How to Remove a Restriction on a CDL in California
At SPCDL Truck Driving School, we specialize in helping students remove restrictions from their CDL, whether they’re new or existing drivers.
Steps to Remove a CDL Restriction
-
Obtain a New Permit:

- This permit allows you to train on vehicles that meet the unrestricted requirements and does not affect your current CDL.
-
Air Brake Training and Testing (if applicable):
- Watch SPCDL’s modernized air brake video to prepare for the air brake test and light check.
- Complete training and testing in a vehicle with air brakes. If also removing an air brake restriction, it requires a full test including pre-trip, skills, and driving test.
-
Manual Transmission Training:
- Train and test in a manual transmission vehicle to remove the automatic restriction.
-
Schedule and Attend Testing:
- SPCDL will schedule your test and provide hands-on training 1-2 days before the test date.

-
Complete Federal Waiting Period:
- Federal rules require a 14-day waiting period from the date of permit issuance before testing.
-
Pass Your Drive Test:
- Once you pass, your CDL will be updated to reflect the removal of restrictions.

What are CDL Restriction Codes?
CDL restriction codes are limitations placed on a commercial driver's license (CDL) that restrict the type of vehicles a driver can operate or the conditions under which they can drive.
These restrictions often result from training taken on specific vehicles or tests passed with certain limitations (e.g., automatic transmission).
Drivers can remove these restrictions by completing additional testing or training that fulfills federal and state requirements for the license class or endorsements.
Common CDL Restrictions and Their Meanings
B (This is a CDL Class, Not a Restriction)
- Meaning: Limits the driver to operating Class B or Class C vehicles, not Class A vehicles.
- Cause: The driver completed training and testing in a Class B vehicle.
- Removal: Requires testing in a Class A vehicle.
E Restriction (NO Manual Transmission Equipped CMV)
- Meaning: Driver is restricted to vehicles with automatic transmissions. Prohibits operation of manual transmission vehicles (automatic only).
- Cause: The behind the wheel tests were conducted using an automatic transmission vehicle.
- Removal: Requires passing a driving test in a manual transmission vehicle.
K Restriction on CDL (Intrastate Only)
- Meaning: Restricts driving to intrastate only (within the state).
- Cause: Intrastate was checked on the CDL application, under 21 years old, or other limitations preventing interstate operation.
- Removal: Requires submitting a new application with interstate checked, submission of a new DOT medical after turning 21 years old or other statutory requirements.
NOTE: SPCDL Truck Driving School cannot assist with K restriction CDL removal. You must obtain medical a medical certification and submit your documentation to DMV if you are under 21 years old.
Anyone under 21 has an intrastate license. On or after your 21st birthday, you can go get a new DOT medical physical, submit it to DMV to remove your intrastate CDL restriction.
If you are 21 and older, you just submit a new application to DMV to remove the intrastate restriction and obtain your interstate CDL.
L Restriction on CDL
Restricts the driver from using full air brakes
- Meaning: Limits the driver to operating vehicles without air brakes.
- Cause: The driver did not test on a vehicle equipped with air brakes.
- Removal: Requires passing the air brake written test and a full test in a vehicle with air brakes.
M Restriction on CDL
- Meaning: Restricts the driver to operating only Class B or C passenger vehicles or school buses.
- Cause: Testing in passenger vehicles not qualifying for Class A operation.
- Removal: Testing in a Class A passenger vehicle.
N Restriction on a CDL: No Class A or B Bus Passenger Vehicle
The N restriction on a Commercial Driver’s License (CDL) means that the driver is not authorized to operate Class A CDL or Class B CDL passenger-carrying vehicles, such as buses designed to transport passengers.
Key Details About the N Restriction
- Scope of Restriction:
Prohibits operating passenger buses or similar vehicles classified under Class A (combination vehicles) or Class B (single vehicles).
Applies specifically to vehicles designed to carry passengers, regardless of whether they are loaded or empty.
- Reason for the Restriction:
The driver did not complete the required testing or certification to safely operate passenger vehicles under Class A or B CDL categories.
The restriction may also apply if the driver passed their skills test in a non-passenger vehicle, such as a cargo truck, without demonstrating proficiency in passenger transport.
