The short answer
This charge is from Alamo Rent A Car for toll roads used during your rental. By driving through a cashless electronic toll without paying, you were automatically enrolled in Alamo's TollPass program.
Why the charge is appearing now
An unexpected line item labeled ALAMO TOLL on your bank or credit card statement is an Alamo TollPass Charge billed by Alamo Rent A Car. When you drive an Alamo rental vehicle through a cashless toll lane or bridge without paying cash or mounting an active transponder, the overhead camera reads the vehicle's license plate. Alamo routes the toll transaction through its automated TollPass system instead of sending a physical traffic violation notice.
This charge almost always posts several weeks after you return the rental car. Municipal toll authorities frequently take between two and six weeks to process gantry data and send usage records to rental car fleets. Because of this billing delay, the toll fee never appears on your final counter receipt when you drop off the keys. The total amount on your statement covers the actual cash toll rates plus Alamo's daily TollPass convenience fee, which generally ranges from $3.95 to $5.95 for each calendar day you passed through a toll gantry.
Drivers are often surprised by an ALAMO TOLL entry because they believed their personal toll pass covered the route. If your personal transponder fails to register at an overhead gantry due to mounting issues or a dead battery, the toll agency snaps a photo of the rental car plate instead. That plate lookup triggers Alamo's automated billing system even if you intended to pay with your personal toll account.

The portal displays an itemized receipt showing the exact date and highway location of every toll event.

How can I avoid this in the future?
To avoid Alamo's daily convenience fees, you must either pay tolls with cash where available or properly mount and use your own personal electronic transponder.
I had my own transponder, why was I charged?
If your personal transponder was not detected by the toll gantry, the camera reads the rental car's license plate instead. You can dispute the charge on TollPassGo.com by providing a receipt from your personal toll account.
