Trucks have pretty much got the roads to themselves now, so have an enormous amountof space, if they make a mistake there is room. They will still be making mistakes, possibly taking a few liberties too.

There is very little private car traffic here at night, yet often on the traffic news there is a single vehicle truck crash in the small hours or two trucks crashing into each other.

If the density on roads was like this all of the time there would be fewer crashes for everyone.
