A Florida-accepted transponder is required to use I-4 Express. If you enter I-4 Express without a transponder in your vehicle, SunPass, the tolling authority on I-4 Express, will capture your license plate and send a bill in the mail to the address to which your vehicle is registered. The SunPass bill will include a $2.50 administration fee plus the total cost of all tolls through which you drove. No action is required until you receive the bill. For questions about the billing process, contact SunPass at 1-888-865-5352.

Many rental car companies offer renters an optional toll transponder. If you choose the optional transponder, the company will charge you for the tolls you incur while driving the rental vehicle. If you do not have a transponder in your rental vehicle and choose to use I-4 Express or enter by accident, the rental car company will charge you for the tolls and fees you incurred while driving the vehicle. If you have any questions about the toll billing process, please contact your vehicle rental company.

Since I-4 Express opened, both safety and efficiency have improved:

• Vehicle crashes have decreased 42% since the express lanes opened.

• In addition to the benefits for express lane users, travel times have improved in the general use lanes. The average motorist saves 4 or more minutes on their trip — adding up to 2 hours a month for a regular commuter.

• Travel speeds in the general use lanes have increased by 5 mph on average in the morning and 8 mph on average in the afternoon.

• Lane-blocking incidents on I-4 have dropped 58% since the opening of I-4 Express.

The managed lanes, known locally as I-4 Express, are in the middle of I-4 separated from the rest of traffic by a concrete barrier wall. I-4 Express begins at mile marker 75, just west of Kirkman Road in Orange County, and continues for 21 miles to mile marker 95, just east of State Road 436 in Seminole County.

The posted speed limit on I-4 Express is 60 miles per hour.

I-4 Express is physically separated from the non tolled general use lanes by concrete barrier walls with limited access points allowing drivers to merge in and out of the managed lanes.

Tolls regulate the number of vehicles traveling on I-4 Express, which manages the congestion in those lanes. Tolls help ensure that motorists get the experience they are paying for.

Vehicles with two axles are allowed in I-4 Express. Vehicles with three or more axles are not allowed unless they are designated emergency vehicles. Examples of vehicles with three or more axles may include trucks, large recreational vehicles (RVs) and vehicles pulling trailers.

Two kinds of ramps provide access to I-4 Express. There are 14 I-4 Express entrance and exit ramps where motorists can safely merge between I-4 general use lanes and the managed lanes. There are 14 I-4 Express direct connect ramps that allow direct access to and from I-4 Express via surface streets such as South Street in downtown Orlando or Central Parkway in Altamonte Springs. View a map of I-4 Express and see which ramps are available for your next trip.

I-4 Express access points are limited to improve traffic flow by reducing the number of vehicles entering and exiting the roadway. I-4 Express serves longer drives, freeing up capacity in the general use lanes for other motorists.

Depending on your destination, you may need to exit I-4 Express before you get to the main interchange. In some instances, you may need to continue past your destination and double back.

If you miss your exit from I-4 Express, do not stop. Continue to the next exit.

If you unintentionally enter I-4 Express, do not stop. Continue to the next exit. Refer to “How do I pay if I enter I-4 Express by accident or without a transponder” for more information.

Transit buses, school buses, and vanpools that register through Express Bus Registration may have I-4 Express tolls waived. Buses and van pools must renew their registration annually.

Tolls are collected electronically via any of the nine Florida-accepted transponders: SunPass, Peach Pass, LeeWay, NC Quick Pass, E-ZPass, E-PASS, PIKEPASS, KTAG and TollTag. Others may be added in the future. There is no cash or TOLL-BY-PLATE option.

Tolls are not fixed; they vary based on traffic conditions in I-4 Express. Overhead signs guide motorists in and out of access points and display the current toll.

Drivers should review the signs before entering I-4 Express and during their trip to help decide whether to exit or to continue on I-4 Express. Drivers will never be charged more than the toll that was shown on the sign when they passed it. If the toll changes after passing the sign, drivers will pay the lower amount.

Per Florida Statute, if a customer's average travel speed for a trip in an express lane falls below 40 miles per hour, the customer will be charged the minimum express lane toll.

Overhead signs display destinations and the toll to get to each destination.

There are multiple decision points along the 21 miles of I-4 Express. Motorists in the managed lanes will only pay for the portions of I-4 Express they drive. Before each entrance, you’ll see two overhead signs displaying the current tolls for up to three destinations. Don’t see your exit? It might fall between the exits listed on the sign or you might see it on another overhead sign later during your trip. On I-4 Express, the first two destinations listed on the pricing sign are the most popular destinations from your entry point. The third destination is the farthest distance you can travel on the lanes from your entry point.

Toll amounts are displayed on the overhead signs before entering so drivers have time to decide to use I-4 Express or travel in the non tolled general use lanes. Please visit SunPass.com to view your current activity and toll charges for I-4 Express. If you use another Florida-accepted transponder, visit your provider’s website (E-PASS, E-ZPass, LeeWay, NC Quick Pass, Pike Pass, KTAG ,TollTag,Peach Pass) to view your activity and toll charges.

I-4 Express was designed to operate with dynamic tolling, which helps prevent congestion and maintain reliable travel times for motorists. Dynamic tolling has been implemented successfully to maintain target speeds on other managed lanes in Florida.

With dynamic tolling, the posted tolls on I-4 Express will be adjusted throughout the day as needed, by travel segment, with the goal of keeping vehicles moving to maintain a reliable trip. As more vehicles enter a segment of I-4 Express, the toll for that segment will increase. Motorists on I-4 Express will continue to pay only for the distance they drive.

Overhead electronic signs will display the current toll for each segment. Drivers should review the signs before entering I-4 Express and during their trip to help decide whether to exit or to continue on I-4 Express.

The maximum amount is capped at $3 per segment, but based on traffic data, tolls are not expected to rise significantly upon transitioning to dynamic tolling. The toll for each segment of I-4 Express will increase or decrease at 15-minute intervals based on the traffic volume in that segment. Tolls will be based solely on the amount of traffic in the express lanes.

I-4 Express provides drivers with travel choices, improves safety, enhances mobility for all motorists, minimizes delays, offers more predictable travel times, and reduces fuel consumption.

No, I-4 Express benefits all drivers on I-4. Every car in a managed lane is one fewer vehicle in the general use lanes, meaning less congestion for everyone.

Tolls regulate the number of vehicles traveling on I-4 Express, which manages the congestion in those lanes. Tolls help ensure that motorists get the experience they are paying for.

There are various types of managed lanes, including express lanes and high-occupancy vehicle (HOV) lanes, both of which are in use in Florida. Florida’s various express lanes systems in use across the state all operate on the same principle of varying tolls to manage demand, but there are certain operational differences among them.

Managed lanes, and specifically express lanes like I-4 Express, are a highway within a highway that use differing toll rates to manage demand for the lanes. Toll roads are stand-alone highways that typically use a fixed toll rate.
