In accidents which involve two-wheeled vehicles the helmet plays a life-saving role, but very little is known
about the motorcycle rider’s perceptions of the helmet. We evaluated the relationships between having been involved in
an accident and dissatisfaction with the helmet and between the perceptions of the motorcycle riders and the objective
features of the helmet. It is a case-control study: riders of motorized two-wheelers who were involved in accidents
(cases) were compared with a sample of riders interviewed as control cases. Information about the driver, the vehicle
and the helmet was collected. To evaluate the relationships, logistic regressions were carried out. Dissatisfaction with
the helmet is complained of by the majority of drivers, but evidence of an association with being involved in an accident
was not found. The most common complaints were about noisiness, followed by the helmet visor. Complaints did not
seem to be associated with the features of the helmet.
