Notes: | 1. Larger sizes may be used when appropriate 2. Dimensions are shown in inches and are shown as width x height |
Guidance:
03 The sizes in the oversized column should be used where engineering judgment indicates a need based on high vehicle operating speeds, driver expectancy, traffic operations, or roadway conditions.
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. The requirements for sign illumination shall not be considered to be satisfied by street, highway, or strobe lighting.
06 All markings shall be visible at night and shall be retroreflective unless ambient illumination provides adequate visibility of the markings.
