Where do you put your hands on the steering wheel when driving? I noticed one person at the 10 to 2 position (oh dear), then everyone else seemed to have just their right hand on the wheel, but near the top! I thought most people (unless they're learning to drive) put their hand at the bottom.
You probably get away with 10 and 2. It is high noon that will get you
a punch in the face. Rings and watches only make that worse.
If things are getting dicey, you probably want both hands on the wheel
It is sort of like a door knob that is placed on the rim of the stering
wheel. You grip it with one hand and use it to turn the stering wheel.
The knob will face you and is made to rotate so you can get a good grip on
Makes it easy to back up the car and drive with one hand while drinking the
beer with the other.
I think the government made it illegal in the US because it might hirt you
in a crash.
Perhaps OSHA doesn't want "handicapped people" hauling hazardous
Actually, I don't see an outright ban on them, but I just skimmed over
Steering or spinner knobs shall not be attached to the steering wheel
unless the steering mechanism is of a type that prevents road reactions
from causing the steering handwheel to spin. The steering knob shall be
mounted within the periphery of the wheel.
Ah, so something to do with driving your construction vehicle on a rough track and your hand getting broken when the wheel suddenly moves. Much like don't put your thumbs on the inside of the 4x4 steering wheel when going offroad.
I failed my audition as Romeo through a misunderstanding over a stage direction. In my script it clearly said, "Enter Juliette from the rear."
In New York State, however, a doctor's prescription for a spinner now
must be submitted to the NYSDMV, which in turn, shows that the knob is
"required" on all vehicles the user drives and such requirement is
entered on the user's drivers license. There is a USA federal labor
law restricting their use for specific construction vehicles; although
hydraulic driven power steering vehicles may not fall under this
The American Society of Mechanical Engineers (ASME) publication
B56.1-2004 (and previous ANSI versions), Safety Standard for Low Lift
and High Lift Trucks, addresses modifications to trucks and the use of
Paragraph 4.2.1 requires modifications which may affect the safe
operation of the truck be approved in writing by the truck
Paragraph 4.2.8 requires a spinner knob to be used with steering
mechanisms that prevent road reactions to cause the steering wheel to
spin where one handed operation is required and gives technical
Paragraph 4.2.9 allows the optional use of a spinner knob with
steering mechanisms that prevent road reactions to cause the steering
wheel to spin and gives technical installation specifications.
Similar paragraphs will likely be found in the Canadian Standards
Association (CSA) publication CAN-B335-04, Safety Standard for Lift
Trucks. People in other countries should consult their national
engineering standard organization such as BSI, SAA, SNZ, etc. for
With the exceptions of stand up operated forklifts designed for one
hand operation and the accommodation of a counterbalanced truck for a
disabled person, I can't think of a good reason for the use of a
spinner knob. Controls for lift, tilt, side-shift, and automatic fork
positioning, etc. should not be operated while the truck is in motion.
Activities such as eating, drinking, using a radio, using a cell
phone, etc. should also be prohibited while the truck is in motion.
Both operator's hands, excluding the above exceptions, should be on
the steering wheel while in motion.
Due to the poor lateral stability of forklifts (especially when not
carrying a load), I would not recommend spinner knobs for normal use.
I see spinner knobs as a prelude to a lateral overturn.
Clark Material Handling Company on its web site specifically states
Clark will not approve spinner knobs on hand steering wheels.
You should check with your truck manufacturer to see if they have a
Installing a spinner knob without the manufacturer's approval poses a
very real legal liability as you are making a modification to the
truck which affects safety.
