IRP Cab Card

Who This Applies To

• Drivers who need to understand what the IRP cab card is, why it must be in the vehicle, and what information roadside inspectors use from it.
• Fleet managers who received cab cards after an IRP renewal or vehicle supplement and need to verify the information before dispatching.
• Carriers who added vehicles to the IRP fleet mid-year and need to confirm the new cab card is in the vehicle before the first interstate trip.
• Owner-operators leased to a motor carrier who need to understand whether the cab card is under the carrier's name or their own.
• Drivers who received a roadside inspection citation related to a missing or expired cab card and need to understand what the citation covers.
• Fleet managers evaluating whether digital cab cards stored on a phone or tablet are acceptable in the jurisdictions where their vehicles operate.

What To Verify

• That the cab card lists the correct vehicle identifiers: the VIN, the license plate number, the unit number if applicable, and the registered gross weight. If any of these does not match the actual vehicle, the cab card does not prove compliance for that vehicle.
• The registration year shown on the cab card. An expired cab card — one showing a prior registration year — does not prove current IRP compliance even if the carrier renewed on time. After renewal, the old cab card must be replaced in the vehicle.
• Whether all IRP member jurisdictions are listed on the cab card or implied by the registration. Most IRP registrations cover all member jurisdictions automatically — but if a specific jurisdiction is missing, operating there without coverage may trigger an audit or citation.
• Whether digital or electronic cab cards are accepted in the jurisdictions where the vehicle operates. Most U.S. states accept digital credentials, but acceptance varies — verify with the base jurisdiction before relying on a digital-only version in a multi-state operation.
• How the cab card relates to the apportioned plate. Both must be present together to prove IRP registration: the plate identifies the vehicle as apportioned; the cab card shows the registration year, vehicle, weight covered, and jurisdictions. Neither alone is complete.
• Whose cab card should be in a leased truck. Under a carrier lease, the vehicle typically operates under the carrier's IRP account with the carrier's cab card in the vehicle. The lease agreement should specify who holds IRP registration — and the driver should know which party's account covers the truck.

Step-by-Step Overview

1. When a new cab card is received from the base jurisdiction, compare every field against the vehicle records before dispatching: VIN, license plate, unit number, registered weight, and registration year. Discrepancies must be corrected with the base jurisdiction before the vehicle operates.
2. Place the new cab card in the vehicle's document holder, glove box, or cab document pouch immediately. If the base jurisdiction provides two copies, keep one in the vehicle and one in the back-office registration file.
3. Remove and destroy any expired cab card from the vehicle at the same time the new card is placed. A driver presenting an expired card during a roadside inspection while a current card is somewhere in the cab creates unnecessary enforcement risk.
4. For supplemental vehicles added mid-year, confirm the cab card has been issued and is in the vehicle before authorizing the first interstate trip. A vehicle on an IRP account without an issued cab card is not yet properly credentialed.
5. If a cab card is lost or damaged, contact the base jurisdiction immediately for a replacement. Many base jurisdictions can reissue within a few business days. Until the replacement arrives, carry documentation of the replacement request.
6. For leased vehicles, verify with the motor carrier that the cab card in the vehicle is current, shows the correct VIN, and is under the carrier's IRP account — before the owner-operator accepts the first dispatch under the lease.

Common Mistakes

• Operating with the prior year's cab card after the annual IRP renewal. Even if the carrier renewed on time, a vehicle that still has the old cab card in the cab has a compliance gap — the roadside inspector sees an expired document, not a valid registration.
• Dispatching a supplemental vehicle immediately after adding it to the IRP account without confirming the cab card has been issued. The IRP account may show the vehicle as added, but the cab card — which must be physically in the vehicle — may take additional days to arrive.
• Assuming the apportioned plate alone proves IRP compliance. The plate indicates the vehicle is registered under an apportioned system but does not show registration year, registered weight, or jurisdiction coverage. Inspectors check both the plate and the cab card.
• Not updating the cab card after a weight change. If the registered weight was changed during a supplement or renewal, the old cab card showing the prior weight is no longer accurate — operating above the weight shown on the cab card creates overweight exposure.
• Keeping multiple cab card versions in the vehicle — current plus an old one from a prior supplement. Inspectors who find multiple versions may flag the documents; some may interpret the presence of multiple cards as a sign that the correct version is unclear.
• Not verifying cab card acceptance rules for specific jurisdictions when considering electronic versions. A digital cab card displayed on a phone may be accepted in most states but rejected in others — verify before relying on electronic-only credentials.
