Identify the first concern when stopping a semi-tractor/trailer.

• A. Remember that you have a long crisis zone
• B. If they keep going ask yourself if they are looking for a safe place to pull over
• C. Stopping site location, flat level is most preferred
• D. You should immediately pursue to ensure control

Answer: (C)

The first concern when stopping a semi-tractor/trailer is finding a stopping location that is flat and level. A level surface provides stability, so the rig won’t roll or shift after you stop, and it makes it safer to apply the parking brake and use wheel chocks. Slopes, soft shoulders, or uneven ground can cause the trailer to drift, settle, or sink, increasing the risk of movement or loss of control even after you’ve stopped. Once you’re on a flat, firm surface, you can secure the vehicle properly and attend to other safety steps. The other ideas aren’t as immediate or reliable for safety: a vague notion of finding a “safe place” when the vehicle continues, or pursuing after stopping, aren’t as critical as ensuring a flat, stable stopping surface.
