Six highway construction workers have been killed in California work zones since Aug. 10, prompting the California Department of Transportation to call for stronger driver awareness and renewed safety measures across the state.
In an Oct. 8 announcement, Caltrans urged motorists to reduce speeds, move over when approaching qualifying stopped vehicles, and avoid distracted or impaired driving near active construction and maintenance sites. Three of the six workers died in a single incident in Riverside County on Sept. 25.
The department emphasized that safer driving practices are essential for protecting construction crews working near moving traffic. Motorists are encouraged to remain alert, follow posted work-zone restrictions and allow crews sufficient space to perform their duties.
Following the Riverside County incident, Caltrans called an immediate safety stand-down and directed construction teams and contracted partners to review roadside safety procedures.
The department is also establishing an executive-level safety committee with industry partners. Its planned work includes examining opportunities to deploy new technologies and safety devices in work zones, assessing existing standards, and reviewing whether Caltrans contracts should require additional safety measures.
These steps could affect how transportation projects address roadside hazards, coordinate safety responsibilities and specify protective measures for workers. The announcement did not provide a timeline for the committee’s recommendations or identify specific contract changes.
Highway construction crews often work close to active traffic, making driver behavior and effective work-zone protections critical parts of project safety. Caltrans’ planned review puts renewed attention on the responsibilities shared by transportation agencies, contractors and motorists.
For contractors working on California transportation projects, the review could lead to further discussion about roadside safety procedures, equipment and contractual requirements. Any new requirements will depend on the department’s subsequent decisions and guidance.
Caltrans also reminded drivers that California’s Move Over law requires motorists to change lanes when approaching qualifying stopped vehicles displaying warning signals, when it is safe to do so, or slow down if moving over is not safe. Drivers should follow applicable signs and speed restrictions through construction zones.
