Why this matters in Florida
Miami's key routes — the Dolphin (SR-836), Turnpike, Sawgrass, and I-95 Express — are cashless. If you drive an un-equipped car, the toll is captured by plate billing and passed to the rental company, who bills you back, frequently with an administrative fee (how that works).
The chain toll-program trap
National chains often enroll you in an all-or-nothing daily toll program — a flat daily fee for every day of the rental, whether you hit a toll or not, sometimes on top of the tolls. A week's rental with two toll trips can cost far more than the tolls themselves.
How iRent does it
- SunPass-ready cars — drive straight through every gantry.
- From $10.99/day, with monthly specials for long-term renters.
- Transparent billing — no surprise admin gouging.
Tips to keep tolls low
- Know your route — some trips have non-toll alternatives (US-1 vs. the Turnpike).
- For a long trip like the Keys or Naples, a transponder pays for itself.
- Renting a month? Ask about the monthly SunPass rate.
🛣️ Bottom line: a SunPass-ready car means you never think about tolls — and you skip the flat daily fees the big chains bundle in.
