How to Pay Tolls in Utah: Complete 2026 Guide to Payment Methods

Utah’s toll system runs on one main tool: the Express Pass transponder. Get one, load it with funds, and you’re set for every Express Lane on the I-15 corridor. Skip it, and you’re either looking at a traffic violation or a hefty rental car fee. Either way, knowing the rules upfront saves you money and headaches.

I’ve spent enough time on the Wasatch Front to say this confidently: Utah’s system is actually one of the cleaner toll setups in the country once you understand it. Let me walk you through everything you need to know for 2026.

What Toll Roads Exist in Utah Right Now?

Before you worry about payment methods, it helps to know exactly where tolls apply. Utah isn’t plastered with toll booths like some East Coast states, but the roads that do charge add up fast if you commute daily.

Utah’s tolling centers around the I-15 Express Lanes, a 72-mile High Occupancy Toll (HOT) corridor stretching from Spanish Fork in Utah County all the way to Layton in Davis County. This system is managed entirely by the Utah Department of Transportation (UDOT).

Here’s a quick overview of what’s currently tolled or managed:

The I-15 Express Lanes are divided into 16 payment zones (8 in each direction). You pay per zone based on the price displayed when you enter, and that price locks in for your current zone even if traffic gets worse while you’re driving. Pretty fair, actually.

The Only Way to Pay Utah Tolls: The Express Pass

Here’s the thing most people miss: Utah does not have a pay-by-mail or bill-by-plate system for its I-15 Express Lanes. If you drive through without an Express Pass, it’s classified as a traffic violation, not a missed payment. The fine starts at $337 in 2026. So this isn’t a “pay later” situation. It’s a “have your transponder or stay in the regular lanes” situation.

The Express Pass is a windshield-mounted RFID transponder that communicates with overhead gantry readers at highway speeds up to 75 mph. It runs on a prepaid debit model, meaning you load funds in advance and the system deducts tolls automatically as you pass through each zone.

You manage everything through the official Express Pass portal at expresspass.utah.gov.

How the Express Pass Transponder Works

The transponder itself is simple to use, but there’s one feature that catches people off guard: the manual toggle switch. This switch lets you tell the system whether you’re a solo driver paying a toll or a carpool using the lane for free.

Here’s how the two modes work:

TOLL Mode

• Slide the tab to the left until it clicks
• The word “TOLL” appears on the device
• The RFID signal activates and your account gets charged
• Required for all solo drivers

HOV Mode

• Slide the tab to the right
• “HOV” appears on a red background
• The signal deactivates so no charge applies
• Used when you have 2 or more passengers

Getting this wrong is a real problem. If you’re driving solo with the transponder set to HOV, that’s a violation. Double-check your setting before merging into the Express Lane every single time.

Installation: Where to Mount It

Placement matters more than most people realize. Incorrect mounting can cause read errors, which may result in a violation notice even if your account has plenty of funds.

Follow these guidelines exactly:

• Mount on the interior of the front windshield
• Position it at least 2 inches below the rearview mirror
• Keep it within 6 inches from the top of the windshield

Own an EV or plug-in hybrid? Many newer electric vehicles have electromagnetic shielding built into the windshield glass. This shielding can block the transponder’s 915 MHz signal. Check your owner’s manual for a designated “transponder window,” which is an unshielded area of the glass where the device will actually read correctly.

Who Pays and Who Rides Free

Not everyone using the Express Lanes owes a toll. Utah has a clear occupancy-based system, and understanding it helps you use the lanes correctly.

Important Change for EV Drivers in 2026

This one stings a bit if you bought an EV expecting toll-free perks. The federal Clean Vehicle Pass program, which previously allowed solo EV and alternative fuel vehicle drivers to use HOV lanes for free, expired on September 30, 2025.

Starting in 2026:

• Solo EV drivers must use an Express Pass in TOLL mode
• All former “C” decals and Clean Vehicle stickers are no longer valid
• UDOT has already cleared the Clean Vehicle application database

EV drivers now pay the exact same rates as everyone else driving solo. The good news is the rates are still reasonable if you use the lanes smartly.

Express Pass Costs and Account Setup

Setting up an account takes about 10 minutes. Before you start, here’s what the costs look like so there are no surprises:

That monthly maintenance fee is worth understanding. If you drive the Express Lanes regularly, you’ll never pay it because the fee waives automatically once your monthly tolls hit $2.50. If you use the lanes less than once a month, the $2.50 fee applies. Think of it as a light inactivity charge.

How to Open an Express Pass Account

Here’s the step-by-step process:

1. Go to expresspass.utah.gov and select “Open an Account”
2. Enter your full name, physical street address, and contact numbers
3. Create a password (must include uppercase letters, lowercase letters, and numbers)
4. Set a 4-digit PIN for account security
5. Choose and answer a security question from the available options
6. Enter your vehicle information and license plate
7. Select your transponder type (sticker mount or switchable)
8. Add a credit or debit card for automatic replenishment (PIN-only cards are not accepted)
9. Submit your order

Your transponder typically arrives with your initial $25 prepaid balance ready to use. Once it arrives, mount it correctly and you’re good to go.

