How 405 Express Lanes violations work and what they cost

A 405 Express Lanes violation occurs when you drive in the express lanes on Interstate 405 in Los Angeles without a valid FasTrak transponder, with an inactive transponder, or without meeting the occupancy requirement for your vehicle class. The violation is issued by the Los Angeles County Metropolitan Transportation Authority (Metro), not by the California Highway Patrol, and results in a notice sent to the vehicle's registered owner.

The base penalty for a first violation is $25, but the total bill depends on when you pay. If you pay within 21 days of receiving the notice, you pay the base penalty only. If you wait longer, late fees and administrative costs accumulate. A second violation within 12 months raises the base penalty to $50, and a third or subsequent violation within 12 months increases it to $100, plus applicable late fees.

Metro issues these violations through automated camera systems that photograph license plates and through manual enforcement by Metro officers. The notice arrives by mail at the address on file with the Department of Motor Vehicles, typically within two to four weeks of the violation.

Key Takeaways

  • A 405 Express Lanes violation is issued by Metro when you use the lanes without a valid, active FasTrak transponder or without meeting occupancy requirements, and the notice arrives by mail to your vehicle's registered address.
  • The base penalty is $25 for a first violation, $50 for a second within 12 months, and $100 for a third or more within 12 months, but late fees explore if you do not pay within 21 days.
  • You can contest the violation by requesting a hearing within 21 days of the notice date, and Metro will review the camera evidence or officer report before making a final decision.
  • Paying the violation does not affect your driving record or insurance rates, because it is a civil toll violation, not a traffic citation.
  • If you plan to use the 405 Express Lanes regularly, obtaining a FasTrak transponder costs nothing to set up and can be linked to a prepaid account or your credit card.

Who issues 405 Express Lanes violations and why

Metro operates the 405 Express Lanes as a toll facility and is responsible for collecting tolls and enforcing the rules of use. The express lanes run roughly 10 miles on I-405 between the I-10 junction and the Ventura County line, and are open to carpools, motorcycles, and solo drivers with active FasTrak transponders during peak hours.

Metro uses two enforcement methods: automated license plate readers mounted on overhead gantries photograph every vehicle entering the lanes, and Metro officers conduct manual patrols. When a vehicle without a valid transponder or with an inactive transponder is detected, Metro's system generates a violation notice. The same applies to vehicles that do not meet the occupancy requirement—for example, a solo driver in a regular sedan during hours when only carpools and motorcycles are permitted.

Metro issues violations because toll evasion reduces revenue needed to maintain the lanes and because the occupancy rules are designed to manage traffic flow and encourage carpooling. The violation is a civil matter, not a criminal one, and does not appear on your driving record.

What the violation notice contains and what it means

The notice you receive by mail will include the date and time of the violation, the location on I-405 where it occurred, a photograph of your vehicle's license plate (usually from the overhead camera), and the base penalty amount. It will also state the important date to pay or contest the violation, which is typically 21 days from the notice date.

The notice explains that you have three options: pay the penalty, request a hearing to contest it, or do nothing and face additional collection action. If you choose to pay, the notice includes instructions for paying online through Metro's website, by phone, or by mail. The payment address and phone number are printed on the notice itself.

The notice does not indicate whether this is your first, second, or third violation within 12 months. You will only learn the penalty tier when you receive the notice. If you have received multiple violations, each notice will reflect the appropriate penalty level based on Metro's records.

How to contest a 405 Express Lanes violation

To contest a violation, you must request a hearing in writing within 21 days of the notice date. The notice includes a form or instructions for submitting a hearing request. You can request a hearing by mail, online through Metro's website, or by phone, depending on the options listed on your specific notice.

When you request a hearing, you should explain why you believe the violation was issued in error. Common reasons include: the transponder was active but malfunctioned, you were in the correct vehicle class (carpool with sufficient occupants), the photograph does not clearly show your vehicle, or you were not driving the vehicle at the time. Include any supporting evidence, such as a receipt showing your FasTrak account was active, a photo of your passengers, or proof that someone else was driving your vehicle.

Metro will schedule a hearing, typically conducted by phone or video conference, within 30 to 60 days of your request. A Metro hearing officer will review the camera evidence, your statement, and any documents you submit. The officer will then issue a written decision upholding, reducing, or dismissing the violation. If the violation is upheld, you will receive a new notice with the final penalty amount and a important date to pay.

