Answer options
- AWhen driving into a strong headwind

- CWhen cruising at a steady speed on a level road
Why
Inside a smooth bore tank there are no baffles or bulkheads to slow the liquid down, so it surges forward and back with great force. As you start moving it rushes to the rear, and as you brake it rushes to the front, shoving the truck both times; that is why starting and stopping demand the most care.
