Yes, steering wheel knobs are legal in California, but they must be installed properly and not interfere with the safe operation of the vehicle. While generally permitted, they are especially useful for drivers with disabilities, who may need them as an adaptive device. It’s important to ensure compliance with safety regulations and notify your insurance provider if you install one.
Steering wheel knobs, also known as spinner knobs or brodie knobs, are devices that attach to the steering wheel of a vehicle, allowing for one-handed steering. These devices can be particularly useful for individuals with disabilities, those who need to make tight turns frequently, or drivers of large vehicles like trucks and tractors.
However, the legality of steering wheel knobs can vary depending on local regulations. This article explores the legality of steering wheel knobs in California, providing an in-depth analysis of the laws, potential benefits, and considerations for drivers.

Federal Regulations and ADA Compliance
In the United States, federal law, particularly the Americans with Disabilities Act (ADA), plays a significant role in regulating adaptive devices like steering wheel knobs. Under the ADA, individuals with disabilities have the right to modify their vehicles with adaptive equipment to ensure they can drive safely and independently. Steering wheel knobs fall under this category of adaptive devices, making them legal for use by individuals with disabilities across the country, including in California.
However, while federal law provides broad protections and guidelines, the specific regulations regarding the use of steering wheel knobs are typically governed by state law.
California Vehicle Code and Steering Wheel Knobs
In California, the use of steering wheel knobs is generally legal, but certain conditions apply to ensure that their use does not compromise road safety. The California Vehicle Code does not explicitly prohibit the use of steering wheel knobs. However, drivers must ensure that these devices do not interfere with the safe operation of the vehicle.
One key aspect of the law is that any modification to a vehicle, including the installation of a steering wheel knob, must not impair the driver’s ability to control the vehicle effectively. This means that the knob must be securely attached and should not impede the steering wheel’s normal function.
Relevant Sections of the California Vehicle Code
- California Vehicle Code Section 24002: This section states that it is illegal to operate a vehicle that is in an unsafe condition or is not equipped in the manner provided by the Vehicle Code, thereby endangering the driver or others. If a steering wheel knob is installed improperly or causes issues with steering control, it could be considered a violation of this code.
- California Vehicle Code Section 24008: This section addresses modifications to vehicles, noting that such modifications must comply with safety standards. A steering wheel knob that affects the vehicle’s safety could potentially violate this code.
- California Vehicle Code Section 27600: Although primarily addressing windshield wiper usage, this section also touches upon vehicle modifications, implying that any such changes should not obstruct or limit the driver’s view or control over the vehicle.
Use by Drivers with Disabilities
For drivers with disabilities, steering wheel knobs can be a crucial adaptation that enables them to drive independently. In California, individuals with disabilities who use steering wheel knobs as an adaptive device are protected under the ADA and state laws. These drivers may need to obtain a special license endorsement, which involves a medical evaluation and possibly a driving test using the modified vehicle.
The California Department of Motor Vehicles (DMV) may require drivers to undergo a medical review if they need adaptive devices like a steering wheel knob. This review is intended to ensure that the driver can operate the vehicle safely with the modification. If approved, the DMV may issue a restricted license that specifies the use of such devices.
Considerations for Commercial Drivers
For commercial drivers in California, the use of steering wheel knobs is generally permitted, but it comes with specific considerations. The California Commercial Driver Handbook does not explicitly prohibit steering wheel knobs but emphasizes the importance of vehicle control and safety. Commercial drivers should ensure that the knob is installed correctly and does not interfere with their ability to operate the vehicle, especially in emergency situations.
Furthermore, some commercial trucking companies may have their own policies regarding steering wheel knobs, so drivers should check with their employers or fleet managers before installing one.
Insurance Implications
While steering wheel knobs are legal in California, drivers should be aware of potential insurance implications. Installing a steering wheel knob is considered a modification to the vehicle, and it’s important to inform your insurance provider of any such changes. Failure to do so could affect coverage in the event of an accident.
Insurance companies may require documentation that the steering wheel knob was installed professionally and that it does not compromise the vehicle’s safety. For drivers with disabilities, providing medical documentation and proof of the DMV’s approval of the modification can help ensure that the insurance policy accurately reflects the vehicle’s adaptations.
Safety Considerations and Best Practices
While steering wheel knobs can offer significant benefits, there are also important safety considerations to keep in mind:
- Proper Installation: Ensure that the steering wheel knob is securely attached and does not come loose during driving. A poorly installed knob can lead to loss of control, which is dangerous.
- Quality and Compatibility: Use a high-quality steering wheel knob that is compatible with your vehicle’s steering system. Cheap or incompatible knobs may not function properly and could pose a safety risk.
- Impact on Airbags: In vehicles equipped with airbags, it is crucial to consider how the steering wheel knob might affect airbag deployment. The knob should not obstruct or interfere with the airbag’s operation.
- Driver Training: Using a steering wheel knob requires some adjustment in driving technique. It is recommended that drivers practice using the knob in a controlled environment before relying on it in regular driving conditions.
Legal Precautions and Documentation
To ensure compliance with California laws and regulations, drivers using steering wheel knobs should take the following precautions:
- Check Local Laws: While steering wheel knobs are generally legal in California, drivers should check for any local ordinances or restrictions that might apply, particularly in commercial driving or specific municipalities.
- Medical Documentation: For drivers with disabilities, keeping medical documentation or a letter from a healthcare provider that explains the need for the steering wheel knob can be beneficial, especially in the event of a traffic stop or accident.
- Insurance Notification: Always inform your insurance provider about the installation of a steering wheel knob. This helps ensure that your policy reflects the modifications to your vehicle and that you have appropriate coverage.