If you disagree with the hearing officer's decision, you may have the right to appeal to a higher level within Metro, though this process varies. Check your hearing decision notice for appeal instructions and important date.

Consequences of not paying or contesting a violation

If you do not pay the violation and do not request a hearing within 21 days, Metro will send a second notice indicating that the violation is now delinquent. Late fees and administrative costs will be added to the original penalty. The total amount owed will increase over time as additional collection fees accrue.

If the account remains unpaid, Metro may refer the debt to a collection agency or pursue other collection methods. In some cases, Metro can report the unpaid violation to credit bureaus, which can affect your credit score. Metro may also place a hold on vehicle registration renewal through the California Department of Motor Vehicles, preventing you from renewing your registration until the violation is paid.

Unlike a traffic citation, an unpaid 405 Express Lanes violation does not result in a suspended license or criminal charges. However, the registration hold can prevent you from legally driving the vehicle until the debt is resolved.

Getting a FasTrak transponder to avoid future violations

A FasTrak transponder is a small electronic device that mounts on your windshield and communicates with the overhead readers on the 405 Express Lanes. When you drive through the lanes with an active transponder, the system deducts the toll from your prepaid account. There is no charge to obtain the transponder itself.

To get a FasTrak transponder, visit the Metro website or call the FasTrak customer service line. You will need to provide your vehicle information and set up a prepaid account. You can fund the account with a credit card, debit card, or bank account. Tolls on the 405 Express Lanes vary by time of day and traffic conditions, typically ranging from $0.50 to $1.50 per trip during peak hours, though the exact amount changes dynamically.

Once your account is active and your transponder is mounted, you can use the express lanes during permitted hours. If you are a carpool or motorcycle, you may be able to use the lanes during all hours they are open. If you are a solo driver, you can use them during off-peak hours when tolls are lower or during peak hours by paying the toll. Make sure your account stays funded to avoid violations from an inactive transponder.

Differences between 405 Express Lanes violations and traffic citations

A 405 Express Lanes violation is fundamentally different from a traffic citation issued by the California Highway Patrol or local police. A violation is a civil matter—a debt owed to Metro for toll evasion—while a traffic citation is a criminal or quasi-criminal matter that can affect your driving record and insurance rates.

Because a 405 Express Lanes violation is civil, it does not appear on your California driving record maintained by the Department of Motor Vehicles. It will not increase your insurance premiums or count as a moving violation. However, if you do not pay the violation and Metro reports it to a credit bureau, it can damage your credit score in the same way an unpaid medical bill or utility bill would.

The enforcement process is also different. Traffic citations are issued by law enforcement officers and can be contested in traffic court. 405 Express Lanes violations are issued by Metro and are contested through Metro's administrative hearing process, not the court system. The hearing officer is a Metro employee, not a judge.

Frequently Asked Questions

Can I get a violation if my FasTrak transponder was broken?

Yes, but you may be able to contest it. If your transponder malfunctioned, you should request a hearing and provide evidence that your account was active and funded at the time of the violation. Metro may dismiss or reduce the violation if you can show the transponder was defective. Contact Metro customer service to report a broken transponder and request documentation of the malfunction date.

What if I was a passenger, not the driver?

The violation is issued to the vehicle's registered owner, not the driver. If you were not driving, you will need to identify the actual driver and either pay the violation yourself or pursue reimbursement from the driver. Metro does not have a process to transfer the violation to a different person.

Do I have to pay the violation if I dispute it?

No. You can request a hearing without paying first. However, if you do not request a hearing within 21 days, the important date to contest passes and you will owe the full amount plus late fees. Request a hearing before the important date if you plan to dispute the violation.

Will this violation affect my car insurance?

No. Because it is a civil toll violation and not a traffic citation, it does not appear on your driving record and will not increase your insurance rates. However, if you do not pay and Metro reports the debt to a credit bureau, it could indirectly affect you by lowering your credit score.

Can Metro suspend my license for an unpaid violation?

No, Metro cannot suspend your driver's license. However, Metro can place a hold on your vehicle registration renewal through the DMV, which prevents you from renewing your registration until the violation is paid. You cannot legally drive the vehicle without a valid registration.
