The Colorado Safety Stop legislation provides a template for counties and municipalities to adopt if they so chose that will allow cyclists to roll through a roadway with a stop sign if the intersection is clear and safe to do so. This policy is commonly referred to as the Idaho Stop and it has been a law in Idaho since 1982. A study in Idaho has shown this practice reduced crashes from 30% to 60%.
