Mary Peters, FHWA Administrator:

“…it appears that we also have grown accustomed to more than 41,000 highway related fatalities and greater than 3 million highway related injuries each year—”

Mary peters fhwa administrator1
Mary Peters, FHWA Administrator:

“This is a terrible toll and should not be viewed as the ‘price we have to pay’ for mobility. These statistics point to a national safety crisis.”

Mary peters fhwa administrator2
Mary Peters, FHWA Administrator:

“FHWA views improving safety asone of its most vital goals and has decided consciously to concentrate on saving lives.”
