Google Maps & Tolls FAQ

Is there a way to display toll roads on Google Maps?

Google maps allow you to “avoid” toll roads. Google maps indicates that your route includes a toll road or partial toll road. Google maps do not show toll roads as a layer or toll locations or toll amounts as markers.

How to avoid tolls on Google Maps
Does Google maps show tolls? What are tolls on Google maps?

Google maps does not show tolls. However, it indicates presence of toll roads in turn-by-turn direction. You can use Tollguru™ Toll Calculator to see tolls on Google maps for all the logical routes between your origin and destination.

Toll Calculator FAQ

How to use Tollguru™ Toll Calculator?
How does the Toll Calculator work?

The toll calculator estimates costs (tolls + gas) for all logical routes between your origin (start location) and destination. It shows you the cheapest, the fastest, and other relevant routes on a Google map. To help you choose between routes, it displays cost, time, distance and other information for each route.

The travel times and gas costs vary based on traffic congestion, accidents, road closures, etc. For example, your vehicle consumes more fuel in stop and go traffic. Every time you search, the travel times and gas estimates may be different. The toll calculator shows tolls at the time of your travel for variable priced toll roads. As you can see the estimates of fuel consumed and gas expenses, travel times, and tolls are dynamic. Therefore, the cheapest route and the fastest routes may change for the same origin and destination.

How does Toll Calculator calculates tolls?

Tollguru™ considers the following factors to calculate tolls for your vehicle

  • Day and time-of-the-day. For example, tolls on SR 133, 241, 261 toll roads, SR-91 Express lanes in California are different each day of the week, and during peaks, pre & post-peak hours on a day. Please refer to toll information for your state to learn more.
  • Vehicle class based on
    • Number of axles for car, SUV, pick-up, truck, RV/motorhome, bus, motorcycle
    • Whether dual tires
    • Whether towing a trailer
    • Height, weight of vehicle
  • Method of payment
    • Tag transponder such as E-ZPass, SunPass, TollTag, TxTag, FasTrak, I-PASS, PikePass, AutoExpreso, etc.
    • Cash (or credit/debit card)
    • Video payment systems such as Pay By Plate, ZipCash, TollByPlate, Pay by Mail, License Plate Toll etc.
  • Vehicle occupancy (carpool) *
  • Discount program *

For roads where truck tolls are based on weight and height, Tollguru™ uses a relationship between weight, height and number of axles to calculate tolls. Please refer to individual state pages to see truck toll payment information for your state.
If a method of payment cannot be used throughout a route, it is shown as . For example, if you cannot pay using cash for all toll plazas, bridges, and tunnels in your route it is shown as . However, you will be able to see tolls for individual toll plazas, bridges, and tunnels in the toll calculator on website.

To keep it simple, Toll calculator currently does not display tolls for carpooling, and enrollment in discount programs

Truck Toll Calculations FAQ

How do you show tolls for trucks based on axles when the toll agency charges based on weight and vehicle height?

As you are aware, some toll road agencies charge tolls based on weight and vehicle height. Tollguru™ toll calculator uses a relationship table between truck weight and number of axles. For example, you can see the table showing relationship between weight and axle for Pennsylvania turnpike here. Please refer to individual state pages for information for all facilities where tolls for trucks are not charged based on axles.

If we do not use a relationship between weight and axles, we will not be able to show total tolls for routes where one toll agency in the route charges tolls based on axles and another agency charges tolls based on truck weight.

Why do you show different tolls for 2-axle trucks?

On many toll roads you have to pay different tolls if you drive a 2-axle pick-up with 4 tires, 2-axle pick with 6-tires, or if you drive a 2-axle commercial truck. Often the tolls are same but on some roads they are not. You can pick appropriate vehicle class (personal pick-up truck or 2-axle truck) to get the correct toll.

Gas Expenses FAQ

How does Tollguru™ calculate gas expenses for my route?

