Some typical regulatory signs are shown in Part 6 of the MUTCD. 09 An order of priority is especially critical where space is limited for sign installation and there is a demand for several different types of signs. Other devices, or treatments that highlight the sign shape, color, or message: A material that has a smooth, sealed outer surface over a microstructure that reflects light, School Advance Warning Sign (squared bottom corners)*. Support: The functions of signs are to provide regulations, warnings, and guidance information for road users. Each standard sign shall be displayed only for the specific purpose as prescribed in this Manual. All symbols and colors for signs not shown in the "Standard Highway Signs and Markings" book shall follow the procedures for experimentation and change described in Section 1A.10. High legibility (adequately sized letters, symbols, or arrows, and a short legend for quick comprehension by a road user approaching a sign). Word messages should not contain periods, apostrophes, question marks, ampersands, or other punctuation or characters that are not letters, numerals, or hyphens unless necessary to avoid confusion. Overhead sign supports and post-mounted sign and object marker supports should not intrude into the usable width of a sidewalk or other pedestrian facility. Guidance: Divided Highway- Regulatory. If a strip of retroreflective material is used on the sign support, it shall be at least 2 inches in width, it shall be placed for the full length of the support from the sign to within 2 feet above the edge of the roadway, and its color shall match the background color of the sign, except that the color of the strip for the YIELD and DO NOT ENTER signs shall be red. New symbol designs are adopted by the Federal Highway Administration based on research evaluations to determine road user comprehension, sign conspicuity, and sign legibility. The rounded portions of a lower-case letter extend slightly above and below the baselines projected from the top and bottom of such a non-rounded letter so that the appearance of a uniform letter height within a word is achieved. Figure 2A-4 Relative Locations of Regulatory, Warning, and Guide Signs on an Intersection Approach. Department of Transportation. By employing effective wayfinding strategies, designers and facility managers can create user-friendly environments that facilitate smooth and intuitive navigation. The colors of workplace safety - Smart Workplace 15 Unless otherwise provided in this Manual for a specific sign, and except as provided in Paragraph 16, telephone numbers of more than four characters should not be displayed on any sign, supplemental plaque, sign panel (including logo sign panels on specific service signs), or changeable message sign. Guidance: Support: A supplementary sign located on the left-hand side of the roadway may be used on a multi-lane road where traffic in a lane to the right might obstruct the view to the right. Motorist services and recreation signs, for example, include signs for tent camping, food, lodging, telephone, hospital, emergency services, information . Option: Guidance: Therefore, this Manual sometimes includes the practice of using educational plaques to accompany new symbol signs. Signs | Driving Information | DriversEd.com Guide signs show route designations, destinations, directions, distances, services, points of interest, and other geographical, recreational, or cultural information. 06 Highway agencies may exclude the following signs from the retroreflectivity maintenance guidelines described in this Section: Standard: White or red, if used with STOP or YIELD signs. White or yellow, if used with school area signs. Option: If a shoulder wider than 6 feet exists, the minimum lateral offset for post-mounted signs should be 6 feet from the edge of the shoulder. The minimum lateral offset is intended to keep trucks and cars that use the shoulders from striking the signs or supports. Insufficient space for post-mounted signs. Are outside the clear zone unless placed on a breakaway or yielding support (see. Highway construction and maintenance signs fall into the same three major classifications as other signs, namely regulatory, warning, and guide signs. As standalone signs, they serve a specific role; as part of the greater . 07 The clear zone is the total roadside border area, starting at the edge of the traveled way, available for use by errant vehicles. The expected sign life is based on the experience of sign retroreflectivity degradation in a geographic area compared to the minimum levels. 17 Figure 2A-2 illustrates some examples of the mounting height requirements contained in this Section.

Regulatory: These communicate what you should do and control traffic flow. Fractions shall be displayed with the numerator and denominator diagonally arranged about the solidus (slanted line or forward slash). Measured Sign RetroreflectivitySign retroreflectivity is measured using a retroreflectometer. 09 When an Interstate route is displayed in text form instead of using the route shield, a hyphen should be used for clarity, such as "I-50.". Regulatory signs are usually rectangular and carry a black legend and border on a white background. Signs required by road conditions or restrictions shall be removed when those conditions cease to exist or the restrictions are withdrawn. Evaluation, approval, and installation of traffic signals . The provisions of this Section shall apply unless specifically stated otherwise for a particular sign or object marker elsewhere in this Manual. Signs that are visually identified by the inspector to have retroreflectivity below the minimum levels should be replaced. If used, the LEDs shall have a maximum diameter of 1/4 inch and shall be the following colors based on the type of sign: If flashed, all LED units shall flash simultaneously at a rate of more than 50 and less than 60 times per minute. 12 Overhead sign supports and post-mounted sign and object marker supports should not intrude into the usable width of a sidewalk or other pedestrian facility.

