Three out of four persons disabled by road traffic crashes suffer from mild disability.
The moderate/severe disability rate on the Capacity Severity Index is 0.6 per thousand for ages >16 years, decreasing to 0.4 per thousand on the Performance Severity Index.
Mental and nervous system impairments are associated with greater severity of disability.
The majority of moderately/severely/completely disabled persons need technical aids, personal assistance and family support.
