1.4 Definitions
A.Retroreflective Sheeting 1. Sheeting – The retroreflective or non- reflective material that comprises the background, legend (word messages and symbols), and border.
2.Sheeting Components – The matched component products required for the manufacture of highway signs consist of the sheeting, cutout letters and borders, adhesives, inks , and overlay films.
3.Permanent Traffic Signs - Include sign installations that are in their final configuration and that are expected to have a multi -year life. Examples include freeway guide signs, regulatory signs, warning signs, barrier markers, crash cushion markers, freeway crossover markers and delineation.
4.Work Zone Standard Signs – MUTCD and Department standard application signs including but not limited to Road Work Ahead, Work Zone Speed Limit, Flagger Symbols, Business Access, and Regulatory signing within the work zone.
5.Work Zone Project Specific Signs – Signs that have legends specific to the project and that cannot be reused on a future project. Examples include: “Alder Street closed from 1st to 2nd Avenue – use Birch Street” or project notification signs. These are typically used for only one construction season.
6.Flexible Work Zone Devices – Include such devices as roll up signs, cones, tall cones, and flags with retroreflective sheeting.
7.Work Zone Channelization Devices – Include such devices as drums, vertical panels, barricades, tubular markers, and pavement marking tabs.