One of the factors considered when determining the appropriate spacing shall be the posted or 85th-percentile speed. Overhead signs should be used on freeways and expressways, at locations where some degree of lane-use control is desirable, and at locations where space is not available at the roadside. Light Emitting Diode (LED) units may be used individually within the legend or symbol of a sign and in the border of a sign, except for changeable message signs, to improve the conspicuity, increase the legibility of sign legends and borders, or provide a changeable message. When the height of a lower-case letter is specified or determined from the prescribed ratio, the reference is to the nominal loop height of the letter. Examples of heights and lateral locations of signs for typical installations are illustrated in Figure 2A-2, and examples of locations for some typical signs at intersections are illustrated in Figures 2A-3 and 2A-4. Signs requiring separate decisions by the road user shall be spaced sufficiently far apart for the appropriate decisions to be made.

The uniformity of the sign design shall be maintained without any decrease in visibility, legibility, or driver comprehension during either daytime or nighttime conditions. Information regarding color coding of destinations on guide signs, including community wayfinding signs, is contained in Chapter 2D. Because regulatory and warning information is more critical to the road user than guidance information, regulatory and warning signing whose location is critical should be displayed rather than guide signing in cases where conflicts occur. 06 All supports should be located as far as practical from the edge of the shoulder. The actual loop height of a rounded lower-case letter is slightly greater than the nominal loop height and this additional height is excluded from the expression of the lower-case letter height. The amendment postpones the notification deadline and gives manufacturers more options on how to report. Regulatory signs used in construction and maintenance zones use the normal standard colors, shapes, and messages. They include Stop Signs, Speed Limit Signs, One Way Signs, Turn Prohibition Signs, Do Not Enter Signs, and other signs that convey the rules of the road to motorists.

As a quick reference, common uses of sign colors are shown in, Whenever white is specified in this Manual or in the "Standard Highway Signs and Markings" book (see. 03 For alleys with restrictive physical conditions and vehicle usage that limits installation of the minimum size sign (or the Conventional Road size sign if no Minimum size is shown), both the sign height and the sign width may be decreased by up to 6 inches. On curved alignments, the angle of placement should be determined by the direction of approaching traffic rather than by the roadway edge at the point where the sign is located. Employees of highway, law enforcement, and other public agencies whose duties require that they travel on the roadways should be encouraged to report any damaged, deteriorated, or obscured signs, gates, or object markers at the first opportunity. Yield Sign what regulatory sign is this? Option: For non-diamond shaped signs such as W14-3 (No Passing Zone), W4-4P (Cross Traffic Does Not Stop), or W13-1P, -2, -3, -6, -7(Speed Advisory Signs), use largest sign dimension to determine proper minimum retroreflectivity level. Standard: 01 Overhead signs should be used on freeways and expressways, at locations where some degree of lane-use control is desirable, and at locations where space is not available at the roadside. The Sign Catalog is for informational purposes only. The measure clarifies and improves provisions set out by 38 M.R.S. OceanGate Was Warned of Safety Concerns with Titanic Mission - The New 08 With the increase in traffic volumes and the desire to provide road users regulatory, warning, and guidance information, an order of priority for sign installation should be established. Consider the challenge sign designers face. They are used to help road users drive safely by reinforcing traffic laws and regulations. 10 The uniformity of the sign design shall be maintained without any decrease in visibility, legibility, or driver comprehension during either daytime or nighttime conditions. Traffic signs are one of the three basic types of traffic control devices, the others being markings and signals. Desirable attributes include: Standardized colors and shapes are specified so that the several classes of traffic signs can be promptly recognized. 1 The minimum maintained retroreflectivity levels shown in this table are in units of cd/lx/m2 measured at an observation angle of 0.2 and an entrance angle of -4.0. Standard: Figure 2A-2 Examples of Heights and Lateral Locations of Sign Installations, Figure 2A-3 Examples of Locations for Some Typical Signs at Intersections. Each of these has two subcategories. Letter height is expressed in terms of the height of an upper-case letter.
