Samenvatting
One of every three tractor- trailers can be expected to crash in a year, compared to one of every 13 passenger car and one of every 26 smaller trucks. Of course, tractor- trailers are driven more miles than other vehicles, and their overall crash rate is lower than that of passenger cars. But on the kinds of highways were truckers mostly travel, the crash rate is higher for big rigs than for passenger cars. And the rate of fatal crashes per mile on all highways is much higher for big trucks than for cars.
