Side-to-side surge can cause:
Answer: A
Rollover.
The baffles of liquid tankers do not prevent side-to-side surges. Side-to-side surge happens when making a turn. The liquid will rush (surge) in the opposite direction of the turn. This results in the vehicle's center of gravity increasing to its highest point in the middle of the turn. The higher the center of gravity, the easier it is to roll the vehicle or trailer.
