That's the system working the way it is intended to... the way you *usually* want it to.

When our device has not worked correctly (dead battery I think) and we drove through a toll lane we did not get penalized for not paying the toll. Instead, the system looked up our plate to see if we had a registered account. Finding that we did, it billed the account just as if the device had worked. That's the way we wanted it to work to avoid any penalty.

If you register a rental plate to your account but neglect to unregister the plate when you return the car, the system still works the same way. The next time the car is driven through a toll lane it will look up the plate, find your account, and bill that account. The system doesn't know that you no longer own that car until you tell it.

Did you have a Sunpass or an E-Zpass?

I have an E-ZPass and it didn't register (low battery) last time I was in Orlando. I got an invoice from Sunpass for the full tolls plus an administrative fee of $2.50.

The low battery issue was with an E-ZPass in MD. I haven't had a problem (yet) with the SunPass or SunPass-Pro here in Florida.

You can enter a starting and ending date and time when entering license plates into the SunPass system.

Check with the rental car company- they may require the charge they told my son that.
If you bring your ezpass that might solve it if you can show it to them at the counter.

I have both. Why would you say ezpass is better? Is ezpass accepted everywhere in Florida?Thank you

Here ya go:

Difference Between SunPass and E-Pass | Difference Between

E-Pass is not E-ZPass.

E-Pass is an alternative to SunPass and works only in the FL/GA area.

E-ZPass is the device that works in the northeast (MD, DE, PA, NJ, NY, etc)

Ahh good point. Maybe this one would be better (below Miami Herald article).

Either way, I'm a big fan of the UniPass.. When you see the map of tollroads covered by UniPass and notice that Connecticut, Vermont, Tennessee, Alabama, and Mississippi, and South Carolina are excluded, keep in mind that neither Tennessee, Mississippi, nor Connecticut have toll roads, and Alabama has no toll roads, but it does have four (4) toll bridges.

South Carolina has only one, The 17.7 mile Southern Connector (Interstate 185) in Greenville County. Greenville Co is north-west of Columbia, and sits about halfway between Atlanta, GA and Charlotte, NC. Should you need to use that road, it requires the not-used-anywhere-else Palmetto Pass, according to Wikipedia.

So, with UniPass, on the east coast you are really only screwed out of Vermont. Not a huge loss, I think very few Villagers make their way up to Vermont with any regularity.

UniPass is on Amazon or other various sales outlets for about $15.00. It has suction cups so you can move it from car to car. Just gotta go onto their website and pre-load it with a few bucks. I did $10. There are no monthly account maintenance or minimum usage fees. If you move it from one car to another (including a rental), you gotta just go online or the app and remove one car and add the new one. It only holds one car at a time. I would rather it did two or three (for family use), but they didn't ask me. People rarely do, lol.

MiamiHeraldSunpass&EZPass.

I learned the hard way.
Year+ ago flew into Orlando Sanford, late arriving, rented car from Dollar.
Counter person made no mention about tolls.
Drove to them, thinking could pay cash, no way.
Ended up bringing charged by the rental car co. $9.95 extra penalty fee for EACH toll.
Able to negotiate a lower settlement, but still costly!
Morale of this, is; bought Epass and have used it easily not only in FL, but thru IL, as well.
Can fund in $10. increments. Can do all, including buying pass on-line.
Get the pass and avoid the hassle!!
