, friends and colleagues in a statement issued after the crash.
“Officer Brian Liles dedicated his life to serving our communities, and his passing is a heartbreaking loss for the California Highway Patrol and the entire state of California,” Newsom said. “He will be remembered for his dedication to serving and protecting the people of California.”
State officials ordered flags at the state Capitol and Capitol Annex Swing Space to be flown at half-staff in Liles’ honor.
Liles is survived by his wife, two children, his parents and two sisters. The CHP 11-99 Foundation, which provides assistance to CHP employees and their families, announced $50,000 in emergency and death benefits for his wife.
CHP personnel later gathered at the agency’s academy in West Sacramento for a Bell Toll Tribute. Commissioner Sean Duryee and Chief Mike Lehman spoke at the ceremony, which was attended by Liles’ family, friends, professional staff members and other law enforcement personnel. The memorial bell is used to honor officers who die while serving California communities.
A major freight corridor
The crash occurred on one of California’s most important north-south transportation routes. State Route 99 runs through the Central Valley, connecting major agricultural, manufacturing and population centers from the Bakersfield area north toward Sacramento.
The highway carries substantial commercial traffic, including truck-tractor combinations hauling produce, packaged goods, industrial materials and other freight. In the Tipton area, commercial vehicles share the roadway with commuters, agricultural traffic, emergency responders and passenger vehicles traveling between Central Valley communities.
For professional drivers, the collision underscores the hazards that can develop when motorcycles, passenger vehicles and large trucks operate in close proximity on a busy freight route. A motorcycle can be difficult to see in mirrors and blind spots, while a collision involving a tractor-trailer can quickly create additional hazards for nearby traffic.
The CHP has not said whether traffic congestion, lane movement, visibility or another condition contributed to the crash. Until investigators release more information, the circumstances surrounding the initial impact remain undetermined.
Investigators also have not said whether the passing vehicle that struck Liles after the first collision was able to stop at the scene or whether its driver suffered injuries. Additional details are expected as the investigation continues.
The CHP’s loss comes after years without a line-of-duty death in the agency. Liles’ colleagues described his service as a commitment to protecting California communities, while state officials and law enforcement personnel gathered to recognize his work and mourn his death.
