If you receive a red light at the toll booth, and/or a message such as, "Call E-ZPass," "Low Balance" or "Toll Not Paid" it could be due to one or more of the following:

• Incorrect mounting of your transponder
• Sticker tag instructions
• Complete Pass instructions
• E-ZPass and Horizon instructions
• Inappropriate speed at the toll booth - your transponder may not read if your speed is above the posted speed limit (learn more about speeding through tolls)
• Inclement weather - specifically snow can cover externally mounted transponders, as well as toll booth readers. Radio signal interruptions can also happen due to weather
• Faulty toll reader at the toll booth - some of the toll booth readers are old and worn and don't work as efficiently as others
• The age of the transponder - internally mounted(windshield) E-ZPass transponders have a typical shelf life of three to five years. Externally mounted transponders, such as a plate or roof mount, have a typical shelf life of two to three years 
• Obstruction of transponder - a metal visor, GPS, window tint, etc. can cause alter/disrupt the signal
