  • I entered an E-ZPass lane unintentionally, what should I do?
    • If it is within 7 days of your trip, you may make a payment by visiting and selecting Pay a Toll. If your trip was more than 7 days ago, you are unable to pay the toll until you receive a First Invoice in the mail. Once you receive the invoice you can submit payment for the toll and and the $1.00 processing fee per transaction. As long as you submit the payment by the due date no further action will be required. Please note that invoices escalate to a Second Invoice with a $1.50 processing fee per transaction after 30 days and then to a Notice of Toll Violation 30 days thereafter, and a $25.00 fee will be applied. If you wish to dispute the invoice you need to complete Section B and D explaining your situation and return the invoice with a check for the toll fare. The E-ZPass Customer Service Representatives will review your explanation and determine if this is an inadvertant unpaid transaction per New Hampshire E-ZPass Rules & Regulations. If so, your processing/administrative fee will be waived. All customers, except those paying through the Website, will receive a determination letter (DTR) from the Customer Service Center noting the outcome of your dispute.
  • What is E-ZPass and how does it work?
    • E-ZPass is an electronic toll collection system, which takes cash, coins and toll tickets out of the toll collection process. Instead, drivers establish an account, prepay tolls and attach a small electronic device to their vehicles. Tolls are automatically deducted from the prepaid account as an E-ZPass customer passes through the toll lane. For additional information, visit
  • I sometimes pull a camper or trailer with my vehicle. Can I still use E-ZPass?
    • Yes. In this instance the equipment in the lane is designed to identify that your vehicle is pulling a trailer and you will be charged accordingly. However, if you think this will be a regular occurrence, you should call the Customer Service Center and have them send you a transponder programmed for the vehicle classification you use most frequently. You should never use your transponder in a vehicle type other than the one you initially requested such as a car transponder in a tractor-trailer.

  • I have an E-ZPass account. What lanes can I use at the toll plazas?
    • Most toll plazas have "DEDICATED E-ZPASS ONLY" lanes which will get you through the plaza quickly. These lanes have signs mounted on top of the toll plaza canopy and they are quite distinguishable from the other lanes. E-ZPass account holders may use mixed mode lanes (staffed lanes) as well. Essentially, E-ZPass account holders may use any lane where the E-ZPass Service Mark is displayed.

  • What is the speed limit through an E-ZPass only lane?
    • The maximum speed is 25 MPH. The reason for this is safety of the motoring public and safety of our employees that could be crossing toll lanes at any time.
  • Could I get a speeding ticket for going too fast through an E-ZPass lane?
    • Maybe … NHDOT has no authorization to issue speeding tickets. This is a Department of Safety - NH State Police issue. If a State Trooper is monitoring speed through the toll lanes, and you exceed the posted speed through the E-ZPass lane, you could be issued a summons.
  • I opened my NH E-ZPass account at a Walk-In-Center when will by transponders be activated?
    • Transponders will not be active immediately. They will require between 48 and 72 hours to be activated.
