Frequently Asked Questions

What is a transponder?

A transponder is an electronic device you attach to your car to pay for tolls so you don't need to stop and pay with cash.


Do I need a transponder to drive on a toll road in the US?

In most instances the answer is 'no' as many toll facilities still accept cash and those that don't will take a picture of your license plate and you will receive a bill in the mail.  However it is often more expensive to bill-by-mail so you will likely pay an additional service fee and possibly a violation charge for driving through a cashless toll gantry without a transponder.


Will Tollsmart let me know where my transponder is accepted?

Yes! The Tollsmart mobile apps allow you to select your transponder from over fifty different options across the US and will inform you of every toll facility along your route where your transponder is (and isn't) accepted by using different color pins to highlight the difference so you can know in advance if you will need to pay in cash or acquire a different transponder.


Does Google Maps display toll prices?

No. Google Maps will notify you when you will encounter a toll along your route and allow you to avoid tolls but it does not yet display toll costs. That is why we created a Google Maps toll calculator, so you can view toll costs along a route.


Does Apple Maps display toll prices?

No. Apple Maps will notify you when you will encounter a toll along your route and allow you to avoid tolls but it does not yet display toll costs. That is why we created the Tollsmart toll calculator for iPhone and iPad. Download it for free from the App Store.


Does Waze display toll prices?

No. Waze will notify you when you will encounter a toll along your route and allow you to avoid tolls, but it does yet display toll costs. The Waze app does allow you enter information related to tolls such as your transponder, which helps identify the Express Lanes you can drive on.


Does MapQuest display toll prices?

No. MapQuest will notify you when you will encounter a toll along your route and allow you to avoid tolls, but it does not yet display toll costs.


How can I save money on tolls?

The best way to save money on tolls is to use a toll tag or transponder as many of these provide discounts off of the cash rate for tolls. However it varies by tolling agency so make sure you understand where toll discounts will be applied when you sign up for an account.


How can I save money on truck tolls?

To save money on tolls for tractor trailers and other trucks use a toll tag or transponder or subscribe to a toll management service like Bestpass that receives volume discounts from toll agencies that they pass on to customers.


Can I pay for tolls with my iPhone?

There are several apps available to pay for tolls with an iPhone or smartphone, such as PayTollo, Peasy and Bancpass.  However none of these yet have universal coverage across all tolling facilities in the US.


What is an EZ-Pass?

An EZ-Pass is a type of transponder that allows you to pay for tolls electronically when driving. It is accepted in toll facilities in 17 states in the Eastern US. Learn more about EZ-Pass on this EZ-Pass tutorial


Is it cheaper to use an EZ-Pass?

There are often discounts provided to EZ-Pass account holders, however it varies by state and tolling facility.  The Tollsmart Toll Calculator will automatically calculate EZ-Pass discounts for you, and you can learn more on this EZ-Pass tutorial.


Do all EZ-Pass users get the same discounts?

No. This is one of the most misunderstood elements of the EZ-Pass program. There is no one single EZ-Pass, rather there are many that are issued by the state or regional tolling authorities and each has its own discount schedule that may, or may not, apply to EZ-Pass's issued by other states or tolling authorities. There is no rhyme or reason to this, which is we have all of these discount scheduled included in the Tollsmart apps so you don't need to think about it. You can learn more about how EZ-Pass discounts vary on our EZ-Pass tutorial page.


Will my EZ-Pass work anywhere in the US?

Unfortunately no.  EZ-Pass currently only works in toll facilities in 17 states in the Eastern US.  If you are traveling to other regions in the US with tolls you will either need to pay in cash or acquire a transponder that works in that region.  To view the 17 states that accept EZ-Pass visit our EZ-Pass tutorial page.


Will my EZ-Pass work in Florida?

No, with the exception of certain toll roads in the Orlando area operated by the Central Florida Expressway Authority (CFX). Learn more on our EZ-Pass tutorial page.


Are there many tolls in Florida?

YES! In fact there are more miles of toll roads in Florida than in any other state in the US.  If you are traveling to Florida and want to learn more about tolls in the state check out our Florida Tolls Survival Guide page.
