Which tool is specifically mentioned for tracking loads?

The correct choice for the tool specifically mentioned for tracking loads is the Yard Management System. This system is designed to help manage and track the movement of trailers and containers within a yard or warehouse environment. It allows for real-time tracking of loads, providing crucial information about the location and status of freight as it moves through the yard.

Using a Yard Management System enables enhanced visibility and efficiency in operations, as it coordinates the flow of goods and helps streamline processes. This is particularly important in busy environments where accurate tracking can significantly reduce delays and improve overall operational performance.

While other tools like FMC, GPS, and PMT may relate to broader logistical or management tasks, Yard Management Systems are explicitly tailored to the needs of tracking loads in yard operations. This specificity makes it the most suitable choice for the question.