Impact of the N Restriction
- Limited Driving Privileges:
Drivers with the N restriction are limited to non-passenger CMVs in Class A or B categories, such as freight trucks or tank vehicles.
- Career Limitations:
This restriction prevents employment in roles that involve transporting passengers, such as bus drivers for transit systems, school buses, or charter services.
How to Remove the N Restriction
To remove the N restriction and gain authorization to operate passenger vehicles, the driver must:
- Pass the Passenger Endorsement Knowledge Test:
- Demonstrate an understanding of safety protocols, passenger management, and vehicle operation.
- Complete Skills Testing in a Passenger Vehicle:
- Successfully perform driving maneuvers, passenger loading/unloading, and vehicle inspections in a Class A or B passenger vehicle.
- Update CDL at the DMV:
- Submit proof of testing and certification to the state’s Department of Motor Vehicles (DMV) to remove the restriction.
O Restriction on CDL
- Meaning: Restricts the driver from operating a Class A vehicle with a fifth-wheel connection (tractor-trailer combination).
- Cause: Testing was conducted on vehicles that were not tractor-trailers, e.g. large travel trailer requiring a non-commercial driving license.
- Removal: Requires testing on a tractor-trailer vehicle.
Breaking Down the P Restriction and Its Variants on a CDL
When it comes to the "P" designation on a Commercial Driver’s License (CDL), it can either refer to a restriction or an endorsement depending on the context. Let’s clarify the differences:
-
"P" Restriction
Meaning:
This restriction prohibits the driver from operating a Commercial Motor Vehicle (CMV) designed to carry passengers, such as buses or vans.
It ensures the driver cannot transport passengers until the proper testing and certification are completed.
Cause:
The "P" restriction is added when a driver tests in a CMV designed for passenger transport but fails to demonstrate the skills required to operate such vehicles safely.
For example, the driver might have tested in a bus without passengers, failing to meet passenger-specific criteria.
Removal:
To remove the "P" restriction, the driver must:
Test in a CMV designed to carry passengers (e.g., a bus).
Successfully demonstrate their ability to operate a CMV safely while carrying passengers.
Example Use:
A driver with a "P" restriction might only be allowed to drive cargo vehicles but not buses until the restriction is removed.
-
"P1" Restriction
Meaning:
The "P1" restriction indicates the driver is limited to excepted interstate driving.
"Excepted interstate" refers to operating a CMV for purposes exempt from Federal Motor Carrier Safety Regulations (FMCSRs), such as certain government or agricultural activities.
Cause:
This restriction applies when the driver is medically certified or registered under an exception that limits their driving to specific interstate activities.
Removal:
Removal involves meeting medical qualification standards and obtaining a non-excepted medical certificate if the driver wishes to drive interstate for non-exempt purposes.
Example Use:
A driver with a "P1" restriction might be restricted to hauling goods for a government project across state lines but cannot engage in general passenger or commercial transport.
-
"P" Endorsement
Meaning:
The "P" endorsement allows a driver to operate a CMV designed to carry passengers.
This is a privilege added to the CDL, not a restriction.
Required for operating buses, large vans, or any vehicle designed to transport more than 15 passengers (including the driver).
Cause:
The driver has successfully completed both the written test and skills test in a passenger-carrying CMV.
Requirements for Obtaining:
Written Exam: Covers rules, regulations, and safety practices for passenger vehicles.
Skills Test: Requires demonstrating the ability to safely operate a passenger CMV with passengers onboard.
Example Use:
A school bus driver or charter bus operator needs the "P" endorsement to legally carry passengers.
Key Differences
| Category | P Restriction | P1 Restriction | P Endorsement |
|---|---|---|---|
| Definition | Prohibits carrying passengers in a CMV. | Restricts to excepted interstate driving. | Authorizes carrying passengers in a CMV. |
| Cause | Testing in a CMV without demonstrating passenger safety. | Medical or regulatory exemption limits. | Successful passenger-specific CDL tests. |
| Removal/Obtaining | Retest in a passenger CMV with passengers. | Meet medical standards and obtain full qualification. | Complete written and skills exams for passenger CMVs. |
| Example Use | CMV cargo drivers who can't operate buses. | Drivers limited to exempted activities. | Bus and large van drivers carrying passengers. |
V Restriction on a CDL: Medical Variance
The "V" restriction on a Commercial Driver’s License (CDL) signifies that the driver has been granted a medical variance by the Federal Motor Carrier Safety Administration (FMCSA). This designation is related to the driver’s medical qualifications and ensures compliance with federal regulations while addressing specific medical conditions.
