Which of the following correctly defines 'working limits'?

Answer: B — A segment of track with defined boundaries

The term "working limits" is defined as a segment of track with defined boundaries where specific work can be performed safely. This definition is crucial for roadway worker protection as it establishes a clear area in which workers can operate without the worry of being affected by trains or other rail operations. It encompasses the space that has been designated and controlled for the performance of work tasks, ensuring that safety protocols are in place. By defining these boundaries, it helps ensure that the workers are aware of their designated area and that proper warnings and protections are in place to prevent accidents. The precision of this definition is essential in maintaining safety standards and effective communication among crew members and coordinators.
