Castaic, CA (March 11, 2026) – Authorities have identified 67-year-old Hahn Truong as the bicyclist who was struck and killed by a bus in the Castaic area.
Incident Details: According to the California Highway Patrol (CHP), the collision occurred around 7:30 a.m. on March 11, 2026, near 32184 Green Hill Drive, west of the Golden State (5) Freeway. Investigators reported that a bicyclist and a Santa Clarita Transit bus were involved in the crash on a residential street.
Emergency responders arrived at the scene and pronounced Truong dead. The bus driver was not injured, and officials reported that one passenger was on board at the time, though that individual left the area before officers arrived.
Investigation: The CHP is continuing to investigate the circumstances surrounding the fatal collision. At this time, officials have not released details about how the crash occurred or what actions led to the collision between the bus and the bicyclist.
Investigators will likely examine several key factors, including:
- Vehicle and bicycle positioning—determining where both the bus and the bicyclist were located on the roadway prior to the collision.
- Driver awareness and visibility—evaluating whether the bus driver had a clear view of the cyclist and whether any obstructions or roadway conditions affected visibility.
- Roadway design and traffic patterns—reviewing the residential street layout, traffic flow, and potential hazards in the area.
- Witness accounts and surveillance footage—gathering statements from nearby residents or reviewing camera footage that may have captured the incident.
- Vehicle data and physical evidence—analyzing impact points, braking evidence, and damage to determine how the crash occurred.
Authorities have indicated that drugs or alcohol do not appear to be factors in the crash. The results of this investigation will help determine whether any traffic laws were violated or whether additional safety measures may be needed in the area.
Legal Considerations: Crashes involving buses and bicyclists often involve heightened legal scrutiny because commercial passenger vehicles must meet strict safety standards. Bus drivers are required to operate their vehicles with a high degree of caution due to the size of the vehicle and the risk it poses to vulnerable road users such as cyclists and pedestrians.
If investigators determine that the bus driver failed to maintain proper awareness, failed to safely share the road with a cyclist, or otherwise acted negligently, Hahn Truong’s surviving family members may have grounds to pursue a wrongful death claim.
Because the vehicle involved was part of a public transit system, the claim could also involve potential liability for the transit agency responsible for the bus’s operation, driver training, and driver supervision.
My thoughts are with the family and loved ones of Hahn Truong as they grieve this tragic loss, and I hope they find comfort and support during this difficult time.
