Something both experienced and inexperienced drivers need to be concerned with jack-knifing. Basically this is when your tanker truck (or any truck pulling a trailer) has the trailer slide around towards the front of the truck.
Once the trailer exceeds a 45 degree angle (compared to the normal straight line of travel), jack-knife will happen.
There are many reasons why this can happen, with experience being only one of them. The most common is when the trailer actually moves faster than the truck!
Tanker truck drivers (or any truck hauling a trailer) have a greater chance of experiencing this on icy or wet road or on one of the dangerous roads in USA. It has also occurred when the trailer is empty and the driver tries to brake too fast.

7. Type Of Tanker Trucks
I already covered what a tanker truck is (heavy, medium, light) and their loads limits and sizes. But what do they actually do? Of course they haul stuff, usually liquids or gases.
