What you've typed is spot-on. Regulations; ever ongoing. Freedom of driving big trucks is now more microscoped than if you worked in a factory or at a desk job. Penalties can be severe.
Then there is weather. Your first winter driving is coming up. There are exciting times in the winter. Black ice is worst. Heavy snows means crawling along at 25 mph endlessly. You mostly seem to stay in the midwest area, totally different experiences in the eastern or western mountains. Braking can easily cause jackknife. I used to drive doubles year around, god, last thing I wanted to do was brake on snow or ice. With so many brake shoes on your wheels, all not in exact sync with one another, you don't know where you're going to wind up and two trailers jack instead of one. It happens so quickly.
A lot of semi drivers are trying to get in to expediting because of what you've stated. At the moment, the expediter market is supposedly swollen, but could change if this driver shortage bull-roar has any merit to it. Looking to ship product means any way possible.
