The seasonal variation and age distributions of road deaths and of suicides in 1969 & 1970 were compared, as were the incidences of single-car, single-occupant deaths & single-car, multiple-occupant deaths occurring in different road conditions.

While undoubtedly a few were intentional deaths it was concluded that the proportion was not large enough to affect the reported suicide rate. (5 refs.)
