What are the risks of hauling liquid in a smooth bore tank?

a.No risks beyond a normal trailer
b.Maximum surge effect with no baffles to slow liquid movement, increasing stopping distance and rollover risk
c.The liquid freezes more easily
d.The tank is more likely to corrode

Explanation

Smooth bore tanks present the maximum surge effect because there are no internal baffles to reduce liquid movement. This means the liquid can build up strong forward-and-back and side-to-side surge forces, significantly increasing both stopping distance and rollover risk.
