Pedestrians
The formulation of the duty in terms which require that a road be safe not in all circumstances but for users exercising reasonable care for their own safety is even more important where, as in Ghantous, the plaintiff was a pedestrian. In general, such persons are more able to see and avoid imperfections in a road surface. It is the nature of walking in the outdoors that the ground may not be as even, flat or smooth as other surfaces. As Callinan J points out in his reasons in Ghantous, persons ordinarily will be expected to exercise sufficient care by looking where they are going and perceiving and avoiding obvious hazards, such as uneven paving stones, tree roots or holes. Of course, some allowance must be made for inadvertence. Certain dangers may not readily be perceived because of inadequate lighting or the nature of the danger (as in Webb v South Australia), or the surrounding area (as in Buckle, where the hole was concealed by grass). In such circumstances, there may be a foreseeable risk of harm even to persons taking reasonable care for their own safety. These hazards will include dangers in the nature of a `trap' or, as Jordan CJ put it, `of a kind calling for some protection or warning' [Searle v Metropolitan Water, Sewerage and Drainage Board]. In Romeo, Toohey and Gummow JJ noted in a different context that the care to be expected of members of the public is related to the obviousness of the danger. Kirby J pointed out in the same case that even an occupier of premises `is generally entitled to assume that most entrants will take reasonable care for their own safety'. Each case will, of course, turn on its own facts.[45]
Inspections
Cases respecting inspections for dangerous conditions have been determined by the dichotomy between misfeasance and non-feasance. A 'highway authority' was not liable if it failed to conduct inspections but, seemingly, was liable if it began remedial work in response to the discovery by inspection of defects or, possibly, even once it discovered the existence of those defects. These cases usually involved 'non-feasance', as an inspection typically discloses a situation which is unsafe and needs repair. Allied to them are cases in which a danger first manifests itself when the road surface, or a structure, collapses or gives way either under the plaintiff or shortly before it is crossed.
Where the danger could not reasonably be suspected to exist, or could not be found except by taking unreasonable measures, generally there will be no breach of duty by the authority. On the other hand, there will be a breach of duty where an authority fails to take reasonable steps to inspect for such dangers as reasonably might be expected or known to arise, or of which the authority has been informed or made aware, and, if they are found, fails to take reasonable steps to correct them. In the cases, the danger usually manifests itself in decayed beams or supports of bridges, or drains or culverts, or other structures supporting a road or its surface. The reports of Macpherson, Buckle and Gorringe all disclose insufficient facts to determine the reasonableness of the inspections which did take place or of the failure to inspect and ascertain the existence of the danger which caused the injury to the plaintiffs in those cases.[46]
