Pennsylvania State Police tell Erie News Now the commercial vehicle traffic ban on Pennsylvania interstates and speed reduction to 45 miles per hour over the weekend was effective in reducing weather-related accidents.

Tractor trailers, buses and other commercial vehicles were banned on the interstates, including I-90 and I-79 here in northwest Pennsylvania, however tow-truck operators were allowed through to assist motorists.

The ban was lifted Sunday afternoon and speeds restored. PennDOT imposed the restrictions Friday when Gov. Tom Wolf declared a state of emergency.

Erie News Now checked in with some trucking companies. They said the ban meant a loss of revenue for their drivers, as they were sidelined and unable to get their deliveries through on time.
