Yup, truck drivers make mistakes too. Classic. Come down an on ramp to the freeway too fast. Truck rolles to one side, compresses springs. Truck gets on freeway, springs uncompress, trailer pops back up, load shifts, plop trailer goes on side, (or all over the place.). Classic screwup by truck driver.

I took a driving school for trucks. My rule (from school) if the ramp is posted at 40 I do 20, 30 I do 15, or 1/2 of what is posted for cars. Never dumped a load, or even knocked a stack over in the trailer. Had lots of cars beeping their horns at me for being too slow. But I alwise figgred they would rather be a little late, instead of being the 2nd one there at a truck wreck.

Usualy didn't worry too much about motorcycles. They were fast enough that they didn't get in my way at all.
