Option:

04 Signs and plaques larger than those shown in Table 5A-1 may be used (see Section 2A.11).

Standard:

05 All signs shall be retroreflective or illuminated to show the same shape and similar color both day and night, unless specifically stated otherwise in other applicable Parts of this Manual.
