Navigating the scenic byways and bustling highways of Colorado is an essential part of any visitor’s experience. From the majestic Rocky Mountains to the vibrant urban centers like Denver and Colorado Springs, the state offers a diverse range of landscapes and attractions. To ensure a smooth and efficient journey, understanding how to manage toll roads is paramount. This guide will detail where and how to acquire a Colorado Toll Pass, often referred to as a *Go–Pass or *ExpressToll* account, enabling you to traverse these routes without interruption.
Understanding Colorado’s Toll Road System
Colorado utilizes a modern and expanding toll road network, primarily managed by the Colorado Department of Transportation (CDOT). These toll roads are designed to alleviate traffic congestion, fund infrastructure improvements, and provide faster travel times, especially on heavily trafficked corridors. The most prominent of these are the express lanes found on major interstates.

Key Toll Road Corridors
- E-470: This is a 76-mile toll highway that encircles the Denver metropolitan area, providing a vital alternative to I-25 and other surface streets. It connects Denver International Airport with the southern and western suburbs. E-470 is entirely a toll facility, meaning every vehicle using it incurs a toll.
- Northwest Parkway: Extending west from E-470, this toll road further connects motorists to Broomfield and beyond, offering another crucial artery for traffic in the northern Denver metro area.
- Interstate 70 (I-70) Express Lanes: Significant sections of I-70, particularly through the Denver metro area and approaching the mountain communities, feature express lanes that operate on a dynamic tolling system. These lanes offer a premium travel experience with potentially reduced travel times.
- Central I-70: The Central 70 Project has transformed a section of I-70 in Denver, introducing express lanes managed by ExpressToll.
- C-470 Express Lanes: Sections of C-470, a southern beltway around Denver, also incorporate express lanes that utilize dynamic tolling.
Types of Tolling
Colorado employs an all-electronic tolling system. This means there are no toll booths to stop at. Instead, your license plate is photographed, and a toll is assessed. For account holders, the transponder (or License Plate Account) ensures the lowest toll rate. For those without an account, a bill will be sent to the registered owner of the vehicle, often at a higher rate.
Acquiring Your Colorado Toll Pass (ExpressToll Account)
The most convenient and cost-effective way to use Colorado toll roads is by setting up an ExpressToll account. This account allows you to manage your tolls electronically, receive discounted rates, and avoid potential penalties for missed payments.
The Online Portal: The Primary Method
The most straightforward method for obtaining your Colorado Toll Pass is through the official ExpressToll website.
- Visit the ExpressToll Website: Navigate to the official ExpressToll website. This is the central hub for all account management, including setting up new accounts, replenishing balances, and viewing toll history.
- Create an Account: Look for an option such as “Open an Account” or “Sign Up.” You will be prompted to provide necessary information, including:
- Contact Information: Name, address, phone number, and email address.
- Vehicle Information: License plate number(s), make, model, and year for each vehicle you intend to use on toll roads.
- Payment Information: A valid credit card or debit card is required for automatic replenishment.
- Choose Your Transponder Option:
- Free-Moving Transponder: ExpressToll offers a windshield-mounted transponder that communicates with tolling gantries. This is typically provided free of charge when you open an account and maintain a sufficient balance.
- License Plate Account: If you prefer not to have a physical transponder, you can opt for a License Plate Account. In this case, ExpressToll links your license plate number to your account. This option may have slightly higher toll rates compared to using a transponder.
- Fund Your Account: An initial deposit is required to establish your account. This deposit varies but ensures you have funds to cover tolls. You will need to set up automatic replenishment so that your account is automatically topped up when your balance falls below a certain threshold. This prevents your account from becoming inactive and avoids potential toll violations.
- Receive Your Transponder (if applicable): If you choose the transponder option, it will be mailed to you within a few business days. Instructions for installation and activation will be included. Ensure you install it correctly in your vehicle’s designated windshield area for proper functioning.
Phone and In-Person Options
While the online portal is the most common and efficient method, ExpressToll also offers alternative ways to set up your account.

