Once you have your FasTrak transponder, simply mount it on the inside of your windshield and you’re good to go! When driving on the South Bay Expressway, just continue through the non-stop “FasTrak Only” lanes and your toll will be automatically deducted from your prepaid account. It’s that easy! You can check your FasTrak account balance on our Web site any time 24/7. And don’t forget to take your transponder with you when you travel to Orange County or the Bay Area. You can use your FasTrak transponder on any California toll facility that accepts FasTrak. Click here to see where FasTrak can take you!
Important Information about our Customer Service Center
In observance of Thanksgiving the Customer Service Center will be closed for both phone and walk-in customers on Thursday and Friday, November 26 and 27 . We will be open during normal business hours and will be happy to assist with inquiries on the next business day, Monday, November 30.
Cash-paying customers should also note that the Otay Mesa Toll Plaza will not have toll attendants on duty. Travelers should be prepared to use the automated cash and credit card machines to pay the toll - exact change is required. Please plan accordingly.
