Guidelines for Selecting Sign Sheeting to Meet Minimum Retroreflectivity Levels have been developed to assist transportation agencies in selecting sign sheeting types and maintenance strategies to provide sufficient levels of retroreflectivity for night-time drivers. This guideline provides guidance for minimum levels of sign retroreflectivity adopted for the Manual of Uniform Traffic Control Devices for Canada.

The guidelines consist of the following sections:

·         Section 1 provides background information on the subject;

·         Section 2 describes the various sheeting types available for manufacturing signs;

·         Section 3 provides an overview of retroreflectivity concepts;

·         Section 4 describes factors affecting sheeting selection;

·         Section 5 provides specific guidelines for various sign classes and delineators; and

·        Section 6 describes options for maintaining retroreflectivity levels for traffic signs and delineators.