Tollguru considers following factors to calculate gas costs for your route

  • Highway and city fuel efficiency (MPG) of your vehicle
    • Calculated based on your vehicle class
      • Further, refined based on year, make, and model of your car, SUV, pickup
    • You can edit fuel efficiency, if different
  • Route distance
  • Traffic speeds. For example, your vehicle uses more fuel in stop and go traffic and when the traffic speeds are very high.
  • Gas costs

Tollguru™ uses a proprietary algorithm to calculate gas costs based on traffic speeds. For example, fuel efficiency for most cars is 20 percent lower at 75 miles per hour compared to 55 miles per hour. Tollguru uses speeds for each travel leg in a route to calculate gas costs.

It is important to remember that gas estimates are highly subjective based on type of fuel, your vehicle condition, and your driving type. Also, we use average gas costs. It is important to remember that your fuel costs depend on where you fill your tank.
How does toll calculator estimate gas costs in my location?

The gas costs are estimated using data from users around your location. If no gas cost estimates are known, the toll calculator shows a default gas price that you need to update based on what you paid at the pump.

Cheapest and Fastest Routes FAQ

What is the cheapest route?

The cheapest route has the least combined cost (tolls + gas). It may be the fastest route. If it is not, you will see information about how much longer it will take you on the cheapest route compared to the fastest route.

Tollguru™ uses tolls that you will pay if you have a valid Tag transponder (E-ZPass, SunPass, TollTag, TxTag, FasTrak, I-PASS, PikePass, AutoExpreso, etc.) to calculate the cheapest cost. If tolls are not collected electronically, the toll calculator will use cash tolls to check the least combined cost (tolls + gas)

How do you decide on the fastest route?

The fastest route takes the least amount of time. Sometimes, but not very often, it can be the cheapest route.

Why is a toll for a route shown as

indicates that you cannot use the particular method of payment on some or all the toll collection locations throughout your route.

  • If “Tag” toll is , you cannot use Tag (E-ZPass, SunPass, TollTag, TxTag, FasTrak, I-PASS, PikePass, AutoExpreso, etc.) for some or all of the toll plazas, bridges, and tunnels on your route. However, you can see tolls for individual toll locations in the toll calculator .
  • If “Cash” toll is shown as , you cannot pay toll by Cash (or credit/debit card) at one or more locations.
  • Similarly, if the agency will not take a photo of your license plate to bill you toll on one or more locations in your route, Video toll (Pay By Plate, ZipCash, TollByPlate, Pay by Mail, License Plate Toll etc.) is shown as .
What does “Compare” screen do?

The “Compare” screen shows all the routes between your origin and destination. You can see distance, time, and cost for all the available routes. Click on the route to pick your route. You can see tolls by clicking on information. To get turn-by-turn direction, click on the “Direction” screen. It will send you to Google maps app, Apple map app, or your other favorite app service for voice-guided turn-by-turn directions.

Should I always avoid a toll road?

You will find that depending on distance on the alternate route, gas price, and fuel economy of your vehicle, using a toll road can be cheaper or only marginally expensive than toll-free route. Alternately, depending on traffic conditions, fuel economy, and gas prices toll-free route might be the fastest route.

Payment Options FAQ

How do American toll roads collect payment? Why do you have different toll payment methods in toll calculations?

On most USA toll roads, bridges, and tunnels you will have three payment options to pay your tolls.

  • If you install a Tag, an eligible transponder (E-ZPass, SunPass, TollTag, TxTag, FasTrak, I-PASS, PikePass, AutoExpreso, etc.), you do not need to stop to pay the toll. This toll is “Tag” toll.
  • If you do not have an eligible Tag installed, some tolling agencies take a picture of your license plate and send you a bill. This toll is “Video” (Pay By Plate, ZipCash, TollByPlate, Pay by Mail, License Plate Toll etc.) toll.
  • At some locations, you stop and pay toll by cash or credit or a debit card, the toll is “Cash” toll.
  • Enroll in Peasy for convenient, multi-state, pay-as-you-go tolling service. With Peasy, you don't have to stress about pre-funding a toll account, getting hit with unexpected penalties or fines, or having to pay tolls by mail.
How do I pay a toll?

