What "converting" your driver's license means
Converting your driver's license means changing it from one class to another — for example, from a standard Class D (passenger vehicle) license to a Class C (commercial vehicle) license, or from a learner's permit to a full license. You do not get a new license number; the DMV updates your existing record and issues you a new card with the new class printed on it.
The process and requirements depend on which class you are converting to and which state you live in. Some conversions require a written test, a road test, or both. Others require only paperwork and a fee. A few require medical certification or a background check.
You cannot convert online in any state. You must visit your DMV office or an authorized agent in person, bring specific documents, and often pay a fee that ranges from $20 to $150 depending on the license class and your state.
Key Takeaways
- Converting to a commercial driver's license (CDL) requires a written knowledge test, a skills test, and a medical certificate, and takes at least several weeks in most states.
- Converting from a learner's permit to a full license requires passing a road test and sometimes a written test, depending on your state and how long you have held the permit.
- Converting to a motorcycle endorsement requires a written test and usually a riding skills test, though some states waive the riding test if you complete an approved motorcycle safety course.
- You must bring your current license, proof of residency, and proof of citizenship or legal presence to the DMV, plus any additional documents your state requires for the specific class you are converting to.
- Fees for conversion vary by state and license class but typically range from $20 to $150, and you will receive your new license card by mail within one to three weeks.
Converting from a learner's permit to a full driver's license
If you hold a learner's permit (also called a learner's license or provisional license), you can convert it to a full Class D license once you meet your state's requirements. Most states require you to hold the permit for a minimum period — often six months to one year — and then pass a road test. Some states also require a written test or a vision test at the time of conversion.
To convert, visit your DMV office with your current permit, proof of residency, and proof of citizenship or legal presence. Bring your Social Security number or card. You will pay a fee (typically $15 to $50) and take the road test on the same day or schedule it for a later appointment. If you pass, the DMV will issue your new full license card within one to three weeks.
If you fail the road test, you can usually retake it after a waiting period — often 7 to 14 days. You may have to pay the test fee again. Check your state DMV website for the exact waiting period and retake rules.
Converting to a commercial driver's license (CDL)
A commercial driver's license (CDL) is required to drive a truck, bus, or other vehicle over a certain weight or carrying hazardous materials. Converting from a standard license to a CDL is more involved than other conversions and typically takes four to eight weeks.
First, you must obtain a commercial learner's permit (CLP) by passing a written knowledge test at the DMV. The test covers federal and state commercial driving rules, vehicle inspection, and safe driving practices. You study using the CDL manual, which your state DMV provides free online or in print. After you pass, you receive the CLP and can practice driving a commercial vehicle with a licensed CDL holder in the passenger seat.
Next, you must pass a medical examination by a certified medical examiner and obtain a Medical Certificate. This certificate confirms you meet federal health standards for commercial driving. The exam costs $50 to $150 and covers vision, hearing, blood pressure, and other health factors. You submit the certificate to the DMV as part of your CDL conversion.
Finally, you take the CDL skills test, which has three parts: a pre-trip vehicle inspection, a basic control skills test (backing, turning, parking), and a road test. You must pass all three. The skills test is administered by the DMV or an approved third-party tester and costs $50 to $200. Once you pass, the DMV issues your CDL card.
Converting to a motorcycle endorsement
A motorcycle endorsement (also called a motorcycle license or "M" endorsement) allows you to legally ride a motorcycle. You can add it to your existing driver's license without converting your license class. The process is simpler than a CDL conversion but still requires testing.
Visit your DMV and request a motorcycle endorsement. You will take a written knowledge test covering motorcycle-specific rules, handling, and safety. If you pass, you move to the skills test, which is a riding test on a closed course. You must demonstrate control, balance, and safe riding. Some states waive the riding test if you complete an approved motorcycle safety course (such as the Motorcycle Safety Foundation course). Check your state DMV website to see if your state offers this waiver.
The written test costs $10 to $30. The riding test costs $20 to $50, or is free if you take an approved safety course (though the course itself costs $150 to $300). Once you pass, your license is reissued with the motorcycle endorsement within one to three weeks.
Converting to a taxi, limousine, or for-hire vehicle license
Some states issue a separate license class for drivers of taxis, limousines, ride-share vehicles, or other for-hire services. The requirements vary widely by state and sometimes by city. Most require a background check, a driving record review, and proof of insurance. Some require a written test on local traffic laws or passenger safety rules.
Contact your state DMV or your city's taxi and limousine commission to learn the specific requirements. You will likely need to provide a clean driving record (no major violations in the past three to five years), proof of a valid standard driver's license, and proof of commercial auto insurance. The fee ranges from $50 to $300, and processing takes two to four weeks.
Documents you need to bring to the DMV
For any license conversion, bring the following documents to your DMV office:
- Your current driver's license or learner's permit
- Proof of residency (utility bill, lease, or bank statement dated within the past 60 days)
- Proof of citizenship or legal presence (passport, birth certificate, green card, or visa)
- Social Security number or card
- A completed process form (your state DMV provides this; some allow you to fill it out online before you visit)
For a CDL conversion, also bring your Medical Certificate (obtained from a certified medical examiner). For a for-hire vehicle license, bring proof of insurance and any local permits or background check clearances your city requires.
Check your state DMV website before you visit, because some states have additional requirements — for example, proof of a Social Security number, a notarized affidavit, or a vision test result from an eye doctor.
Fees and timeline for license conversion
| License Type | Typical Fee | Processing Time | Tests Required |
|---|---|---|---|
| Learner's permit to full license | $15–$50 | 1–3 weeks | Road test (written test in some states) |
| Commercial driver's license (CDL) | $100–$350 | 4–8 weeks | Written test, medical exam, skills test |
| Motorcycle endorsement | $30–$80 | 1–3 weeks | Written test, riding test (waived with safety course) |
| For-hire vehicle license | $50–$300 | 2–4 weeks | Background check, written test (varies by city) |
Fees vary by state. The timeline assumes you pass all tests on the first attempt. If you fail a test, you will need to retake it after a waiting period, which extends the overall timeline by one to four weeks per retake.
Frequently Asked Questions
Can I convert my license online?
No. You must visit a DMV office or authorized agent in person for any license conversion. Some states allow you to fill out the process form online before you visit, which can speed up the process, but you cannot complete the entire conversion remotely.
What happens if I fail the road test or written test?
You can retake the test after a waiting period, which is usually 7 to 14 days for a road test and 1 to 7 days for a written test. You will pay the test fee again. Most states allow you to retake a test three to five times before you must wait a longer period or reapply. Check your state DMV website for the exact retake policy.
Do I keep my old license number when I convert?
Yes. Your license number stays the same. The DMV updates your record to reflect the new license class and issues you a new card with the same number but a new expiration date and the updated class printed on it.
Can I convert my license if I have an out-of-state license?
You must first convert your out-of-state license to an in-state license by visiting the DMV with proof of residency and citizenship. Once you have an in-state license, you can convert it to a different class using the process described above. Some states allow you to do both conversions in one visit.
How long is a converted license valid?
A converted license is valid for the same period as a new license in your state — typically four to eight years for a standard driver's license, and five to ten years for a CDL. Your new expiration date will be printed on your license card.
