Do I Need to Use I-4 Express? 2025 Update
No, I-4 Express lanes are optional - but they offer a faster, more reliable route through Central Florida's most congested corridor. I-4 Express comprises two express lanes in each direction in the center of Interstate 4, designed to maintain speeds of at least 50 mph even during peak traffic periods.
Critical Requirement: You MUST have a transponder to use I-4 Express. There is no cash or toll-by-plate option. A $25 toll violation plus the cost of tolls will be imposed on drivers who don't have an interoperable transponder.
2025 Update: Dynamic tolling began February 24, 2025. Tolls now adjust every 15 minutes based on real-time traffic conditions, with prices displayed on electronic signs at every entry point.
I-4 Express Toll Costs: Dynamic Pricing
I-4 Express uses dynamic tolling where prices fluctuate based on real-time traffic demand. The more people using the lanes during peak times, the higher the toll. When traffic is light, tolls decrease to encourage usage.
Current Dynamic Toll Structure (2025)
| Pricing Model | Minimum Rate | Maximum Rate | Full Trip Cost |
|---|---|---|---|
| Per Segment | $0.50 | $3.00 | Variable by destination |
| Full Length (21 miles) | ~$3.50 (off-peak) | ~$21.00 (maximum peak) | Universal to Sanford area |
| Previous Fixed Rate (Pre-2025) | $0.50/segment | $0.50/segment | ~$3.50 maximum |
Peak vs Off-Peak Pricing
Highest Toll Periods:
- Morning rush: 6:00-9:00 AM weekdays
- Evening rush: 3:00-7:00 PM weekdays
- Busiest segments: Near downtown Orlando show "small increases"
Lower Toll Periods:
- Mid-day hours (10:00 AM - 2:00 PM)
- Evening hours (7:00 PM - 10:00 PM)
- Weekends (generally lower demand)
- Late night/early morning (10:00 PM - 6:00 AM)
How Dynamic Pricing Works
Roadside equipment monitors traffic in the managed lanes and toll prices periodically adjust to maintain free-flowing travel. Signs display destination and toll amounts in advance of every I-4 Express entry point. When a driver passes under a toll amount sign, the toll rate is locked in for the destinations shown.
Key Features:
- Prices update every 15 minutes based on traffic volume
- Drivers pay the price displayed when they enter, even if it increases later
- Maximum $3 per segment cap prevents excessive pricing
- FDOT guarantees minimum 50 mph speeds or minimum toll charge applies

- Quicker clearance times reduce the risk of secondary crashes
Traffic Flow Benefits
General Lane Improvements:

Usage Statistics
Since opening, FDOT said it has taken less than three years for the I-4 Express Lanes to record 50 million trips. The Express lanes have generated $71.4 million in gross toll revenue since they opened in 2022, paying down the cost of the entire I-4 Ultimate Project and funding operation and maintenance costs.

Frequently Asked Questions
What happens if I accidentally enter I-4 Express without a transponder?
Don't panic and don't stop or back up. Stay in the right lane and exit at the next merge point. You'll receive a $25 violation fee plus the cost of tolls, which you can resolve through the turnpike customer service line.
How high can I-4 Express tolls go with dynamic pricing?
The maximum is $3 per segment, meaning it could theoretically cost up to $21 to ride the full 21-mile length during peak congestion. However, FDOT stresses they don't expect tolls to reach the maximum very often.
Can I use my out-of-state E-ZPass on I-4 Express?
Yes, E-ZPass from any participating state works on I-4 Express. The system also accepts transponders from other states including Peach Pass (Georgia), NC Quick Pass (North Carolina), and others listed in the accepted transponders section.
What happens if speeds drop below 50 mph in I-4 Express?
FDOT guarantees that if your average speed falls below 40 mph while using the express lanes, you will only be charged the minimum toll, per state statute. This ensures you get value for the premium pricing.
Can large RVs or vehicles towing trailers use I-4 Express?
No, I-4 Express is limited to two-axle vehicles only. This excludes large RVs, trucks with three or more axles, and any vehicle pulling a trailer, boat, or camper.
