Which of the following is not required to be included in a job briefing for roadway work groups?

Including the pre-determined place of safety (PPS), type of on-track safety, and potential hazards and physical characteristics of the work location in a job briefing for roadway work groups is essential for maintaining safety and situational awareness. The PPS helps ensure that all crew members are aware of where to go in case of an emergency. Understanding the type of on-track safety measures in place is vital for compliance with safety protocols and ensures that all members are on the same page regarding operations. Discussing potential hazards and the physical characteristics of the work location allows team members to evaluate risks and prepare accordingly, enhancing their overall safety.

The aspect not required is the mention of any other jobs currently in progress. While it is valuable to be aware of other activities in the vicinity, it is not mandatory to include this information in every job briefing. Safety protocols primarily focus on the specific job at hand and the related hazards rather than on external work that could be happening in the area. Therefore, option C stands out as non-essential in this specific context.
