Gas truck turning over
3rd world driver - knew nothing about driving. Brakes are either totally out of adjustment, or worn out - probably both! Truck is under-powered, not running right, or wrong gear being used - probably all three! In all likelihood a water truck, not gas, as it would have caught fire immediately. Shitty tank has no baffles in it to prevent severe sloshing - that's what made it do the wheel stand. Most of these fools should not be allowed to even look at a truck, much less attempt to operate one! Jesus Wept!
