I work across the street from a large paper mill. It's a constant stream of freight trucks in/out of the place. Just to name a few, at least a few times a week, one of your finest flip flop wearing drivers will jackknife, blocking the roadway, or someone will drag a landscape boulder the size of a car into the road. They'll hook and tear down utility poles, jersey barriers and fences as well.
I'd imagine truck driving schools are short on instructors just as bad as the trucking industry is short on drivers. So short, the standards have slipped IMO.
Couple that with how clueless your average (car) driver is on the roads these days, I have great respect for good truck drivers.
Yes the tractors have gotten about as easy to drive as an average bro-dozer, but it still takes the patience of a saint and skill to navigate the payload around.