How Toll Pricing Works on the I-15 Express Lanes

Utah uses dynamic pricing, which means toll rates change in real time based on traffic volume. The goal is to keep Express Lane speeds above 55 mph even when regular lanes are gridlocked. When more solo drivers want in, the price rises to manage demand.

The current pricing range for 2026 sits between $0.25 and $2.00 per zone. Here’s what that looks like in practice:

The price you see on the overhead sign when you enter a zone is the price you pay for that zone, full stop. If congestion spikes after you merge, your rate doesn’t change. That locked-in pricing is genuinely one of the better design choices in this system.

A Simple Way to Save Money

Check the price sign before the entry point. If it reads more than you’re comfortable paying, stay in the general lanes. The decision point comes before the solid double-white lines, and once you’re across them, you’re committed. Entry and exit are only legal at the dashed line sections, so plan your moves in advance.

Paying Tolls in a Rental Car

Renting a car in Utah? This is where things get a little annoying. Most major rental companies run their own toll programs using your license plate or a built-in transponder, and they charge administrative fees on top of the actual toll cost.

There’s a smarter option. You can use your own Express Pass in the rental car and avoid the rental company’s fees entirely. To do this properly:

1. Log into your Express Pass account
2. Add the rental car’s license plate temporarily
3. Make sure any built-in transponder already in the rental vehicle is shielded or turned off
4. Remove the rental plate from your account when you return the car

If you don’t do this and the rental car has its own transponder active at the same time as yours, you could end up getting charged twice. Read the rental agreement before you drive off.

The Adams Avenue Parkway: Utah’s Private Toll Road

Most of Utah’s tolling is handled through UDOT, but there’s one exception worth knowing about. The Adams Avenue Parkway in Ogden is a privately operated toll road that runs completely separately from the Express Pass system.

Key facts about the Adams Avenue Parkway:

• Does not accept Express Pass, E-ZPass, K-Tag, or any other regional transponder
• Accepts cash at the toll booth or a proprietary “ExpressCard”
• Charges $1.00 for a standard two-axle vehicle
• Adds $0.50 for each additional axle
• All vehicles must pass through a controlled booth, so missed tolls essentially don’t happen here

If you’re only driving I-15 Express Lanes, you’ll never encounter this road. But if you’re heading through Ogden, it’s good to know cash still works somewhere in Utah’s toll system.

Does Utah Accept E-ZPass or Out-of-State Transponders?

Short answer: no. Utah operates its own independent tolling system and is not part of the E-ZPass network. This surprises a lot of visitors coming from the East Coast, where E-ZPass covers dozens of states.

Utah’s Express Pass uses 915 MHz TDM technology, which differs from the protocols used in most other regional networks. As of 2026, ongoing negotiations for nationwide interoperability haven’t produced results yet. That means:

• E-ZPass does not work on I-15 Express Lanes
• PIKEPASS (Oklahoma) is not accepted
• K-Tag (Kansas) is not accepted
• SunPass (Florida) is not accepted

If you’re visiting Utah and plan to use the Express Lanes even once, set up a temporary Express Pass account before your trip or accept that you’ll be in the general lanes. There is no workaround here.

Watch Out for Toll Scam Texts

This section matters more than most people expect. A wave of “smishing” scams (SMS phishing attacks) has hit Utah drivers in recent years, and they’re getting more convincing.

These scams send text messages pretending to be UDOT or “Utah Toll Services,” claiming you owe an unpaid toll and asking you to click a link to pay immediately.

Here’s what UDOT actually does:

• UDOT does not send text messages requesting toll payments
• Utah’s Express Lanes are a prepaid system only
• There is no bill-by-plate system, so anyone claiming you owe a balance via text is running a scam

If you get one of these texts, ignore it and report it. Do not click any links. The official UDOT scam alert page has the full details and examples of what these fake messages look like.

What Happens If You Get a Violation Notice

Got a notice in the mail claiming a transponder violation? Don’t panic. This can happen even with an active account, typically due to a transponder malfunction or a low battery in the device.

Here’s how to handle it:

1. Locate Section C on the citation form
2. Fill in your transponder number (it begins with “026”)
3. Attach a copy of your Express Pass account statement showing you had sufficient funds at the time of the incident
4. Submit the form within the deadline shown on the notice

This process clears the violation in most cases. The key is acting quickly and keeping your account statements accessible. You can view and download your transaction history anytime through expresspass.utah.gov.

Ready to Hit the Road Without the Stress?

Utah’s toll system rewards preparation. Get your Express Pass set up before you need it, keep your balance above $20, and check the pricing signs before committing to an Express Lane entry. Do those three things and tolls become the smallest part of your commute.

The biggest lesson from all of this? Utah tolls are not a pay-later system. There’s no mailed invoice safety net for Express Lane use. Either you have a valid transponder in TOLL mode, or you stay in the free lanes. That’s the whole deal.
