On March 10, 2010 the Pennsylvania State Senate held a hearing on the ongoing problems with hit and run drivers in Pennsylvania. As noted on philly.com, there are currently 2 bills under consideration to significantly increase jail time for hit & run drivers who seriously injure or kill others: S.B. 522 and S.B. 1177.
Senate Bill 1049 would result in more jail time for hit & run drivers who are driving under the influence of alcohol or drugs at the time of the crash. Currently, the PA Motor Vehicle Code does not punish hit & run drivers who are impaired more than sober drivers.
