What does this mean for car hire?  In most instances, the rental car companies such as, Alamo, Dollar, Budget, Avis, and National have signed up to Toll-by-Plate.  This is quite a simple system, in essence, you travel through the e-toll which is often called a Sun Pass or EZ Pass lane, and if you don t have a transponder in your car the toll booth just takes a photo of your number plate, this is then matched up with the rental car company and billed european car rental to your card.
Tolls can take a few days to reach your account so you may find that you have been billed after you actually dropped off the car, but that is normal.  There is an administration charge for this facility and this does vary according to which supplier european car rental you have chosen.  These are the current rates in Florida, other states may vary:
You don t have to use E-tolling in areas where it it is not yet mandatory you can still pay by cash.  But, if you have been through an E-toll once and activated the facility to your rental, then you will still have to pay the facility charge plus that toll even if you pay by cash for all the others.
One cautionary note: Many cars within the Budget fleet actually european car rental now carry a e-toll transponder that communicates directly with the e-toll. european car rental  This is fine if you are happy to use the system but if you don t want to use the system and want to pay all your tolls by cash then you must insist upon a vehicle that does not contain a transponder.
european car rental Regular travellers may want to consider obtaining either a Sun Pass or EZ Pass transponder of their own.  There are portable units available from service plazas on toll roads Publix in Florida sells portable Sun Pass transponders for $25.  Once purchased, you set up an online account, linking the account to a credit card for top-ups and then you can register european car rental your rental car to the account for the exact times and dates that you have the car.  This way, if any toll goes astray (and gets billed by the rental company) you can show proof that the car was registered to your account at the time.

There are many toll exit booths, particularly in Central Florida around Orlando and Kissimmee, which are dual purpose cash/e-toll.  If you have a transponder in the car this may automatically activate, even if you pay by cash and we have received a few complaints from clients who have been caught out this way. Please remember, if you are in any doubt, ask for a car without a transponder!!
