When turning suddenly while pulling doubles, the rear trailer is most likely to turn over. This stems from the dynamics of how trailers operate during tight maneuvers. The rear trailer is more susceptible to overturning due to its position and the way momentum shifts when a sharp turn is made. As the front trailer turns, it exerts a force that can cause the rear trailer, which follows behind and is not as directly aligned with the turning path, to sway or swing out. This can lead to it tipping over if the turn is sharp enough and if the speed is excessive.

Understanding the design and behavior of trailer combinations is crucial for safety. When engaging in maneuvers, drivers should be particularly cautious about maintaining control of both the front and rear trailers to prevent accidents, especially in tight spaces or when making quick turns.
