What do you do if there is no cash toll booth open on NJ turnpike?

If there is no cash toll booth open on the NJ Turnpike, you can use an E-ZPass if you have one, as the lanes will still be operational for electronic toll collection. If you don't have E-ZPass, you can proceed through the cashless toll lanes and follow the posted instructions for payment, which may include using a website or mobile app to pay your toll after your trip. Make sure to keep your receipt or any information provided for reference.
