Since there are "a lot" of these fatal accidents, could you link to two or three of recent occurrence?
We have most of these accidents in our area on the turn off from 93 through Laughlin due to having to bypass the Hoover Dam. It's a steeply-banked road and requires good breaks when carrying heavy loads and most of these accidents are due to faulty brakes/equipment. Our local papers and radio station report these accidents.
