The guy told me i just had to make sure it was reflective. What is the difference between.
engineer grade reflective
high intensity reflective
This is a code sign and must conform to certain specifications.
One is the size of the lettering to the speed limit...
Typeface...
Color...
And reflective specs.
Typical engineer grade vinyl is not compliant to MUTCD on a street name sign.
The whole panel has to be reflective, the high intensity film is what you need. So you would get a blank that has the correct reflective on it, then get the 3M trans green film and cut out the lettering and apply that to the panel.
