Means of stimulating the voluntary use of

The Ministry of Transport has asked SWOV to gather knowledge about the possibilities of promoting

voluntary use of bicycle helmets in the . SWOV carried out three stud fes: a literature study of

the developments abroad, a study of the potential contribution of various parties and organisations towards

promoting the use of helmets and an interview study held amongst some potentia I cyclist target groups.

The private (public interest) organisations presently do not wish to stimulate the use of cycle helmets through controlling policy. They make the following critical comments: Stimulating the use of the cycle helmet: - could have a negative side effect in that an unjustified link may be established between cycling and danger; - could have a negative side effeL1 in that cycle IIse may drop; - does not fit well into cllrrent govemmem policy, which pnillarily focllses on the prevention of accidents and on promotion of bicycle IIse.
