REDUCED-VISIBILITY (FOG) ACCIDENTS ON LIMITED-ACCESS HIGHWAYS

The National Transportation Safety Board has undertaken the investigation of several highway accidents in which the presence of fog was a contributing factor. The study is the culmination of what the Safety Board has learned through its accident investigations, public hearing, fog symposium, and review of pertinent research studies and literature relative to reduced visibility problems caused by fog. The study reviews the various approaches that have been taken to prevent fog accidents or that have a bearing on the problem; namely, driver education, fog detection and guidance systems, environmental control, highway department procedures, vehicle and highway lighting, enforcement; and postaccident control. In light of this finding, the study includes recommendations intended to alleviate the problem from several directions, namely, driver education, police-highway department procedures for closing highways, enforcement of the basic speed rule as related to fog accidents, mutual-assistance pacts for postaccident control of accidents, implementation of Highway Safety Programs Standards and Federal Highway Administration plans to develop highway guidance systems.
