An E-ZPass transponder is a small electronic device you attach to your car's windshield to pay for tolls on a trip. It allows you to use the high speed cashless lanes on toll roads, bridges and tunnels where E-ZPass is accepted, and often provides discounts to the cash rate depending on the state that issued the E-ZPass. Important to note is that many existing toll facilities are converting to cashless tolling meaning if you don't have a transponder a picture will be taken of your license plate and you will receive a bill in the mail that frequently will include a service charge and end up more expensive than the transponder rate.
With the exception of certain Express Lanes (which are optional to drivers) you will not need an E-ZPass to drive on toll roads in the 17 states where E-ZPass is accepted. You do however need an E-ZPass to drive on the toll lanes that are designated E-ZPass only.
E-ZPass is accepted at toll facilities in the following 17 states:
There is no charge to get an E-ZPass transponder, however some states like Illinois require you to put down a refundable $10 deposit (please view your state's specific requirements using the links above). Note however that your credit card will be charged an initial amount of prepaid tolls from $20-$35 which will be replenished when the balance is drawn down below a certain amount.
That depends upon which state your E-ZPass was issued and which toll facility you are on. It varies from state-to-state as states like Maryland choose to provide discounts to their residents and so only apply discounts for E-ZPass transponders issued by the Maryland Transportation Authority. In other instances, like the Lincoln and Holland tunnels into New York City discounts are applied to all E-ZPass holders, regardless of state of issue.
This can be quite confusing as there really is no rhyme our reason, and given that there is no E-ZPass Toll Calculator that works across all of the states we've built all that logic into the Tollsmart application so you don't have to think about it! And this applies to all transponder discounts across the US such as SunPass in Florida, TxTag in Texas and FasTrak in California.
An E-ZPass Flex is a version of an E-ZPass transponder that allows you to flip a switch to indicate that you have enough passengers in your vehicle to travel for free on certain Express Lanes within the E-ZPass region. The E-ZPass Flex works just like a regular E-ZPass and is accepted in all toll facilities that accepts an standard E-ZPass transponder. Express Lanes are often also referred to as HOT lanes as they have converted the HOV (High Occupancy Vehicle) lanes to allow vehicles that did not meet the carpool minimum passenger requirement to travel on them by paying a toll, thereby becoming High Occupancy Toll lanes. However to distinguish HOV from HOT vehicles a new type of transponder was required, and the E-ZPass Flex was born.
An E-ZPass Plus allows you to use your E-ZPass to pay for parking, mostly at certain airport garages in New York and New Jersey. E-ZPass Plus is currently accepted in the following locations:
