The Pennsylvania Turnpike is telling people to pay their unpaid tolls. The Turnpike Commission yesterday said it is ramping-up collection efforts to get some of the 180-million dollars in tolls that remain unpaid. No one is saying just how much of that 180-million the commission expects to recoup. Drivers who don’t pay their tolls could see their registration suspended after they rack up 250-dollars in tolls. The Turnpike Commission says it works with collections agencies to get those unpaid tolls paid, but about 40-percent of the Turnpike’s unpaid tolls are owed by out-of-state drivers who cannot be suspended. Lawmakers say that’s a problem.
