When a signal indicates a diverging route, what action is required?

• A. Proceed immediately if safe
• B. Stop until you confirm the route is set and clear for the diverging path
• C. Back up to the previous signal
• D. Take the diverging route as conditional

Answer: (B)

When a signal shows a diverging route, you must stop and verify that the diverging path is properly set and clear before moving onto it. The diverging route must be set in the interlocking for your movement, and the track ahead on that route must be free of any trains or obstructions. Only after you confirm the route is set and clear may you proceed through the diverging path. This protects against entering a route that isn’t prepared or that could be occupied, which is why rushing ahead is not allowed. Taking the diverging route as conditional isn’t permitted unless a signal explicitly grants conditional authority.
