    1. Scope

    This practice covers the use of mobile equipment to measure the retroreflective properties of sign materials such as traffic signs and symbols (vertical surfaces). The mobile retroreflectometer is a vehicle-mounted system that can be used at highway speeds to measure retroreflective properties of traffic signs.

    The need is based on the new US regulations to maintain traffic sign retroreflectivity at specified levels.
