1. A motorist has a duty to reduce speed and exercise caution when children are observed within the vicinity of the road, as children have a propensity for impulsive and irrational action requiring greater care than is otherwise necessary (applying S v Duri 1989 (3) ZLR 111 (SC)). 2. An appellate court will only interfere with a trial court's sentencing discretion if the sentence is disturbingly inappropriate, not merely because it can, but because it must (applying S v Ramushu SC-25-93). 3. Being a first offender is not in itself sufficient reason to interfere with a court's sentencing discretion or to preclude effective custodial sentences. 4. In culpable homicide cases arising from driving offences, trial courts must make findings on the degree of negligence before assessing appropriate sentence, though substance prevails over form where such findings are effectively made.
