Temp Route Marker Signs are MUTCD compliant (MUTCD M4-7a) and use effective images for traffic and pedestrian safety concerns on highway routes. Temp Route Marker Signs are helpful resources to aid in the protection of the health and safety on roads, and are not an alternative for required protective measures for eliminating or reducing hazards.
Compliance
Section 2D.24 TEMPORARY Auxiliary Sign
Option
The TEMPORARY (M4-7) or the TEMP (M4-7a) auxiliary sign may be used for an interim period to designate a section of highway that is not planned as a permanent part of a numbered route, but that connects completed portions of that route.
Standard
If used, the TEMPORARY or TEMP auxiliary sign shall be mounted directly above the route sign, above a Cardinal Direction sign, or above a sign for an alternate route that is a part of the route designation. TEMPORARY or TEMP auxiliary signs shall be promptly removed when the temporary route is abandoned.
