The purpose of the present study was to determine what effect (if any)
looking at an automobile's hazard lights has on the direction in whic
h a car is driven. Eight Japanese drivers participated in this experim
ent. Analysis indicated that (a) at night drivers passed closer to a f
orward-facing stationary car than during the day and (b) when instruct
ions were given to look at the hazard lights of a forward-facing stati
onary car, drivers passed closer than when no such instructions were g
iven or when the hazard lights were off. The relationship between look
ing at the visible targets in a visually poor environment and the dire
ction in which a car is driven was discussed.
