Wow. I had no idea it was this bad. And you didn’t even touch the hazards of actual driving for 8 hrs a day, often on tricky mountain passes, with heavy snow
Quick look, they did change the rules since I quit in 2012. Looks like a 60/70 hour limit in a 7/8 day span.
Though, you're restart is a wonderful 34 hours time-off in... a loud truck stop in the middle of nowhere. Always.
Oh, but you are protected (and I believe the insurance companies help with this too) that if a driver says road conditions are too dangerous, the company can't force them to drive anymore. Doesn't stop them from punishing you afterwards with too little loads.
