  • I entered an E-ZPass lane unintentionally, what should I do?
    • The registered owner of the vehicle will receive an invoice for the toll and a $1.00 processing fee in about three (3) weeks. If the invoice is paid by the due date noted in the invoice no further action will be required.
  • 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 www.ezpassnh.com.
  • 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 tag programmed for the vehicle classification you use most frequently. You should never use your tag in a vehicle type other than the one you initially requested such as a car tag in a tractor-trailer.

  • I have an E-ZPass account with another toll agency. Will I get a discount on NH tolls if I use my transponder from another agency?
    • No. Only NH E-ZPass account holders using NH transponders will get a discount at NH tolls.
  • What discounts are offered to NH E-ZPass account holders?
    • The discount is based on the class of vehicle not the type of account. NH E-ZPass discounts for vehicle classes 1-4 is 30% and classes 5-12 is 10%.

  • 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.

    • NO. Only E-ZPass transponders are accepted in E-ZPass ONLY lanes.

    • If you fail to replenish your account when the balance gets low, and your actual balance drops below $0.00 due to usage of your transponder, you may be subject to an administrative fee of $25.00 in addition to amount of funds necessary to bring your account into compliance with the minimum balance requirements.
  • 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.
