The nation's top transportation official urges manufacturers to provide free or discounted DOT certified helmets or rider safety training with the purchase of every new motorcycle, according to the U.S. Department of Transportation.

"Helmets and proper training are just as important as brakes or headlights when it comes to the well-being of motorcyclists," said U.S. Secretary of Transportation Mary E. Peters today.

Peters said only 58 percent of riders wear helmets today, which is down 13 percent from just four years ago.
