Which of the following items is NOT checked for hazards on a travel route?

Soil moisture content is not typically checked for hazards on a travel route. The primary concerns when assessing hazards include ensuring that the route is clear of any underground services, personnel, and any plant or equipment that might obstruct safe passage. Checking for underground services is crucial to avoid accidental damage to utilities, while personnel must be monitored to ensure their safety around moving machinery. Plant and equipment need to be accounted for to establish a clear and safe path.

Soil moisture content, while important for understanding ground stability and the potential risk of slipping or getting bogged down, is not a direct hazard when considering the immediate safety of a travel route. It is more relevant in discussions about general site safety rather than specific travel route assessments.
