For movement of vehicles and personnel, what does a steady signal mean?

A steady signal indicates that vehicles and personnel are cleared to cross. This signal provides clear authorization for movement, ensuring that those receiving the signal understand they can proceed without hesitation. In the context of air traffic control, a steady signal typically means that the path is safe and free from conflict, allowing for smooth and efficient operations. It is vital in avoiding potential accidents or miscommunications on the ground, as it conveys important information needed to maintain safe practices around aircraft and airport operations.

Other options provide different instructions that could lead to confusion if misinterpreted in this context. For example, a signal indicating "proceed with caution" would imply the need for awareness of potential hazards, while a "stop" signal would clearly indicate an immediate halt, which is not the case when a steady signal is present.
