Easy AWS/ANS Sign Requirement Helper
Advanced Notification Signs (ANS) and Advanced Warning Signs (AWS) are signs described by OTM Book 7 that are meant to do exactly as they are named, give drivers advanced warning/notification of road restritions. There does tend to be a lot of confusion surrounding these signs and when they are specifically required because of their similar naming. It doesn’t help that the requirements for these types of sign are not quite as clear as many of the signs in Book 7 for temporary conditions.Below we have created a form to simplifiy this. Simply enter some project details and you will be provided the sign requirements and citations from Book 7 for reference.
