A fake E-ZPass email was sent nationwide telling recipients to pay for toll road use. ( E-ZPass / July 15, 2014)

Amid confusion following the switch to a cashless system on Orange County toll roads, drivers nationwide received a phishing email that said they owed fees for driving on a toll road.

Published beneath a logo that mimics the E-ZPass design, the fraudulent message reads, "You have not paid for driving on a toll road. This invoice is sent repeatedly, please service your debt in the shortest possible time."

Neither The Toll Roads, which manages the Orange County toll road system, nor E-ZPass, which provides electronic tolling on the East Coast, sent the email, according to news releases from both agencies.

The groups advise not opening or responding to the email. Instead, they recommend that questions about an E-ZPass message be directed to E-ZPass customer service.

In California, FasTrak transponders are commonly used for toll collection.
