What should a driver do if they observe a signal indicating a full clear after an advisory speed sign?

When a driver observes a signal indicating a full clear following an advisory speed sign, the appropriate action is to resume normal track speed for their train. This is because a full clear signal indicates that the track ahead is clear for safe travel at the normal maximum speed. The advisory speed sign is generally intended to advise caution and guide the driver to reduce speed under certain conditions, such as poor track or weather conditions. Once the full clear signal is presented, it supersedes the advisory speed, allowing the driver to safely return to normal operations.

Resuming normal speed is essential for maintaining the timetable and operational efficiency, as well as for the safety of the train and its passengers. Proper adherence to signal indications is crucial in rail operations, ensuring that drivers make informed and safe decisions based on current track conditions.
