Where an accused is convicted of culpable homicide arising from a road traffic accident based on negligent driving, section 64(3) of the Road Traffic Act mandates that in addition to any other sentence, the court must: (i) prohibit the accused from driving for a period no shorter than would have been ordered had he been convicted under the Act itself; and (ii) cancel his license if cancellation would have been required under the Act. In plea proceedings for culpable homicide arising from road accidents, the particulars of negligence must be formally put to the accused and admitted, as negligent driving being the proximate cause of death is the essence of the charge. A conviction for culpable homicide based on negligent driving necessarily involves a finding of negligent driving under the Road Traffic Act, triggering the mandatory provisions of section 64(3).
