2 Del. Admin. Code § 2A.12
Current through Register Vol. 28, No. 5, November 1, 2024
Standard:
01 (DE Revision) Symbol designs shall in all cases be unmistakably similar to those shown in this Manual, in the "Standard Highway Signs and Markings" book (see Section 1A.11), and in the Delaware Standard Signs book. Support:
02 New symbol designs are adopted by the Federal Highway Administration based on research evaluations to determine road user comprehension, sign conspicuity, and sign legibility.03 Sometimes a change from word messages to symbols requires significant time for public education and transition. Therefore, this Manual sometimes includes the practice of using educational plaques to accompany new symbol signs. Guidance:
04 New warning or regulatory symbol signs not readily recognizable by the public should be accompanied by an educational plaque. Option:
05 Educational plaques may be left in place as long as they are in serviceable condition.06 State and/or local highway agencies may conduct research studies to determine road user comprehension, sign conspicuity, and sign legibility. Guidance:
07 Although most standard symbols are oriented facing left, mirror images of these symbols should be used where the reverse orientation might better convey to road users a direction of movement. Standard:
08 A symbol used for a given category of signs (regulatory, warning, or guide) shall not be used for a different category of signs, except as specifically authorized in this Manual.09 Except as provided in Paragraph 11, a recreational and cultural interest area symbol (see Chapter 2M) shall not be used on streets or highways outside of recreational and cultural interest areas.10 A recreational and cultural interest area guide sign symbol (see Chapter 2M) shall not be used on any regulatory or warning sign on any street, road, or highway. Option:
11 A recreational and cultural interest area guide sign symbol (see Section 2M.04) may be used on a highway guide sign outside of a recreational and cultural interest area to supplement a comparable word message for which there is no approved symbol for that message in Chapters 2B through 2I or 2N. Support:
12 Section 2M.07 contains provisions for the use of recreational and cultural interest area symbols to indicate prohibited activities or items in non-road applications.2 Del. Admin. Code § 2A.12
