129. Wearing of protective headgear.
Every person driving or riding (otherwise than in a side car, on a motor cycle of any class or description) shall, while in a public place, wear a protective headgear of such description as may be specified by the State Government by rules made by it in this behalf, and different descriptions of headgears may be specified in such rules in relation to different circumstances or different class or description of motor cycles:
Provided that the provisions of this section shall not apply to a person who is a Sikh, if he is, while driving or riding on the motor cycle, in a public place, wearing a turban:
Provided further that the State Government may, by such rules, provide for such exceptions as it may think fit.
Explanation.--"Protective headgear" means a helmet which,--
by virtue of its shape, material and construction, couldreasonably be expected to afford to the person driving or riding on a motor cycle a degree of protection from injury in the event of an accident; and
is securely fastened to the head of the wearer by means of straps or other fastenings provided on the headgear.
