School (S) Series

School signs are used to advise the driver of an area where children are present and to insure the safety of children as they travel to and from school.
The 2009 Edition of the MUTCD (Manual On Uniform Traffic Control Devices),  Section 7B-07 states "School Warning Signs shall have a fluorescent yellow-green background unless  otherwise provided in the MUTCD for a specific sign".  On January 22, 2015, all School Signs must meet new retroreflectivity requirements as stated in the MUTCD.  We at Luther Sign Co. have begun making all our School Signs to meet this requirement by using 3M High Intensity Prismatic reflective sheeting.
In 2009, we began dating the backs of our School Signs to help our governmental customers comply with the new federal requirements.
