Chapter 2B. Regulatory Signs
Section 2B.01 Application of Regulatory Signs
Standard:
Regulatory signs shall be used to inform road users of selected
traffic laws or regulations and indicate the applicability of the
legal requirements.
Regulatory signs shall be installed at or near where the regulations apply. The signs shall clearly indicate the requirements imposed by the regulations and shall be designed and installed to provide adequate visibility and legibility in order to obtain compliance.
Regulatory signs shall be retroreflective or illuminated to show the same shape and similar color by both day and night, unless specifically stated otherwise in the text discussion of a particular sign or group of signs (see Section 2A.08).
The requirements for sign illumination shall not be considered to be satisfied by street, highway, or strobe lighting.
Section 2B.02 Design of Regulatory Signs
Support:
Most regulatory signs are rectangular, with the longer dimension
vertical. The shapes and colors of regulatory signs are listed in
Tables 2A-4
and 2A-5, respectively.
Exceptions are specifically noted in the following Sections.
The use of educational plaques to supplement symbol signs is described in Section 2A.13.
Guidance:
Changeable message signs displaying a regulatory message incorporating
a prohibitory message that includes a red circle and slash on a
static sign should display a red symbol that approximates the same
red circle and slash as closely as possible.
Section 2B.03 Size of Regulatory Signs
Standard:
The sizes for regulatory signs shall be as shown in Table 2B-1.
Guidance:
The Freeway and Expressway sizes should be used for higher-speed
applications to provide larger signs for increased visibility and
recognition.
Option:
The Minimum size may be used on low-speed roadways where the reduced
legend size would be adequate for the regulation or where physical
conditions preclude the use of the other sizes.
The Oversized size may be used for those special applications where speed, volume, or other factors result in conditions where increased emphasis, improved recognition, or increased legibility would be desirable.
Signs larger than those shown in Table 2B-1 may be used (see Section 2A.12).
