STATISTICAL PROBLEMS IN ESTABLISHING REDUCED VISUAL PERFORMANCE AS A CAUSE OF ACCIDENTS

UEMBER STATISTISCHE PROBLEME BEI DER ERMITTLUNG VON EINGESCHRAENKTER SEHLEISTUNG ALS UNFALLURSACHE

People with defects in the region of the cornea and the lens in both eyes must be designated as unfit to drive, whereas people with the same defects in one eye are significantly impaired in darkness. A study of the percentage of unfit (as regards eyes) drivers, the dependence of accident rate on visual performance of drivers and the significance of reduced visual ability in accidents showed that people with defective vision are more likely to have accidents. It is concluded that one-eyed drivers cause more accidents than normal drivers. Further breakdown into proto and deutero defects showed that those with proto defects were more at risk. An evaluation of another study of drivers who had driven for 10-50 years without an accident showed that visual defects are only one of many causes. (TRRL) abstract for the conference is IRRD no 311241.
