To me, it's scary that anyone with a license can drive a 65', 26,000# rig. We have enough people who can't keep straight which pedal is the gas and which is the brake. We've had at least two fatalities in separate incidents in the last year.
We need the federal government to set some standard rules that will cover you when you're out of state. The funny thing is that it can be done under the interstate commerce clause.
