Mechanically and electrically operated gates restricting vehicle entrance and exits at all facilities will be operated only under one of the following conditions:
- The gate operator has direct visual control of the gate by means of a TV monitor or by placing himself in a position to see that the gate has no obstructions when being opened or closed.
- The gate operator is being directed by a member of the vehicle crew by means of voice communication or visual signal.
If there is doubt, do not operate the gate until it is determined that the gate can safely be opened or closed.
