California’s basic speed law and following-distance requirements are designed to prevent exactly these types of crashes.- Vehicle condition: Brake functionality, tire condition, lighting, and overall maintenance history. Commercial operators are required to keep their vehicles in safe working order and document inspections.- Hours-of-service compliance: Whether the driver was operating within federal and state limits on driving time and rest breaks to reduce fatigue.- Electronic data: Many trucks carry electronic control modules (ECMs) or telematics systems that record speed, braking, throttle, and other events before impact. Surveillance footage, dashcam video, and traffic signal timing data can also be critical.- Roadway environment: Visibility at the intersection, traffic signal operation, weather, and any potential roadway hazards. In some cases, issues with intersection design or signage may be evaluated.Authorities often conduct a multi-week or multi-month investigation before issuing a final report. Families should obtain a copy of the collision report as soon as it becomes available to better understand findings and next steps.Rear-End Crashes and Liability in CaliforniaRear-end collisions at traffic signals are among the most common—and preventable—crashes. Under California law, drivers must maintain a safe speed and sufficient following distance to stop when traffic ahead is stopped or slowing. While each crash must be evaluated on its own facts, a driver who strikes a stopped vehicle from behind is frequently found at fault for failing to maintain control or to keep a proper lookout.
