Frankel says 'the evidence is in,' citing doubling of riders' head injuries since repeal HARRISBURG, June 29, 2006 - State Rep. Dan Frankel, D-Allegheny, today introduced a bill to restore Pennsylvania's motorcycle helmet requirement for people 21 and older. "The evidence is in. Repealing the helmet law three years ago has led to a doubling of serious head injuries to motorcycle riders - an increase of more than 200 more serious head injuries," Frankel said. "This report and Ben Roethlisberger's accident should be all the wake-up calls we need."
