Actually, they're not explicitly illegal in any US state, even the Blue ones. In fact, while no permit is required, the California Highway Patrol notes the California DMV's Senior Guide for Safe Driving recommends their use for drivers who need assistance with steering, especially with power steering.
California-Specific Rules
No general ban: According to the Orange County Register and the California Highway Patrol, there is no Vehicle Code section in California that bans the use of steering wheel knobs on private vehicles.
Mechanism requirement: California Code of Regulations, Title 8, Section 1593, states that a steering knob cannot be attached unless the steering mechanism prevents the handwheel from spinning from road reactions.
Mounting requirement: The knob must also be mounted within the periphery of the steering wheel.
Recommended Use
Senior Driver Aid:
The California DMV's Senior Guide for Safe Driving suggests using a turning knob if you still have trouble steering.
Mobility Assistance:
Steering knobs can be a vital aid for individuals with limited hand or arm mobility, allowing them to operate their vehicle safely and comfortably.
Key Takeaway
Steering wheel knobs are legal to use in California, provided they meet the mounting and mechanism requirements outlined in the California Code of Regulations.
They are a legitimate assistive device for those who require them, rather than a universally prohibited accessory.
Here in Texas, the spinners may be regulated in commercial vehicles, but not in privately-owned vehicles. It is recommended to not use spinners that stick out past the rim diameter (like on a projecting arm), which could catch on a sleeve or something, but min is mounted almost perpendicularly atop the wheel rim, and doen't stick out but maybe a 1/2". I hardly ever wear loose sleeves, anyway.
I'll probably remove the spinner when/if I recover more mobility in my right arm, and/or my left wrist/thumb gets better.
