Whether You Need an IDP in California
You do not need an International Driving Permit (IDP) to drive in California if you hold a valid driver's license from another country. California law recognizes foreign licenses as long as they are current, written in English or accompanied by a certified English translation, and issued by your home country's licensing authority.
An IDP is useful only in specific situations: if your foreign license is not in English and you cannot obtain a certified translation, if you are renting a car and the rental company requires one, or if you plan to drive in multiple countries and want a document that works across borders. For California driving alone, your original foreign license is sufficient.
The key requirement is that your license must be valid in your home country. An expired license, a learner's permit, or a license suspended or revoked in your country of origin will not work in California, even with an IDP.
Key Takeaways
- A valid foreign driver's license is all you need to drive legally in California; an IDP is optional, not required.
- Your foreign license must be current and either in English or paired with a certified English translation.
- An IDP becomes necessary only if your license is not in English and you cannot get a certified translation, or if a car rental company demands one.
- An IDP does not replace your foreign license—you must carry both documents together to be legal.
- If your license is expired, suspended, or revoked in your home country, neither a foreign license nor an IDP will allow you to drive in California.
When Your Foreign License Alone Is Enough
If your driver's license is issued in English by your home country's licensing authority and is currently valid, you can drive in California with that license alone. You do not need to obtain an IDP. Police officers and rental car agents will accept your foreign license as proof that you are permitted to operate a vehicle.
Carry your original license at all times while driving. Do not carry only a photocopy or a photo on your phone. California law requires you to present your actual license if stopped by law enforcement.
When You Need a Certified English Translation
If your foreign license is written in a language other than English, California requires that you carry a certified English translation along with your original license. A certified translation is one prepared by a professional translator who has verified its accuracy and signed it under penalty of perjury.
You can obtain a certified translation through a professional translation service, many of which operate online. The cost varies but typically ranges from $20 to $50 per document. Some notary publics also offer certified translation services. Once you have the translation, carry both your original license and the certified translation together whenever you drive.
A certified translation serves the same legal purpose as an IDP in this situation—it allows you to drive with your foreign license. You do not need both a translation and an IDP; one or the other is sufficient.
When an IDP Becomes Necessary
An IDP is genuinely necessary in only a few scenarios. First, if your license is not in English and you cannot obtain or do not have a certified translation, an IDP can substitute. Second, some car rental companies in California require an IDP even when your foreign license is valid, so check with your rental company before you arrive. Third, if you plan to drive in multiple countries during your trip, an IDP works across borders and may be easier than obtaining translations in each country.
If you decide to get an IDP, you must obtain it from your home country before you travel to California. The United States does not issue IDPs. Your country's automobile association or licensing authority can tell you how to request one. Processing times vary by country but often take two to four weeks.
How to Get a Certified English Translation
A certified translation is faster and often cheaper than obtaining an IDP. To get one, locate a professional translator or translation service that offers certified translations. Many translators work online and can return your translated license within a few days.
When you contact a translator, provide your original license and ask for a certified English translation. The translator will translate the document and sign a certification statement confirming the translation is accurate. You will receive both your original license back and the certified translation. Keep them together in your wallet or vehicle.
Certified translations are recognized by California law enforcement and car rental companies. You do not need to register the translation or file it anywhere—it is valid as soon as the translator signs it.
What Happens If Your License Is Expired or Invalid
If your foreign license has expired, you cannot drive in California with it, even with an IDP or certified translation. An IDP does not extend the validity of an expired license. You would need to obtain a California driver's license instead.
Similarly, if your license was suspended or revoked in your home country, you cannot drive in California. The suspension or revocation follows you regardless of which document you carry. If you are in this situation, you will need to resolve the suspension or revocation in your home country first, or obtain a California license through the standard process for new drivers.
Driving with a Foreign License as a California Resident
If you have moved to California and established residency, you are required to obtain a California driver's license within a certain timeframe. California law does not specify an exact important date, but driving with only a foreign license after you become a resident can result in a citation for driving without a valid California license.
Residency is established when you register a vehicle in California, enroll in school, or obtain employment. If any of these explore to you, visit your local Department of Motor Vehicles office to explore for a California license. You will need to pass a written test and a driving test unless you are exempt based on your age or prior licensing history.
Frequently Asked Questions
Can I drive in California with just my foreign license and no translation or IDP?
Yes, if your license is in English and currently valid. If your license is in another language, you must carry a certified English translation or an IDP. Carry your original license in either case.
Do I need an IDP if I have a certified translation of my license?
No. A certified translation and an IDP serve the same purpose. You need only one or the other, not both. If you have a certified translation, an IDP is not necessary.
What if a rental car company asks for an IDP and I don't have one?
Contact the rental company before your trip and ask what documents they accept. Many will accept a certified English translation of your foreign license instead. If the company requires an IDP specifically, you will need to obtain one from your home country before you travel.
How long is an IDP valid?
An IDP is typically valid for one year from the date of issue. If you plan to stay in California longer than a year, you will need to renew it or obtain a California driver's license.
If I get an IDP, do I still need to carry my original foreign license?
Yes. An IDP is a translation and verification document, not a replacement for your license. You must carry both your original foreign license and the IDP together. Carrying only the IDP is not legal.
