In a prosecution for culpable homicide arising from a road traffic accident, the State must adduce evidence (typically medical evidence such as a post-mortem report) establishing a causal link between the accident and the deceased's death. Without such evidence, a conviction for culpable homicide cannot be sustained, following S v Ramotale 1992 (2) ZLR 397. However, where the evidence establishes negligent driving, a conviction under s 52(2)(a) of the Road Traffic Act may be substituted as a competent verdict. Before imposing mandatory driving prohibitions under s 52(4)(c) of the Road Traffic Act for persons driving commuter omnibuses or heavy vehicles, courts must properly inquire into and record special circumstances. Factors such as steep road conditions, sharp curves, vehicle defects, and their contribution to the accident may constitute special circumstances justifying departure from mandatory sentencing provisions.
