Do I Need a TollTag for TEXpress Lanes? 2025 Update

Frequently Asked Questions
Can I avoid TEXpress Lanes completely?
Yes, you can always use the free general-purpose lanes on the same highways. TEXpress Lanes are optional premium lanes that provide faster, more predictable travel times for those willing to pay.
How does GoCarma HOV verification work?
GoCarma uses GPS and Bluetooth to automatically detect when 2+ people with the app are traveling together in TEXpress Lanes during peak hours. The 50% discount appears on your toll bill automatically - no pre-activation required.
Why do TEXpress Lane prices change?
Dynamic pricing adjusts rates every 5 minutes based on traffic demand to maintain 50 MPH minimum speeds. Higher prices during congestion encourage some drivers to use free lanes, keeping express lanes flowing smoothly.
Do motorcycles qualify for HOV discounts?
Yes, motorcycles automatically qualify for 50% HOV discounts during peak periods without needing passengers. Riders must have the GoCarma app and an electronic transponder to receive the discount.
What happens if I can't pay TEXpress Lane tolls?
NTTA handles all TEXpress Lane billing. Unpaid tolls result in ZipCash invoices at premium rates, followed by late fees, potential vehicle registration blocks, and vehicle bans for habitual violators.
Can children qualify for HOV without smartphones?
Yes, GoCarma provides free "Occupant Passes" - small Bluetooth devices that detect additional passengers. As long as the driver has the GoCarma app, families can qualify for HOV discounts when traveling with children.
