"What we have in common is too few truckers. In the UK instance that is a self-inflicted wound."

Not quite true. Here in the UK Brexit has played a part in the problem. There was no testing of HGV drivers for over a year, so we lost out on new drivers entering the industry. We have also had the problem of fewer people wanting to be drivers, along with older drivers retiring earlier. The poor conditions and low wages are mainly to play for that.

In the USA you don't have our Brexit problem. You didn't have our nationwide lack of issuing new HGV licences. I assume your licences are issued on a state by state basis. Yet you have a shortage of drivers along with problems at your west coast ports.
