What does the term 'Movement in the opposite direction of authorized movement' describe?

• A. Movement forward
• B. Movement in the opposite direction of authorized movement
• C. Movement in a restricted zone
• D. Movement when authorized by signal

Answer: (B)

In railroad terms, movement that goes opposite to what has been authorized by signals or track authority is called wrong-way movement. This is a safety violation because it bypasses the clear direction and protection provided by the authority in effect, creating a high risk of collisions or derailments. Authorized movement means you have the green light, track warrant, or other clearance to move in a specified direction; going the other way without new authorization means you’re not protected by that authority. So this phrase describes wrong-way movement—moving contrary to the given authorization.
