What situation is likely to cause off-tracking or cheating in a turn?

• A. Pulling a single trailer
• B. Driving at high speeds
• C. Triple towing a 45-feet trailer
• D. Driving in adverse weather conditions

Answer: (C)

Off-tracking occurs when a vehicle travels a different path than its trailer during a turn, which can lead to the trailer not following the same trajectory as the towing vehicle. This is particularly pronounced in scenarios where there is a longer trailer, causing a greater angle during the turn. Triple towing a 45-foot trailer significantly increases the length and weight of the vehicle combination. As the truck and trailer make a turn, the rear trailer is unable to follow the same arc due to its length; thus, it can swing out wider, resulting in off-tracking. The combined length and the necessity for a larger turning radius mean that maintaining alignment becomes more challenging, increasing the risk of the trailer veering off course. The other scenarios might contribute to driving complications, but they do not inherently increase the risk of off-tracking in the same way. For example, pulling a single trailer generally follows the path of the towing vehicle more closely. High speeds can affect handling but are not specifically indicative of off-tracking situations. Adverse weather conditions introduce additional challenges but do not specifically address the mechanics of off-tracking related to trailer length.
