Navigating Colorado’s highways gets easier when you have a toll pass. Whether you’re a daily commuter or occasional traveler, having the right toll pass saves you time, money, and the hassle of unexpected bills in your mailbox. This guide will walk you through all the options for getting your Colorado toll pass, helping you decide which method works best for your situation.
What is ExpressToll and Why You Need It
ExpressToll is Colorado’s primary electronic toll collection system that works on all toll roads in the state. With an ExpressToll account, you’ll save more than 35% compared to license plate billing rates on roads like E-470, Northwest Parkway, and all CDOT Express Lanes (including I-25, I-70, US-36, and C-470).
The best part? Your ExpressToll now works beyond Colorado’s borders through the Central United States Interoperability Hub, covering Texas, Oklahoma, and Kansas too!
Online: The Fastest Way to Get Your Colorado Toll Pass
The quickest and most convenient option is signing up online at expresstoll.com. The entire process takes about 10 minutes and your account becomes active immediately.
Here’s what you’ll need to provide:
- License plate numbers for all vehicles you want on the account

- A valid email address
- Credit card for the initial $35 deposit (this goes toward future tolls)
The online process is streamlined and user-friendly. Once you complete registration, your transponder will arrive by mail in 7-10 business days, but your account works immediately via license plate recognition.

Understanding ExpressToll Account Costs
One of the biggest advantages of ExpressToll is its straightforward pricing structure:
| Fee Type | Standard Account | Notes |
|---|---|---|
| Setup fee | $0 | No activation charges |
| Monthly maintenance | $0 | No recurring fees |
| Initial deposit | $35 | Applied toward future tolls |
| Standard sticker transponder | FREE | One per registered vehicle |
| Switchable HOV3+ transponder | $18 | Optional, for carpool lane access |
The $35 initial deposit is not a fee—it’s prepayment for tolls that will be used as you drive toll roads. Your account is automatically replenished when the balance gets low.
