What if I have a transponder from The Toll Roads and another state’s transponder?

North Texas: Since The Toll Roads partner with NTTA to provide our accountholders with compatibility on toll facilities in North Texas, we ask that you only have one account with The Toll Roads or NTTA to avoid being double charged. *At this time, accounts with NTTA cannot be used on The Toll Roads to pay tolls per California legislation. 

Other States: We do not recommend having multiple toll accounts that overlap the same area or region to avoid double charges or confusion on account charges.
