A Caterpillar plate is a temporary registration that lets you drive a vehicle before it's fully registered

A Caterpillar license plate (also called a "temp tag," "temporary plate," or "transit plate") is a paper or cardstock registration that dealers and private sellers issue when you buy a vehicle but haven't yet received your permanent metal plate from the state. It's printed with an expiration date—usually 30 to 60 days out, depending on your state—and lets you legally drive the car while your permanent registration is being processed.

The name comes from the plate's appearance: it's typically long and narrow, printed on yellow or white paper with black text, and resembles a caterpillar in shape. You tape or clip it to your rear window or bumper so police can see it from behind. The plate includes your vehicle identification number (VIN), the dealer or seller's information, and an expiration date.

You need a Caterpillar plate because state motor vehicle departments take time to process new registrations—sometimes weeks. Without it, you'd be driving an unregistered vehicle, which is illegal and can result in fines or your car being impounded. The temporary plate bridges that gap.

Key Takeaways

  • A Caterpillar plate is a temporary paper registration that allows you to drive a newly purchased vehicle while waiting for your permanent metal plate from the state.
  • Dealers typically issue Caterpillar plates at the point of sale; private sellers may issue them if they have the authority, but this varies by state.
  • Caterpillar plates expire within 30 to 60 days and are not transferable between vehicles or owners.
  • Driving past the expiration date on a Caterpillar plate is illegal and can result in fines, traffic stops, or vehicle impoundment.
  • Your permanent registration should arrive by mail before the Caterpillar plate expires; if it doesn't, contact your state's motor vehicle department when ready.

Who issues a Caterpillar plate and when you receive it

A licensed dealer issues a Caterpillar plate at the time of sale. When you buy a car from a dealership, the dealer's office prints and attaches the temporary plate before you leave the lot. The dealer has the authority to do this because they are registered with the state to handle new vehicle sales and temporary registrations.

If you buy a vehicle from a private seller, the situation depends on your state. Some states allow private sellers to issue temporary plates if they have the proper forms and authority; others do not. In states where private sellers cannot issue them, you may need to go directly to your local motor vehicle office to get a temporary plate before you can legally drive the car home. Ask the seller or your state's motor vehicle department website which rule applies in your area.

You receive the Caterpillar plate at the moment the sale is complete. The dealer or authorized seller will print it, show you the expiration date, and attach it to your vehicle. You should also receive a receipt or document showing the plate number and expiration date for your records.

How long a Caterpillar plate lasts and what happens when it expires

A Caterpillar plate is valid for a set period—typically 30, 45, or 60 days depending on your state. The exact duration varies: some states print 30-day plates as standard, while others allow dealers to issue 60-day plates. Check the expiration date printed on your plate to know your important date.

During this time, your permanent registration is being processed by the state motor vehicle department. The department receives the paperwork from the dealer, verifies the vehicle information, checks that you've paid sales tax and registration fees, and prints your permanent metal plate. This process usually takes two to four weeks, but can take longer if paperwork is incomplete or if the department is backlogged.

Your permanent plate will arrive by mail at the address you provided during registration. Once it arrives, you remove the Caterpillar plate and install the permanent plate on your vehicle. Driving with an expired Caterpillar plate is illegal—you are operating an unregistered vehicle, which can result in a traffic citation, fine, or impoundment. Do not assume you can drive past the expiration date while waiting for your permanent plate.

What to do if your permanent plate hasn't arrived before the Caterpillar plate expires

If your expiration date is approaching and your permanent registration has not arrived, contact your state's motor vehicle department when ready. Do not wait until the plate expires. Call the department's customer service line or visit their website to check the status of your registration. You will need your VIN, the temporary plate number, or your driver's license number to look it up.

If the registration is still being processed, the department can sometimes issue an extension—a second temporary plate that gives you additional time. Not all states offer extensions, and some require you to visit an office in person to receive one. Ask what your state's policy is and what documents you need to bring.

If there is a problem with your paperwork—for example, a missing signature, incorrect VIN, or unpaid fee—the department will tell you what needs to be corrected. Fix it as quickly as possible, because the clock is still running on your current plate. In rare cases, if the delay is the department's fault and you cannot get an extension, document your attempts to contact them; this record may protect you if you are stopped by police before the permanent plate arrives.

Caterpillar plates cannot be transferred or reused

A Caterpillar plate is issued to a specific vehicle and a specific owner for a specific transaction. It is not transferable. If you sell the vehicle before the plate expires, the new owner cannot use your temporary plate. The new owner must obtain their own temporary plate from the dealer or motor vehicle department.

Similarly, if you buy multiple vehicles, each one receives its own Caterpillar plate with its own expiration date. You cannot move a plate from one car to another, and you cannot use an expired plate on a different vehicle.

Once your permanent plate arrives and you install it, the Caterpillar plate has no further use. You can discard it. Do not attempt to reuse it on another vehicle or keep it as a spare—it is invalid and will not protect you legally if you are stopped.

Common mistakes that get drivers cited or stopped

The most common mistake is driving past the expiration date. Many drivers assume they can continue driving until their permanent plate arrives, or they lose track of the date. Police can see the expired date from behind your vehicle and will stop you. You will be cited for operating an unregistered vehicle, which typically results in a fine ranging from $50 to several hundred dollars depending on your state.

Another mistake is failing to display the plate correctly. The plate must be visible from behind the vehicle. If you tape it to the inside of the rear window but it's obscured by tint, a headrest, or cargo, an officer may not be able to read it and may stop you. Attach it securely to the rear bumper or lower rear window where it's clearly visible.

A third mistake is not checking the plate for accuracy before you leave the lot. Verify that the VIN, expiration date, and dealer information are correct. If there is an error, ask the dealer to issue a corrected plate when ready. A wrong VIN on your temporary plate can cause serious problems when you try to register the vehicle permanently.

Frequently Asked Questions

Can I drive out of state with a Caterpillar plate?

Yes, a Caterpillar plate is valid for driving anywhere in the United States as long as it has not expired. However, if you are moving to another state, you will need to register the vehicle in that state before the temporary plate expires. Contact the new state's motor vehicle department to learn their registration process and timeline.

What if I lose or damage my Caterpillar plate?

Contact the dealer or the office that issued it when ready and ask for a replacement. Bring your receipt or documentation showing the original plate number. If the dealer is closed or unreachable, go to your local motor vehicle office; they can issue an emergency temporary plate or advise you on next steps. Do not drive without a visible temporary plate.

Do I need to carry the Caterpillar plate paperwork with me while driving?

Yes. Keep the receipt or documentation that shows your temporary plate number and expiration date in your vehicle. If you are stopped by police, this document proves that you have a valid temporary registration. You should also carry your bill of sale or purchase agreement and proof of insurance.

Can a dealer issue a Caterpillar plate for a used car?

Only if the dealer is a licensed used-car dealer with the authority to issue temporary registrations. Private used-car sales typically do not include a dealer-issued plate. In those cases, you and the seller must go to the motor vehicle office together, or the seller may give you a temporary plate form to take there yourself. Rules vary by state.

What happens if I buy a car but don't register it right away?

The Caterpillar plate will expire whether you register the vehicle or not. Once it expires, you cannot legally drive the car. You must complete the registration process and receive your permanent plate before the temporary plate expires. If you are not ready to register the vehicle, do not take the temporary plate.
