A bill aimed at slowing down motorists in highway work zones is headed to Governor Tom Wolf's desk. The bill would allow the use of automated speed enforcement systems - i.e. cameras-to monitor the speed of vehicles through construction zones and issue tickets to violators. A first offense would result in a written warning, with fines for subsequent offenses as high as 150 dollars. Bill co-sponsor State Senator Judy Schwank says it sends a clear message. Senate passage brings to an end a four year process for this bill, with supporters saying it's gone through half a dozen revisions in the Senate and the House.
