To cross between standing cars that are coupled together, what must you do?

• A. Confirm that cars will not be moved, cross car using only end sill platform and keep feet clear of coupler and drawbar.
• B. Cross between cars using any route with caution.
• C. Use a ladder to reach between cars.
• D. Cross between cars is prohibited.

Answer: (B)

Crossing between standing, coupled cars requires careful judgment and steady, deliberate movement to avoid injury from moving parts or gaps. The best choice recognizes that, when you must cross, you should proceed with caution and use the route that gives you solid footing and a clear handhold while staying away from the coupler and drawbar. This reflects the practical need to assess the immediate environment and pick the safest path available rather than adhering to a single fixed method. While ladders are unsafe for this task, and a blanket prohibition is overly rigid, the emphasis is on calm, controlled crossing with awareness of potential car movement and the hazards around the end of the cars.
