Are Steering Wheel Knobs Illegal?
According to suicideknob.net, a website dedicated to steering wheel spinners, no state law prohibits their use, but they may be illegal under some local city laws and ordinances. Confirm their legal status with local police and the Department of Motor Vehicles (DMV) before installing one.
A steering wheel knob makes it easier to steer a vehicle with one hand, making them ideal accessories for drivers with disabilities that make driving with both hands difficult or impossible. In addition to some local ordinances restricting their use in private and commercial vehicles, Occupational Safety & Health Administration (OSHA) regulations limit the use of spinner knobs on industrial vehicles.
