If you cannot establish a route is clear before departing a yard, which option reflects compliant action?

• A. Depart the yard and proceed with caution
• B. Move by hand to reposition equipment while verifying clearance
• C. Wait for the dispatcher to issue a formal clearance
• D. Proceed only after authority is established and the route is clear

Answer: (D)

Before moving from a yard onto a mainline, you must have explicit permission to occupy the track and you must know that the route ahead is clear. This dual requirement protects against conflicts with other trains and workers and ensures you’re operating under a recognized authorization.

The best choice reflects that you proceed only after both conditions are met: authority is established and the route is clear. Without this, there’s no guaranteed protection or coordination with the dispatcher, which could lead to a collision or obstruction.

Moving with caution or repositioning equipment by hand does not replace the need for formal authority and a confirmed clear path, even if you verify clearance. Waiting for a dispatcher’s clearance is important, but it must accompany a confirmed clear route to be compliant.
