Motorcycle Helmet Regulations
The 'Motor Cycles Protective Helmets Regulations 1998' provides legal guidelines for motorcycle and moped helmet compliance. The motorcycle Highway Code also has further guidance on wearing a motorbike helmet and safety gear in the United Kingdom.
Rule 4. Protective Headgear
(1) Save as provided in paragraph (2), every person driving or riding (otherwise than in a sidecar) on a motor bicycle when on a road shall wear protective headgear.

(a) It is a mowing machine; or
(b) It is for the time being propelled by a person on foot.
(3) In this regulation:
'Motor Bicycle' means a two-wheeled motor cycle, whether or not having a sidecar attached, and for the purposes of this definition where the distance measured between the centre of the area of contact with the road surface of any two wheels of a motor cycle is less than 460 millimetres, those wheels shall be counted as one wheel;
'Protective Headgear' means a motorbike helmet which:
(i) Bears a marking applied by its manufacturer indicating compliance with the specifications contained in one of the British Standards (whether or not as modified by any amendment) mentioned in Schedule 2 to these Regulations; or
