I know this was a curtainsider with IBC’s but anyone driving a tanker has to be aware of the slow rollover which lucy so eloquently copied 
You also have to be aware when braking and accelerating, the load will move to the back when setting off, then move forward when you brake, you just have to give yourself lots more room and drive with the moving load in mind.
When you are going up the gearbox you can use the momentum of the load to gain speed.
It’s quite good fun driving a tank through town centres in the ice, when you stop at traffic lights with the handbrake on, the truck can still move forward.
Another point which will have all you new drivers screaming Health and Safety is when you pull onto a weighbridge, you leave the brakes off and get out of the cab. otherwise you will be sat 20 minutes till the load stops sloshing around
