Pennsylvania has targeted five “heavy-truck crash corridors” for extra enforcement, improvements and public education, according to the Allentown Morning Call.

According to a report recently submitted to state lawmakers, Pennsylvania ranked second only to Texas for the number of crashes involving large trucks in 1998. The 7,300 crashes resulted in 192 deaths and nearly 6,000 injuries.
The five corridors were first identified in 1998. Included on the list is all of Interstate 95; U.S. Route 22 from Monroeville to Altoona in western Pennsylvania; state Route 61 from Interstate 81 to Reading; state Route 41 from U.S. Route 30 through Chester and Lancaster counties to the Delaware line; U.S. Route 11/15 from Amity Hall to Selinsgrove; and Interstate 581 in Harrisburg.
Under development are electronic devices that can detect trucks and other vehicles that speed, tailgate or run red lights. Police could use the information immediately to pull over and ticket offenders. Officials say similar automated enforcement devices are being used in New York City and California. However, Gary Hoffman, PennDOT's chief engineer, told the paper that he was concerned about privacy issues.
In a separate pilot project, PennDOT already is experimenting with an electronic device that weighs trucks as they approach a curve, estimates their speed and flashes a warning if they are in danger of rolling over. Two of the devices are positioned along Interstate 83.
