The easiest way to update your contact information, vehicle information or billing information is by logging into your account. Keeping your account information current helps us provide you with excellent customer service.

What happens if I don’t keep my credit card current?

91 Express Lanes accounts are pre-paid accounts. If you set up your account with a credit card, your credit card will be charged each time your account requires additional funds. If your credit card declines or expires, we will be unable to replenish your pre-paid account balance. Your account may become ineligible for toll charges. Transactions will be processed as toll evasion violations, which are subject to penalties and collection action as required by law.

What if I get a new vehicle or get rid of a vehicle?

Log into your account to update your vehicle information and to purchase a new sticker transponder. Also, remove your old vehicle information and sticker transponder from your account to avoid paying future tolls on the vehicle. The sticker transponder is single use and cannot be moved to your new vehicle. A switchable transponder can be moved between vehicles.

What if I have a rental car?

You can use a switchable transponder in a rental vehicle by adding the plate number to your account online for the period of time you will have the vehicle. If you do not have a switchable transponder, log into your account to order one. If the plate is not listed on your account and the transponder is not read, the transaction will be processed as a toll evasion violation, which may be subject to penalties by the 91 Express Lanes and/or the rental company.

Why do you need my contact information?

Current contact information (address, email, phone) allows us to contact you with information about your account. Your email address will be used to provide account statements and automatic notices related to your account, including but not limited to notice of impending expiration of your credit card, notice of underpayment of a cash account, and/or notice of impending account closure due to under or non-payment.

FasTrak® Transponder

Why is a transponder required?

The 91 Express Lanes operates with a state-of-the-art electronic toll collection system which requires a FasTrak® transponder. This transponder-based system allows travel at free flow speeds without stopping to pay a toll.

To use the 91 Express Lanes, vehicles must have a properly mounted FasTrak® transponder associated with a pre-paid account.

Failure to have a properly mounted transponder while travelling on the 91 Express Lanes is a violation of the California Vehicle Code and may result in the issuance of a toll evasion violation notice or citation by the California Highway Patrol.

To view how to properly mount your transponder, click here.

Do I need a transponder for each of my vehicles?

Yes. Each vehicle travelling on the Express Lanes is required to have a properly mounted transponder. If you would like an additional transponder, you may request one by logging into your account. If you have an occasional use for a transponder in an additional vehicle, it is highly recommended that you add the plate to your account and obtain an additional set of adhesive strips so you can mount the FasTrak® Flex® switchable transponder in the additional vehicle prior to the time of travel.

Do I need a switchable transponder?

No, you do not need a switchable transponder to travel on the 91 Express Lanes or to receive the 3+ carpool discount.

If you plan to travel on the Los Angeles Metro Express Lanes, Express Lanes in the Bay Area, 15 Express Lanes in Riverside County and wish to receive a discount for carpooling, you will need a FasTrak® Flex® switchable transponder. Log into your account to purchase a switchable transponder.

Where can I use my transponder?

You can use your 91 Express Lanes FasTrak® transponder on any toll facility in California. The 91 Express Lanes exchanges information with the other toll operators within the state to provide you with seamless travel with a single account. If you wish to receive a carpool discount on an Express Lane other than the 91 Express Lanes, you will need a FasTrak® Flex® switchable transponder. Simply call the 91 Express Lanes customer service center at (800) 600-9191 to request a switchable transponder.

Where do I pay the toll?

Your toll is paid automatically. The toll system calculates your toll based on the time you entered the lanes and the segments travelled and is deducted from your account prepaid toll balance automatically.

Both the Orange and Riverside county segments have a toll point approximately midway through the segment. Your transponder will register at each segment. There is no place to stop and pay cash on the 91 Express Lanes.

What is the difference between Entry Time and Toll Point Time on my statement?

Entry Time is the time you viewed the toll price sign for each segment. It is used to determine the price that was displayed on the toll price sign and the price you are charged. Toll Point Time is when you cross each toll point in Orange County or Riverside County.

How do you know if I am carpooling?

When you have three or more occupants, you are required to drive through the HOV3+ lane at each toll point to receive the carpool discount. When you pass through the toll point, 91 Express Lanes staff and California Highway Patrol are on site to visually verify that your vehicle meets the 3+ requirement. Failure to comply with the carpool requirement could result in a citation from the CHP.

Can large trucks or vehicles towing trailers use the Express Lanes?

Unfortunately, no. The only oversized vehicles allowed on the 91 Express Lanes are motor homes and buses. Large trucks may not use the 91 Express Lanes for several reasons: (1) Caltrans has approved a maximum vehicle weight of 10,000 pounds for the 91 Express Lanes; (2) under California law, a variety of vehicles, including vehicles towing a trailer, and trucks with more than two axles, may only use the right two lanes of a four-lane limited-access highway such as the SR-91 freeway. Therefore, these vehicles may not use the 91 Express Lanes because there are only two lanes, and; (3) most larger trucks using the SR-91 freeway must stop at one of the weigh stations located near Weir Canyon Road, which is not accessible from the 91 Express Lanes. Therefore, trucks required to stop may not use the 91 Express Lanes.

As with larger trucks, California law limits vehicles towing trailers to the right two lanes of a four-lane limited-access highway such as the SR-91 freeway. Therefore, vehicles towing trailers may not use the 91 Express Lanes.

What if my car breaks down while I am in the Express Lanes?

Our first priority is your safety. We have free tow truck services available to assist you during most hours of operation. The Express Lanes tow trucks are clearly marked with “Express Lanes.” Our traffic management center keeps a close eye on the Express Lanes and dispatches help within minutes.

If you experience car trouble, pull as far left as possible and turn on your emergency flashers. If possible, move to an area where there is a widened shoulder. Call 911 and inform them of your issue and location.

Our tow truck operators are trained to provide either fuel or a tire change, if the conditions are safe. If the tow truck operator determines that the safest action is to tow your vehicle, you and your vehicle will be taken to a safe California Highway drop-off location. From the drop-off location, you can contact a private tow company.

Why isn’t there a direct connection to the I-15 North from the Express Lanes?

A connector from the 91 Express Lanes to the future 15 Express Lanes North is underway. The new connector is currently scheduled to open in 2023.
