Drivers were stopped 200 m after passing a warning sign and were tested for recall and recognition of the sign. It was predicted that at night, when the view of the road ahead is severely restricted, sign registration levels would be higher than during the day, when drivers can obtain most of their information directly from their view of the road ahead. The results supported this hypothesis; sign recall levels ranged from 3 to 6% during the day and from 14 to 18% at night. Other variables that were measured (sign content, roadway environments, and subjective levels of fatigue and boredom) had no significant effects on sign registration.
