Warrants (Traffic control devices) (Dcmthw)

Definition
Documents that provide guidance to the designer in evaluating the potential safety and operational benefits of traffic control devices or features. Warrants are not absolute requirements: rather, they are a means of conveying concern over a potential traffic hazard. Also, the criteria by which the need for a safety treatment or improvement can be determined. (Source: AASHTO Glossary)
