Which of the following is true about roadway boundaries?

The correct answer highlights that roadway boundaries include all areas between the roadway fences at grade tracks. This is significant in Roadway Worker Protection training, as understanding the extent of roadway boundaries is crucial for ensuring the safety of worker operations in proximity to active tracks. The delineation provided by roadway fences is essential to delineate safe working zones from places where trains operate, particularly at grade crossings where risks may be heightened.

Recognizing the area encompassed by fences helps in identifying where workers can safely conduct operations and where they must exercise extra caution. Knowing that boundaries extend to these fenced areas ensures workers are aware of the limits and can maintain safe distances from track zones.

Other options include inaccuracies that may lead to misunderstanding. For instance, some may assume that roadway boundaries are the same across all rail systems, but this concept can vary depending on specific regulations and practices of different rail operators. Additionally, boundaries can indeed extend between walls and railings in tunnels where applicable safety precautions are in place, rather than excluding those areas completely. Furthermore, the idea that all non-track areas are excluded from boundaries is misleading, as other considerations may define the boundaries' limits. Therefore, understanding that roadway boundaries involve all areas between fences is critical for roadway worker safety.