What Does the V Restriction Mean?
- The "V" restriction indicates that the driver has received a medical exemption or waiver from the FMCSA, allowing them to operate a commercial vehicle despite not fully meeting the standard medical requirements.
- It ensures that the driver’s medical condition is managed under strict guidelines to maintain safety on the road.
Examples of Medical Variances:
The "V" restriction applies to drivers with certain medical conditions, such as:
- Vision Exemption:
- For drivers who do not meet the minimum vision standards but can safely operate a CMV with specific accommodations.
- Diabetes Exemption:
- For drivers managing diabetes with insulin who do not meet the general medical standards but qualify for an exemption through the FMCSA.
- Hearing Exemption:
- For drivers who do not meet the hearing standards but have demonstrated their ability to safely operate a CMV.
How is a Medical Variance Obtained?
To receive a medical variance, the driver must:
- Apply to the FMCSA:
- Submit a formal application detailing the medical condition and supporting documents from a licensed healthcare provider.
- Undergo an Evaluation:
- Pass an in-depth review process to determine if the condition can be managed safely while operating a CMV.
- Comply with Monitoring Requirements:
- Regularly report health updates and adhere to specific medical management protocols outlined by the FMCSA.
- Receive a Medical Variance Letter:
- Drivers granted a variance will receive an official letter from the FMCSA, which must be carried alongside their CDL.
Requirements for V Restriction Drivers
- Medical Certification:
- The driver must carry a valid medical certificate in addition to the FMCSA medical variance documentation.
- Regular Check-Ups:
- Continuous monitoring and reporting of the medical condition to ensure the driver remains fit to operate a CMV.
- Adherence to Exemption Terms:
- The driver must strictly follow all guidelines and limitations associated with the variance.
Impact of the V Restriction
- Allows Employment Opportunities:
- Enables individuals with managed medical conditions to maintain or pursue a career in commercial driving.
- Ensures Safety Compliance:
- The restriction ensures that drivers with variances meet safety standards while addressing their medical needs.
- Notifies Employers:
- Employers are made aware of the variance and must ensure compliance with FMCSA regulations.
How to Remove the V Restriction
The "V" restriction is tied to the medical variance. To remove it:
- Demonstrate Full Medical Compliance:
- The driver must meet all standard FMCSA medical requirements without needing a variance.
- Obtain Medical Examiner’s Certification:
- Submit a medical certificate confirming full compliance with federal standards.
- Update CDL:
- Visit the state’s Department of Motor Vehicles (DMV) to update the CDL and remove the restriction.
X Restriction on a CDL: No Cargo in CMV Tank Vehicle
The X restriction on a Commercial Driver’s License (CDL) signifies that the driver is not authorized to transport any cargo in a tank vehicle classified as a Commercial Motor Vehicle (CMV). This restriction limits the driver to operating empty tank vehicles without any load.
What Does the X Restriction Mean?
- The "X" restriction is applied to CDL holders who:
- Have successfully obtained a tank vehicle (N) and hazardous materials (H) endorsement but are restricted from transporting actual cargo (e.g., liquids or gases) in a tank vehicle.
- This typically occurs when the driver completes the required knowledge test but does not meet specific federal or state requirements to transport cargo in tank vehicles.
When Is the X Restriction Applied?
The X restriction is added to a CDL in scenarios such as:
- Testing in an Empty Tank Vehicle:
- The driver tested and passed in a tank vehicle without cargo but did not demonstrate proficiency in handling a fully loaded tank vehicle.
- Lack of Hazardous Materials Certification:
- The driver may not meet all the requirements for transporting hazardous materials, even though they have the tank endorsement.
- Partial Certification:
- The driver has completed knowledge-based testing but lacks additional qualifications, such as physical or operational requirements, to transport cargo.
