What MetroExpress Lane Pay is and how it works

MetroExpress Lane Pay is a toll payment system used on express lanes in the Dallas-Fort Worth area, primarily on Interstate 635 and the Dallas North Tollway. Instead of stopping at a booth, you pay electronically either through a transponder mounted on your windshield or by having your license plate photographed and billed later.

The system is operated by the North Texas Tollway Authority (NTTA). When you drive through an express lane, sensors read your transponder or capture your plate. If you have an active account, the toll is deducted automatically. If you don't have a transponder or account, NTTA photographs your license plate and sends you an invoice by mail.

Express lanes exist because they charge a variable toll — the price changes based on traffic volume. During heavy congestion, tolls are higher to manage demand and keep traffic flowing. During light traffic, tolls are lower. This is different from regular toll lanes, which charge a flat rate.

Key Takeaways

  • MetroExpress Lane Pay is the toll system for express lanes on I-635 and the Dallas North Tollway in the DFW area, operated by the North Texas Tollway Authority.
  • You can pay with a TollTag transponder (the fastest option) or by license plate invoice, which arrives by mail after you drive through.
  • Express lane tolls change throughout the day based on traffic — they are higher during rush hour and lower during off-peak times.
  • If you receive a toll invoice and don't pay it, NTTA can suspend your vehicle registration or report the debt to a collection agency.
  • You can set up an account online, by phone, or in person at an NTTA customer service center.

Getting a TollTag transponder

A TollTag is a small electronic device that mounts on your windshield and communicates with toll readers as you drive through. It is the most convenient way to use MetroExpress lanes because tolls are deducted automatically from your prepaid account, and you never receive a paper invoice.

You can order a TollTag online at ntta.org, by phone at 972-818-6882, or in person at an NTTA customer service center. There is no charge for the transponder itself, but you must set up a prepaid account with a minimum balance (the amount varies). You can use the same TollTag on multiple vehicles if you register them all to your account.

Once you receive your TollTag, mount it on the inside of your windshield in the location shown in the instructions. The transponder communicates best when placed correctly, so follow the positioning guidelines. You can then add funds to your account online, by phone, or through automatic replenishment, which charges your credit card when your balance drops below a set amount.

Paying by license plate if you don't have a TollTag

If you drive through an express lane without a TollTag, NTTA's cameras photograph your license plate. Within a few weeks, you will receive a toll invoice by mail at the address registered with your vehicle's title. The invoice shows the date, time, location, and toll amount.

You can pay the invoice online at ntta.org, by phone, or by mail. Payment is due within a set timeframe (check your invoice for the exact important date). If you pay promptly, there are no additional fees beyond the toll itself.

If you frequently use express lanes, getting a TollTag is usually cheaper and faster than paying invoices one at a time. However, if you use them only occasionally, paying by plate may be simpler because you don't need to maintain a prepaid account.

What happens if you don't pay a toll invoice

If you receive a toll invoice and do not pay it by the important date, NTTA can take several steps. First, they may send a second notice with a late fee added. If you still do not pay, the debt can be reported to a collection agency, which will appear on your credit report.

More importantly for vehicle registration, NTTA can place a hold on your vehicle registration renewal. When you try to renew your registration with the Texas Department of Motor Vehicles, the system will flag the unpaid toll debt and prevent renewal until you pay NTTA or set up a payment plan.

If you believe you received an invoice in error — for example, if your vehicle was stolen or if you were not the driver — you can dispute it. Contact NTTA directly with your explanation and any supporting documents. They have a process for reviewing disputes, though it may take several weeks.

Setting up and managing your MetroExpress account

Whether you use a TollTag or pay by plate, you can create an account on ntta.org to view your toll history, update payment methods, and manage multiple vehicles. An account is required to get a TollTag, but it is optional if you only pay invoices by plate.

When you set up an account, you will need your driver's license number, vehicle registration information, and a valid email address. You can add multiple vehicles to one account, which is helpful if you have more than one car or if family members drive your vehicle.

If you move or change your email address, update your account information so that future invoices reach you. If NTTA cannot deliver mail to your address, you may miss payment important date and incur late fees.

How express lane tolls are calculated

MetroExpress lanes use congestion pricing, which means the toll changes based on real-time traffic conditions. During peak hours — typically 6 to 9 a.m. and 3 to 7 p.m. on weekdays — tolls are highest because demand is greatest. During off-peak times, tolls are lower.

NTTA publishes current toll rates on their website and updates them regularly. You can check the rate before you drive, though the actual toll you pay depends on the exact time you enter the express lane. The system is designed to keep traffic moving by pricing out some drivers during the busiest times, which reduces congestion for those who choose to pay.

If you have a TollTag, you see the toll deducted from your account after you drive through. If you pay by plate, the invoice shows the exact toll charged. There are no hidden fees, though late payments may include additional charges.

Frequently Asked Questions

Can I use my TollTag from another state on MetroExpress lanes?

No. TollTags from other states (such as EZPass or FasTrak) are not compatible with NTTA's system. You must get an NTTA TollTag to use express lanes in the Dallas-Fort Worth area. If you live out of state but drive through DFW regularly, you can still pay by license plate invoice.

What if I drive through an express lane by accident?

You will still be charged the toll. If you do not have a TollTag, you will receive an invoice by mail. If you believe you entered the express lane by mistake, you can contact NTTA to dispute the charge, but you will need to explain the circumstances. Accidental use is not automatically waived.

Do I need a TollTag for regular toll lanes, or only express lanes?

TollTags work on both express lanes and regular toll lanes in the NTTA system. However, you can also pay regular toll lanes by plate. Express lanes require either a TollTag or plate payment — there is no cash option.

What happens to my TollTag if I sell my vehicle?

You should remove the TollTag from your vehicle before selling it. You can then transfer it to another vehicle you own by updating your account on ntta.org, or you can return it to NTTA. If you leave it on the vehicle, the new owner may use it, and tolls will be charged to your account until you report it missing.

Can unpaid tolls affect my driver's license?

Unpaid tolls can prevent you from renewing your vehicle registration, which may eventually lead to a suspended license if you drive with an expired registration. However, the toll debt itself does not directly suspend your license. Paying the toll or setting up a payment plan with NTTA will resolve the registration hold.
