If you're driving your own car you can buy a Sunpass Mini.
If your visit is in the next few weeks, be aware that the Sunpass system is having problems with tolls being applied to users accounts. No telling when the problem will be totally solved. It's a big mess!
Yes we leave on Friday and will be driving our own cars. So we have to buy a SunPass? That is the only option to pay for tolls?
Since the Miami area of the Turnpike is cashless, yes, a Sunpass is the only way to pay for the tolls. When you cross into Florida, stop at the Welcome Center rest stop and buy the Sunpass Mini there. It costs $4.95 but you then have to create an account online and add a minimum of $10 to the account.
I don't know if the present problems with the Sunpass website will let you create an account though. Maybe someone who has recently done so can chip in.
Can you create an account prior to buying the mini?
What happens if you go through a toll without a sunpass? Do you get a ticket or just a bill?
According to the FAQ on the Sunpass website, a transponder is not required to use the toll roads. It doesn't go on to explain but I think they then use "Toll By Plate" where the toll charge is sent to the registered owner of the vehicle. Read here:
But with the transponder you get a small discount on the tolls.
As for creating the account prior to buying the Mini, I don't know. But you can try and see if it lets you do so. The account, if it lets you, will be incomplete until you add the transponder number.Edited: 28 July 2018, 22:23
NO reason to get a Sunpass, just be certain that the registration and address match on the car you'll be driving. Toll-by-Plate will send you the bill for any tolls, be sure to avoid any "Sunpass" ONLY lanes/exits/Express Lanes.
You can also do toll by plate. No reason to buy a SunPass if you don’t want too. There is a small difference in the toll. Check out sunpass.com