Implications of the X Restriction
- Limits Cargo Transport:
- Drivers with the X restriction can operate tank vehicles but cannot legally transport cargo within those tanks.
- Affects Employment Opportunities:
- Certain jobs in the trucking industry that involve transporting liquids, gases, or other materials in tank vehicles will not be available to drivers with this restriction.
How to Remove the X Restriction
To remove the X restriction and gain full certification for transporting cargo in tank vehicles, drivers must meet the following requirements:
- Pass the Skills Test in a Loaded Tank Vehicle:
- Drivers must test in a fully loaded tank vehicle that meets federal standards.
- This demonstrates their ability to handle the unique challenges of operating a tank vehicle with cargo.
- Complete Hazardous Materials Certification (if required):
- For tank vehicles carrying hazardous materials, drivers must pass the hazmat written exam and complete the TSA background check.
- Obtain Federal and State Certification:
- Ensure compliance with Federal Motor Carrier Safety Administration (FMCSA) regulations and state-specific requirements for tank vehicle operation.
- Update CDL:
- Submit the updated test results and certifications to the state Department of Motor Vehicles (DMV) to remove the restriction.
Z Restriction on a CDL: No Full Air Brake Equipped CMV
The Z restriction on a Commercial Driver’s License (CDL) specifies that the driver is prohibited from operating a Commercial Motor Vehicle (CMV) that is fully equipped with air brakes. This restriction limits the types of vehicles the driver can legally operate, often impacting job opportunities that require handling vehicles with air brake systems.
What Does the Z Restriction Mean?
- The Z restriction prevents the CDL holder from operating CMVs that are fully equipped with air brakes.
- This typically includes large trucks, buses, and other commercial vehicles that rely on air brake systems for safe operation.
When Is the Z Restriction Applied?
The Z restriction is added to a CDL when:
- Testing in a Vehicle Without Full Air Brakes:
- The driver completes their CDL skills test in a vehicle equipped with hydraulic brakes or other braking systems rather than full air brakes.
- Lack of Air Brake Knowledge Test Completion:
- The driver did not pass the air brake knowledge test required for operating vehicles with this system.
- Partial Air Brake System Training:
- The driver trained or tested in a CMV with only a partial air brake system, such as air-over-hydraulic brakes, instead of full air brakes.
Implications of the Z Restriction
- Limits Vehicle Operation:
- Drivers cannot legally operate vehicles with full air brake systems, which are common in commercial transportation.
- Reduces Employment Opportunities:
- Many trucking and commercial driving positions require proficiency in handling vehicles with air brakes.
How to Remove the Z Restriction
To remove the Z restriction and gain full certification for operating air brake-equipped CMVs, drivers must:
- Pass the Air Brake Knowledge Test:
- Complete a written exam that tests understanding of air brake systems, their components, and safe operation.
- Test in a Vehicle Equipped with Full Air Brakes:
- The driver must complete their CDL skills test in a vehicle with a fully operational air brake system.
- Demonstrate the ability to perform tasks such as:
- Conducting a pre-trip inspection of the air brake system.
- Safely engaging and disengaging air brakes.
- Performing air brake leakage tests.
- Update CDL:
- Submit passing results to the state’s Department of Motor Vehicles (DMV) to remove the Z restriction and update the license.
Why Does This Z Restriction Matter?
The Z restriction ensures that drivers are not operating vehicles with air brake systems unless they have been adequately trained and tested to handle them safely. Air brakes are significantly different from hydraulic systems and require specific knowledge and skills, such as:
- Brake Lag Understanding: Air brakes have a slight delay between pressing the pedal and brake engagement.
- Air Pressure Monitoring: Drivers must know how to monitor and maintain adequate air pressure for braking.
- System Components: Familiarity with components such as compressors, reservoirs, and valves is critical for safety.
CDL Restrictions in Other States
While this page focuses on California, similar restriction codes and requirements apply in most other states. For example:
- Texas: Restriction codes mirror federal standards, with manual transmission and air brake restrictions common.
- Florida: Intrastate restrictions (K) and endorsements like Hazmat have additional state-specific requirements.
- New York: Passenger endorsements (P) and tractor-trailer restrictions (O) follow state and federal rules.