In the past, there was no standard way to pay your tolls. Tag transponders are not interoperable. If you have transponder for one road, it may not work on another. Good news is that now you can enroll in Peasy to pay all your automated tolls easily. With Peasy, your vehicles are enrolled in the national Peasy network, allowing you to drive on covered toll lanes and bridges throughout the U.S.

Learn how you can break free from tag transponders, which lack interoperability. Depending on the toll road you traverse, you would need to install a specific Tag (E-ZPass, SunPass, Good To Go, TxTag, FasTrak, I-PASS, etc.) in your vehicle for electronic toll payment. Peasy removes the need for multiple transponders and ensures your cashless tolls are paid on time.

Please refer to toll information for your state to learn more about toll payment options such as state specific tag transponders and cash tolls.

Rental Cars & Tolls FAQ

I will be traveling in a rental car. How will I pay for tolls?

The easy but perhaps expensive option is to sign up to pay tolls through your rental car company. If you want to avoid paying toll penalties and administrative charges later, you need to know if you can pay tolls by cash on your route. You may want to use Tollguru™ Toll Calculator to check toll locations on your route and whether you can pay by cash. If you do not know the exact location of the cash lanes, you may travel through the transponder lane by mistake.

You may want to bring your own toll transponder, but it may not be the best solution for two reasons.

  • Most toll agencies such as NTTA, TxDOT in Texas, do not want you to use transponder from one car into another car. You may have an eligible transponder in your car but if the transponder is not read, the tolling agency will bill the “registered owner” of the car, which is the rental agency.
  • Transponders are not inter-operable. For example, you cannot use California FasTag in E-ZPass, TxTag, or SunPass lanes.

In both cases, the toll agency will bill the registered owner of the car - the rental car agency. You will need to pay penalties, if you did not sign up to pay tolls through the rental car agency. Depending on your needs, you may want to sign up to pay tolls via the rental car agencies. Refer to the SunPass rental car page for details. The following table summarizes toll charges from car rental agencies.

Rental car agency Daily fee Monthly/ Rental maximum Flat fee per day Comments
Advantage $4.95 $24.75 Plus higher toll-by-plate rate
Hertz $4.95 $24.75 Plus higher toll-by-plate rate
Firefly $4.95 $24.75 Plus higher toll-by-plate rate
Avis $3.95 $19.75 Tolls at cash rate
Budget $3.95 $19.75 Tolls at cash rate
Payless $2.95 $14.75 Tolls at cash rate
Dollar $10.49  Per-toll charge of $9.99 plus toll, if not enrolled in flat fee program
Thrifty $10.49  Per-toll charge of $9.99 plus toll, if not enrolled in flat fee program
Fox $90.00 $8.99   $15 per toll plus the cost of each toll
National $3.95 $19.75 Tolls at cash rate
Alamo $3.95 $19.75 Tolls at cash rate
Enterprise $3.95 $19.75 Tolls at cash rate
Silvercar You pay just the tolls
Sixt $7.99  $5.00 administrative fee + tolls

As you can see from above table, if you do not rent from Silvercar, you will need to pay fees in addition to the toll charges.

Depending on your destination, you can also prepay tolls.

Navigation & Location Share FAQ

What if I do not want to share my location?

For the app to work best, Tollguru™ recommends you share your location. Tollguru will pick your start location. You will be able to search your destination such as a restaurant, gas station, etc. without having to type the exact address.

Why do the Google maps app not show the route I selected for turn-by-turn direction?

The turn-by-turn navigation that Google maps app or other apps are for a default, fastest route. However, you will be shown the route of your interest. Please click on your preferred route for navigation. If you use a browser, you will the actual route from Tollguru™ Toll Calculator when you click on "Get Direction."

Toll API Usage & Bill FAQ

How are the Toll API transactions counted?

If you request with one origin and one destination, TollGuru™ Toll API needs to query two geocode requests to Google or HERE Maps API, two direction requests to Google or HERE maps API, and one Toll (plus gas) transaction to Tollguru Toll API. This leads to 2 geocode + 2 direction + 1 toll = 5 transactions.

