E-ZPass users will save 17 percent over those who pay with cash on the Pa. Turnpike.
Turnpike officials said cash fares will go up on most of the state's toll roads by 10 percent on January 1.
Since electronic rates will not go up, E-ZPass customers will pay about 17 percent less than cash customers.
With the new rates, the most-common cash toll for passenger vehicles will increase from $1.10 to $1.25 and commercial trucks will pay 90 cents more for the most-common cash toll.
Turnpike officials said it costs about four times more to process a cash transaction over an electronic one.
About two-thirds of turnpike customers already use E-ZPass.
