Speed Limit 40 RM4-1A(40) (600x600mm) corflute Multi-Message Sign (MMS) panel is used in temporary traffic management environments where a 40 km/h speed restriction is specified for roadworks, utility works or changed traffic conditions.

The signface layout, legend and colours follow the applicable AS 1743:2023 design specifications for the RM4-1A(40) code. This regulatory MMS panel is built as a modular component for integration into compatible temporary traffic management frame systems.

UAGS temporary traffic sign corflute panels are manufactured on 6mm UV stabilised corflute using Class 400T full-cube prismatic retroreflective sheeting for temporary work-zone sign applications. The white retroreflective background, black numerals and red annulus support visibility in daytime and low-light traffic management environments.

This panel is designed to fit compatible side slots within a standard Multi-Message Sign Frame No. 1, Multi-Message Sign Frame No. 1, and subject to panel size and frame configuration.

In a typical traffic control sequence, it may be positioned after advance warning panels, such as Road Work Ahead, and before the active work zone where the reduced speed applies, working alongside cones and delineation devices to manage approaching vehicle speeds.
