This is a summary of the procedures and findings of a study of highway signs to warn of restricted sight distance due to crest vertical curves. Driver awareness, understanding, and response to the existing LIMITED SIGHT DISTANCE (LSD) sign and several alternative signs were measured. Following a study of performance requirements, a large number of preliminary alternative sign designs were tested in a laboratory setting. Further laboratory testing of the five most promising designs was conducted to assess driver comprehension and assimilation. The two most promising verbal and symbol alternatives were next evaluated in a controlled field study and an observational field study, conducted at several vertical curves on two-lane rural roads.
