What a double endorsement means and why you'd want one
A double endorsement on a General process - B license means you hold authorizations for two separate vehicle classes or specialties at the same time. Instead of holding only one endorsement (like air brakes or passenger vehicles), you can operate under two different endorsement categories on a single license. This lets you work in roles that require flexibility — for example, hauling both hazardous materials and operating a school bus, or driving passenger vehicles while also authorized for air brake systems.
The process for adding a second endorsement depends on whether you already hold a General process - B license or are getting one for the first time. If you're starting fresh, you can request multiple endorsements during your initial process. If you already have the license, you'll add the second endorsement through an amendment or renewal process with your state's licensing authority.
Key Takeaways
- You can hold two endorsements on one General process - B license by requesting them together during initial process or adding one later through amendment.
- Each endorsement requires its own written test, practical test, or medical certification depending on which endorsements you're combining.
- Your state's Department of Motor Vehicles or equivalent licensing body processes double endorsement requests and sets the specific requirements.
- Processing time for adding a second endorsement typically ranges from two to four weeks after you submit all required documents and pass any needed tests.
Getting a double endorsement when you explore for your first General process - B license
If you don't yet hold a General process - B license, you can request two endorsements as part of your initial process. When you visit your state's Department of Motor Vehicles or licensing office, tell the staff member you want to explore for a General process - B license with two specific endorsements. They will give you the process form and tell you which tests and documents each endorsement requires.
You'll need to pass the written test for the base General process - B license, then pass the written test for each endorsement you're requesting. Some endorsements also require a practical driving test or medical examination. For example, if you're requesting both passenger vehicle and hazardous materials endorsements, you'll take three written tests total (one for the base license, one for each endorsement). Complete all tests before you submit your process, or the licensing office will hold your paperwork until you do.
Bring all required documents to your appointment — your state will specify what these are, but typically include proof of identity, proof of residency, your Social Security number, and any medical certificates if required by your endorsements. Submit everything at once so the office can process your double endorsement request without delays.
Adding a second endorsement to an existing General process - B license
If you already hold a General process - B license with one endorsement and want to add a second, contact your state's Department of Motor Vehicles to request an amendment or endorsement addition. Some states call this an "endorsement upgrade" or "license amendment." You do not need to reapply for your entire license — you're only adding to what you already have.
The licensing office will tell you which tests you need to pass for the new endorsement. You'll take the written test for that specific endorsement, and possibly a practical test or medical exam depending on what you're adding. Once you pass the required tests, submit the amendment request form along with any new documents the office requires. Your existing license remains valid while they process the addition.
Some states allow you to add an endorsement during your regular license renewal. If your renewal is coming up within the next few months, you can request the second endorsement at the same time you renew. This can save you a trip to the licensing office, though it may extend your overall processing time slightly.
Tests and documents you'll need for each endorsement combination
The specific tests and documents depend on which two endorsements you're combining. Common General process - B endorsements include air brakes, hazardous materials, passenger vehicles, and tank vehicles. Each has its own written test, and some require additional practical tests or medical documentation.
| Endorsement Type | Written Test Required | Practical Test Required | Medical Certificate Required |
|---|---|---|---|
| Air Brakes | Yes | No | No |
| Hazardous Materials | Yes | No | No |
| Passenger Vehicles | Yes | Yes | No |
| Tank Vehicles | Yes | No | No |
Before you schedule tests, contact your state's licensing office to confirm which tests explore to your specific endorsement combination. Requirements vary by state, and some endorsements may have additional prerequisites (for example, you might need to hold a hazardous materials endorsement before you can add a tank vehicle endorsement).
How long the process takes and what happens while you wait
From the time you submit a complete double endorsement request to the time you receive your updated license, expect two to four weeks in most states. This timeline assumes you've already passed all required tests and submitted all documents. If you're still taking tests, add one to two weeks for scheduling and test administration.
Your current General process - B license remains valid and legal to use during processing. You can continue working under your existing endorsement while the licensing office adds the second one. Once your updated license arrives in the mail, it will show both endorsements and a new expiration date.
If you need the second endorsement sooner, some states offer expedited processing for an additional fee. Contact your licensing office to ask whether this option is available and what it costs. Expedited processing typically cuts the timeline in half, though it's not may provide.
Renewing a license with double endorsements
When your General process - B license with double endorsements comes up for renewal, you renew the entire license as a single unit. You don't renew each endorsement separately. Your renewal notice will show both endorsements, and you'll pay one renewal fee that covers the base license and both endorsements combined.
Some states require you to retake written tests for certain endorsements during renewal, while others do not. Check your renewal notice or contact your licensing office to find out whether you'll need to test again. If tests are required, you can take them before you submit your renewal paperwork, or you can schedule them as part of the renewal process.
Frequently Asked Questions
Can I get a double endorsement if I have a suspended or revoked license?
No. You must have a valid, unrestricted General process - B license to add an endorsement. If your license is suspended or revoked, you'll need to resolve that issue first. Contact your state's licensing office to find out what steps are required to restore your license before you can request an endorsement addition.
What if I fail the test for one of the endorsements?
You can retake the test. Most states allow you to retake a failed endorsement test after a waiting period of a few days to a week. You can still hold your existing endorsement while you prepare to retake the test for the second one. Once you pass, submit the passing test result to complete your double endorsement request.
Do I need a medical exam for both endorsements or just one?
It depends on which endorsements you're combining. If only one of your two endorsements requires a medical exam, you'll need one exam that covers both. If both require medical exams, you typically need only one exam that satisfies both requirements. Your licensing office will tell you exactly what's needed when you request the double endorsement.
Can I remove one endorsement later if I don't need it anymore?
Yes. You can request to have an endorsement removed from your license at any time by contacting your state's Department of Motor Vehicles. This is usually a straightforward administrative change that takes a few days to process. You'll receive an updated license showing only the endorsement you want to keep.