- By Phone: You can call the ExpressToll customer service line to set up an account over the phone. Have your vehicle information and payment details ready. This is a good option for those who are less comfortable with online processes.
- In Person (Limited Locations): Historically, there have been limited in-person service centers. It is advisable to check the ExpressToll website for the most current information on service center availability and locations. These locations may offer assistance with account setup, transponder issues, or payment inquiries.
Temporary Visitors and Out-of-State Vehicles
For tourists and visitors driving vehicles registered outside of Colorado, understanding the tolling system is crucial to avoid unexpected charges.
Using Toll Roads Without an Account
If you are visiting Colorado for a short period and do not wish to set up an ExpressToll account, you have a couple of options:
- Pay by Plate (Billed Tolls): When you use a toll road without a transponder or an active License Plate Account, your license plate will be photographed. CDOT will then mail a toll bill to the registered owner of the vehicle.
- Timeliness is Key: These bills are typically sent within a few weeks. It is imperative to pay these bills promptly upon receipt.
- Higher Rates: Be aware that Pay by Plate rates are generally higher than those for account holders.
- Out-of-State Considerations: If your vehicle is registered out of state, the bill will be sent to your registered address. Ensure your mailing address on file with your state’s Department of Motor Vehicles is current.
- Setting up a Limited Account: For visitors who plan to use toll roads multiple times during their stay, it might still be beneficial to set up a temporary ExpressToll account. This can be done online and requires a credit card for payment. You can often link your rental car’s license plate if you are aware of it beforehand, or manage it as a guest user.
Rental Cars
If you are renting a vehicle in Colorado, the rental company will likely have a policy regarding toll roads.
- Rental Company Toll Programs: Most major rental car agencies (e.g., Hertz, Enterprise, Avis) offer their own toll payment programs. When you rent a car, you may be automatically enrolled, or you can opt into their service.
- Automatic Billing: These programs typically link your rental agreement to your credit card, and the rental company will pay the tolls incurred on your behalf, then charge your credit card for the tolls plus an administrative fee.
- Understand the Fees: It is crucial to understand the rental company’s toll fees, as they can sometimes be higher than setting up your own ExpressToll account, especially if you only use a few toll roads. Always ask about their toll policy at the time of rental.
- Direct Billing: Some rental companies might pass through the Pay by Plate billing directly to you, so clarify this beforehand.
Managing Your ExpressToll Account and Avoiding Violations
Once you have your Colorado Toll Pass or account, consistent management is key to a seamless experience.
Account Maintenance
- Monitor Your Balance: Regularly check your account balance through the ExpressToll website or app. Ensure your automatic replenishment is functioning correctly.
- Update Vehicle Information: If you add or remove vehicles from your household, or if your license plate changes, update your vehicle information immediately within your ExpressToll account. Failure to do so can result in improper toll assessment or violations.
- Keep Payment Information Current: Ensure your credit card or debit card on file is up-to-date and has not expired.

Toll Violations
- What Constitutes a Violation: A toll violation typically occurs when a toll is incurred but not paid within the designated timeframe. This can happen if your ExpressToll account is inactive due to insufficient funds, incorrect vehicle information, or if you use a toll road without any payment arrangement.
- Consequences: Toll violations result in penalties, which can be significant. These penalties are in addition to the original toll amount. Repeated violations can lead to further actions by the state.
- Disputing a Violation: If you believe you have received a violation in error, contact ExpressToll customer service immediately to understand the process for disputing the charge. Provide any supporting evidence you may have.
By understanding the systems in place and taking the simple step of acquiring and maintaining an ExpressToll account, your travels through Colorado’s dynamic toll road network will be efficient, stress-free, and cost-effective, allowing you to focus on the breathtaking scenery and vibrant experiences the Centennial State has to offer.