If you requests for one origin, two stops and one destination, it would be 4 geocode requests + 2 direction requests + 1 toll request = 7 transactions.

If you sends a route polyline (with as many stops as you want) based on HERE maps or Google maps without necessitating any queries to Google or HERE maps API, it will be just one transaction.

If you are querying for trucks, buses and RV please use HERE maps API. Do not use Google maps as Google Maps API does not provide routes for trucking. You may be routed on truck prohibited routes.

How is the Toll API bill calculated?

The API Toll bill is calculated based on your usage plan and the number of transactions in the usage period. For example, if you sign up for the Starter plan, you will pay $40 per month for up to 5,000 transactions. If you end up making 7,000 transactions to Tollguru™ Toll API during the usage period, you will pay $40*7,000/5,000 = $56, if you make 20,000 requests, you will pay $40*4= $160 and so on.

If you sign up for Basic plan, you will pay $130 for up to 20,000 transactions. If you make 100,000 transactions during the usage period, you will pay $130 * 5 = $650.

If you already know you will have high number of transactions, it may be a good idea to sign up for a higher plan (as you will get discounts compared to signing for the lower plan).

When is bill generated?

All our API usage plans are based on monthly billing cycle starting the day you sign up for the plan. The invoice for each usage period is billed and sent out at the end of usage period. For example, you signed up for the Starter plan on Jan 5th, your first usage period would be Jan 5th to Feb 5th. The invoice for this period will be billed and emailed to you on 5th Feb and so on.

When is payment set-up?

All our API usage plans are based on monthly billing cycle. The credit card details are required when you subscribe for a particular plan. The account is charged at the end of the monthly billing cycle based on subscribed usage plan and actual usage.

What if I change plan in middle of the month?

If you change your subscription plan in the middle of the month, for that period, you pay pro-rated charges based on current plan. For the remaining time period in the month, you pay pro-rated charges based on the updated subscription plan.

How does the subscription renewal work?

The subscriptions to all our API usage plans are autorenewed at the end of monthly billing cycle. Your subscription is active until you unsubscribe from the plan.

Other FAQ

How do Express lanes and managed lanes work? Why do you not show tolls on Express lanes?

Express lanes and managed lanes are typically built within an existing highway. They often add capacity to the highway to accommodate more traffic to relieve congestion. However, unlike other toll roads, the price changes based on the level of traffic on the parallel free road. The tolls vary based on congestion and are not known before you travel. Since the toll rates are not published ahead of time, the Toll calculator cannot calculate tolls for these facilities.

Some Express lanes such as SR-91 Express lanes publish their toll schedules ahead of the time. Tollguru™ Toll Calculator calculates tolls for such Express lanes.

If I took my license plates off, can I use toll roads for free and if so will I get caught?

We will not recommend taking license plates off. It is illegal and you may face stiff penalties. If you’re driving around town with no license plates on your car, toll booths are the least of your worries. You can be stopped by cops anywhere. Some drivers resort to innovative methods (such as mechanical contraptions) to hide their license plates at the toll plazas. It does not work every time. When caught they pay a great deal more money to get out of the trouble than you would have paid in tolls. We will recommend using Tollguru™ Toll Calculator to calculate your tolls before you travel. You will not be surprised at the toll gates or when you get a bill in mail for all-electronic toll facilities.

Why do some states have toll roads and other don’t?

Most roads are built with local, state or federal dollars raised from taxes. Tolls roads only charge (tax) users of the facility. For example, E-470 toll road did not use any tax dollars to fund its construction. Some of the toll roads such as Pennsylvania turnpike were build prior to the construction of tax-dollar based interstate highway system and remain in places. States and cities now construct managed lanes and express lanes using bond financing to provide travel options during peak hours. Therefore, whether the state has a toll road depends on history, current demand for roads, whether the state has tax revenues to build new roads, and whether building toll roads are an option.
