MUTCD Library
The GRX uses the MUTCD library to identify the particular type of sign that is being inspected and to
check that the reflectivity of the sign is above the minimum maintain reflectivity level.
MUTCD (Manual on Uniform Traffic Control Device) is a national standard, which encompasses a
library of all national traffic signs in the United States.
During the use of the GRX, the instrument will ask you to choose the relevant sign type according to
the below table (source:
