Description

Traffic signs provide warning and guidance information to drivers 24 hours a day. The provision of this information is especially important during nighttime hours, meaning signs must be visible to drivers during darkness.  This is accomplished through the use of retroreflective sign sheeting, in which the sheeting material reflects light off the sign back to its source (vehicle headlights).  The 2009 edition of the Manual on Uniform Traffic Control Devices (MUTCD) included the provision to implement an assessment or management method to maintain minimum sign retroreflectivity, and the replacement of those regulatory and warning signs that do not meet requirements.  The purpose of these assessment or management methods is to maintain minimum retroreflectivity standards for regulatory and warning signs.

This webinar will provide an overview of the MUTCD minimum sheeting retroreflectivity levels, cover the different assessment and management approaches that agencies can use to monitor sign conditions and ensure compliance, and discuss how to implement/conduct the different methods that are available.
