Getting a SunPass for an Enterprise rental car is straightforward: you can use the built-in PlatePass transponder that comes with the vehicle, use your own personal SunPass transponder, or pay for individual tolls online afterward. The most common and convenient method is Enterprise's own program. When you rent a car in Florida, it's typically equipped with an automated toll system. As you drive through a SunPass or other electronic toll lane, the system reads the license plate and charges Enterprise, who then bills you for the toll amount plus a convenience fee per toll day.
It's critical to understand the fee structure. Enterprise doesn't charge a daily fee for having the transponder; instead, they charge a fee for each day you actually incur a toll. This can add up, so if you're extensive driving on toll roads, you might want to consider alternatives.
Option 1: Use Enterprise's PlatePass This is the default. You don't need to do anything to activate it. Just drive through the tolls. After your trip, you'll see the charges on your rental agreement.
Option 2: Use Your Personal SunPass If you already have a SunPass transponder, you can bring it and use it in the rental car. You must log into your SunPass account online and add the rental car's license plate and the rental period to your account before you drive through any tolls. This ensures the toll is charged to your account and avoids Enterprise's fees.
Option 3: Pay Tolls Online Post-Trip If you go through a toll without a transponder, you can usually pay it online within a few days through the official Florida Toll Pay system. However, if you miss the payment window, Enterprise will process it through PlatePass and charge you the toll plus their administrative fee.
| Toll Payment Method | Activation Required? | Potential Cost for a 7-Day Trip with $10 in Daily Tolls | Best For |
|---|---|---|---|
| Enterprise PlatePass (Default) | No | $70 (Tolls) + $35.70 ($5.10/day fee) = $105.70 | Short trips, infrequent toll use, convenience |
| Personal SunPass Transponder | Yes (Add plate to account) | $70 (Tolls) + $0 fees = $70.00 | Frequent Florida travelers who own a transponder |
| SunPass Mini Sticker | Yes (Purchase & register) | Longer trips, avoiding rental company fees | |
| Pay-By-Plate Post-Trip | No (Risk of missing deadline) | $70 (Tolls) + $0 if paid on time = $70.00 | Accidental single toll, disciplined travelers |
The bottom line is to decide before you hit the road. For most renters, the built-in PlatePass is fine for occasional tolls. For heavy toll road use, bringing your own transponder is by far the most cost-effective choice.

















Just use the car's built-in system. It's already on. When you go through a toll, it automatically charges Enterprise, and they'll bill your card later. It's super easy—no setup needed. Be aware they add a small service fee for each day you use a toll. If you're only hitting a couple of tolls the whole trip, it's not a big deal. If you're living on the highway, the fees can stack up.

The key is to avoid surprise fees. Enterprise's system is convenient but charges a per-day service fee on top of the tolls. If you have your own SunPass transponder from a previous trip, bring it! You can add the rental car's license plate to your account online before you drive. This way, all tolls go directly to your SunPass account, completely bypassing Enterprise's fees. It’s the best way to save money if you’re a frequent visitor.

I learned this the hard way on a business trip to Tampa. I assumed the tolls would be cheap. I got the bill later: the actual tolls were fine, but the daily "convenience fee" from Enterprise doubled the cost. My advice? If you don't have a transponder, consider a SunPass Mini at a pharmacy or grocery store for five bucks. Register it to your rental car's plate. It's a tiny upfront cost that saves you a lot compared to the rental company's fees. It feels good to be in control of the cost.

Compare your options based on your travel plans. Enterprise's PlatePass is a pay-per-use system with an added administrative fee. For a three-day trip with one toll day, it's negligible. For a week-long trip using tolls daily, the fees become significant. The most economical solution for extended travel is to use a pre-paid SunPass account, either with a portable transponder or a sticker. This requires a small amount of pre-trip but results in the lowest total cost by avoiding third-party service charges altogether.
