TEXT:

A customer has requested that a 4 inch (100 mm) wide retroreflective sheeting be placed along the side of a trailer he is ordering. The manufacturer is reluctant to provide this width of sheeting since the rule states in S5.7.1.3(d) that Grade DOT-C2 sheeting shall have a width of 50 mm. This provides no tolerance nor does it provide a minimum.

May a manufacturer install 4 inch (100 mm) wide retroreflective sheeting instead of 2 inch (50 mm) sheeting on the side of new trailers?
