Which trailer is most prone to turning over when making a sudden turn while pulling doubles?

The rear trailer is the most prone to turning over when making a sudden turn while pulling doubles due to its position and the dynamics involved in maneuvering. In a double trailer setup, the rear trailer is typically less stable because it is further from the pivot point created by the towing vehicle and the lead trailer. When a sudden turn occurs, the rear trailer experiences forces that can cause it to tip over more easily, particularly if the turn is sharp or made at higher speeds.

Additionally, the longer overall length of a double trailer setup means that the rear trailer is subject to more swing and lateral movement. This can amplify the risk of instability, especially during abrupt directional changes. In contrast, the front or lead trailer receives more stability from the towing vehicle and better weight distribution, which contributes to lower rollover risk in sudden maneuvers.

Understanding these dynamics is essential for safe operation and effective control while driving with double trailers. Proper turning techniques, maintaining appropriate speeds, and being mindful of the trailer's behavior during turns are crucial for avoiding rollovers.
