Traffic Sign Retroreflectivity

MUTCD Update:
On May 14, 2012 the Federal Highway Administration (FHWA) published two final rules to make things easier for local and state agencies. These rules resulted in two revisions to the 2009 Manual on Uniform Traffic Control Devices (MUTCD) . Revision 1 refers to the use of engineering judgement and studies. Revision 2 refers to compliance dates and historic street name signs. The revisions took effect on June 13, 2012.
