craziest thing you saw a truck driver do?

[Booboy]

i just came from a road trip to charlotte,nc from illinois.I never seen mountains close up.Going thru west va which is all curves no straight aways going downhill Truck drivers doing 80mph in a70mph zone which had curve that i though was hard for me to take on at 70mph,switching lanes like they were in a sports car and some trucks taking up two lanes to make these turns on a three lane roadway.Stoping for no one reckless i thought.There was signs posting telling truck drivers to go 5mph below speed limits to advoid tipping over.I will add it was dark driving through the mountains at night.
