In an effort to determine possible relationships between lateral vision and accident involvement, the visual fields of over 52,000 North Carolina drivers were measured. The results indicated that: (1) Relatively accurate visual field data can be gathered in the field of driver license examiners; (2) Less than one percent of North Carolina drivers have total visual fields of 120 degrees or less; (3) Visual field is related to age with a higher proportion of older drivers haveing "limited" visual fields; (4) Overall two year retrospective accident experience of those with "limited visual fields" (140 degrees or less) does not differ from drivers with "normal" fields of view (greater than 160 degrees); (5) When examinees are divided into five age categories (less than 25 years, 26-40 years, 41-69 years, 61-70 years, greater than 70 years) there is again no significant evidence that narrower visual fields are related to higher accident involvement for any age group; and (6) Restricted visual fields may be slightly related to a higher proportion of side-collisions. While results should not be interpreted as meaning that peripheral vision is unimportant in the operation of a vehicle, they do indicate that use of this particular tool as a driver screening measure should not be expected to result in any appreciable accident savings. /Author/
