Samenvatting
A study was made of 488 cases of two-wheel vehicle operator injuries over the period 1974- 1976. The study shows the great importance that must be given to two-wheel vehicle casualties who represent a very high proportion of the lesions recorded in national statistics, which obviously do not concern themselves, except for the fastest machines, with the safety measures in force at present, particularly enabling the protection of the lower limbs. Improvements in the manufacture of helmets are desirable.
