I second this. The working hours and toll sitting in a tractor like that all day are bad, but if you do things like cut hours for drivers, especially the drivers that aren't owner-operators, and continue them at the same pay, you unfortunately will push a huge contingent of people further out into the margins. I am all for increased safety, and very much think the drivers are on the road way too much, but I fear additional safety or hours cuts will be disproportionately borne by the drivers, who really usually can't afford it anyways. Apparently truck driving is a very common job to work too[1].
