MUTCD compliance affects how agencies plan and operate traffic control devices. These articles examine the 11th Edition, signal face visibility and flashing yellow arrow operating context. Confirm applicable federal, state and local requirements for the specific project.

Review existing signal indications, controller and phasing plans, pedestrian interactions, signal face arrangement and commissioning needs before choosing an arrow module.
Visibility also depends on placement, orientation, backplates, background conditions and maintenance. Evaluate the complete signal face and approach conditions.
See Frontier signal products, technical resources, and contact Frontier for model specific documents.
