What action should you take if a track authority has expired?

• A. Continue at reduced speed until you receive a new authority.
• B. Do not proceed; contact the dispatcher for a new authority and confirm the new limits.
• C. Proceed after a grace period is granted by the supervisor.
• D. Proceed with caution and ignore the expiration.

Answer: (B)

Track authority is the permission that authorizes you to move on a specific portion of track, with defined limits and speed. If that authority expires, it is no longer valid, so you must not move. The correct action is to stop and contact the dispatcher to obtain a new authority and confirm the limits before proceeding. There is no grace period or exception for expiration; proceeding with caution or ignoring the expiration would violate the rules and create a dangerous situation.
