A barrier vehicle is parked ahead of a stationary operation, and provides protection for workzone crews. Is this statement true or false?

The statement is true because a barrier vehicle is specifically designed to enhance safety in work zones by providing physical protection for both the workers and the public. When parked ahead of a stationary operation, the barrier vehicle serves as a shield against oncoming traffic, effectively reducing the likelihood of accidents. Its presence helps to create a buffer zone, allowing workzone crews to perform their tasks with decreased risk from vehicles that may inadvertently enter the work area. This practice aligns with safety protocols that prioritize the protection of personnel in high-risk environments.
