Senior v Police

In the case of Senior v Police, the appellant contested their conviction for driving at a speed deemed dangerous to the public under section 46(1) of the Road Traffic Act 1961 (SA). The appellant was caught driving at 156 kilometres per hour along the Southern Expressway, where the speed limit was 100 kilometres per hour. The magistrate's decision to fine the appellant $300 and disqualify their licence for six months was the subject of appeal. The appellant argued that the speed did not constitute a wholly unreasonable and unwarranted danger, and they questioned whether the driver of a motor vehicle could be considered part of the public for the purposes of the statute.

The primary legal issues before the court were the interpretation of the term "dangerous" in the context of driving at an excessive speed and whether the driver themselves could be included within the definition of "the public" for the purposes of the statute. The court needed to determine if the speed at which the appellant was driving constituted a risk that was wholly unreasonable and unwarranted, thereby falling under the prohibition of dangerous driving.

The court found that the appellant's speed of 156 kilometres per hour on a damp but not slippery road, with good visibility, was indeed excessive and created a risk that constituted a wholly unreasonable and unwarranted danger. The court clarified that the term "the public" includes the driver of a motor vehicle themselves, thereby affirming that the appellant's actions were indeed dangerous to the public. This reasoning led the court to uphold the magistrate's decision, dismissing the appeal.

As a result, the appeal was dismissed, and the original conviction and penalty of a $300 fine and six-month licence disqualification stood. The court's decision reinforced the statutory interpretation that excessive speed can constitute dangerous driving, even when considering the driver as part of the public.
