## Revisions to Chapter 2D – Guide Signs forConventional Roads

**Revisions to**** Chapter 2D – ****Guide Signs for****Conventional Roads**

**Notes:**
The following slides discuss the significant proposed revisions in Chapter 2D.

## Provisions for use of pictographs on guide signs

**Exceeds max size**

**Notes:**
 Provisions regarding the use of pictographs on guide signs are being added, including a restriction on their maximum size so that they do not overly detract from the primary legend of the signs, reflecting recent Official Interpretations. The recommended maximum size is no larger than that of a route marker on a guide sign.  In the example shown at the lower right, the pictograph size exceeds the maximum recommended size. 

## New guide signs for roundabouts

**Notes:**
A new section is being added regarding the use of destination signs at roundabouts.  New curved-stem arrows that represent the intended driver paths to destinations involving left-turn movements are being added for use on guide signs on roundabout approaches.  An option is being added that allows diagrammatic route sign formats to be used on roundabout approaches. 

## Route and auxiliary signs combined on a green background

**Route and auxiliary signs combined on a green background**

**Notes:**
A new recommendation is being added to clarify that if a route sign and its auxiliary sign messages are combined on a single guide sign, the background color of the sign should be green.  A new requirement is also being added that auxiliary signs shall not be mounted directly on a guide sign, such as in the example that is shown in the upper right. 

## For optional use above confirming route sign at the start of a route

**Notes:**
A new BEGIN auxiliary sign is being added for use above the confirming route marker at the start of a route to provide additional helpful information to road users, based on the Sign Synthesis Study that revealed that several States use an auxiliary BEGIN sign above the confirming route marker at the start of a route. 

## New TOLL auxiliary sign

**Notes:**
A new TOLL auxiliary sign is being added to inform road users that a numbered route is a toll facility. 

## New ETC only auxiliary sign

**Notes:**
A new Electronic Toll Collection Only auxiliary sign and NO CASH plaque are being added to inform road users that a highway is restricted to use only by ETC-equipped vehicles.  These signs would be used in a route sign assembly.

## Shields and trailblazer assemblies for named trails or un-numbered routes

**Shields and trailblazer assemblies for named trails or un-numbered routes**

**Notes:**
GUIDANCE is being added to recommend that if shields or other similar signs are used to provide route guidance in following a trail or an important un-numbered route, they should be designed in accordance with the sizes and other design principles for route signs, such as those described in Sections 2D.10 through 2D.12.  This change addresses situations where route signs are used for named trails and important routes that do not have route numbers. 

## Lane designation auxiliary signs

**Notes:**
New LEFT LANE, CENTER LANE, and RIGHT LANE auxiliary signs are being added that may be mounted below route signs in route sign assemblies to inform road users regarding which lane to use to access a particular numbered route and direction.  The Sign Synthesis Study found that at least seven States use M6 auxiliary signs stating “Left Lane,” “Center Lane,” or “Right Lane” below route signs in route sign assemblies.  This can be an economical alternative to one or more larger green guide signs in certain situations. 

## Combination Lane-Use and Destination Overhead Guide signs

**Notes:**
New Combination Lane Use/Destination Overhead Guide signs are being added that combine regulatory lane use information with destination information on a single guide sign or sign assembly to assist unfamiliar drivers in determining which lane or lanes to use for a particular destination.
At complex intersections involving multiple turn lanes, multiple destinations, service roads, and/or various constraints often found in urban areas that can limit the ability to use of a series of advance signs, many States have found it necessary to combine regulatory lane use information with destination information onto a single guide sign or sign assembly.  However, there is no consistency or uniformity in the colors used, the sign design layouts, or other aspects of these signs. The uniform design for this type of sign provides consistency for road users. 

## Route shield may be used on a street name sign

**Notes:**
A new option is being added allowing the use of a route shield on a Street Name sign to assist road users who might not otherwise be able to associate the name of the street with the route number. The Sign Synthesis Study found that several agencies incorporate route shields into Street Name signs on streets that are part of a U.S., State, or county numbered route.  Typically route sign assemblies are only provided on intersecting roads that are also numbered routes, and on some very major unnumbered streets within cities.  Including a route shield within the Street Name sign provides additional information for traffic on the lesser streets that intersect the numbered route.  This is helpful to unfamiliar road users who may be attempting to find their way back to a numbered route and who do not recognize the street name.

## New table for letter heights on Street Name signs

**Notes:**
A new table is being added that contains information regarding the letter sizes to be used on Street Name signs based on the mounting type, road classification, and speed limit.  No changes are proposed in the letter sizes from those recommended in the 2003 MUTCD.

## Only alternatives to green          Street Name sign background color will be blue, brown, or black

**Notes:**
A new requirement is being added to limit the only acceptable alternatives to green for the background color of Street Name signs to blue, brown, or black, to eliminate a wide variation in practice among jurisdictions. Sometimes inappropriate colors are being used, because these are colors reserved for other traffic control device messages, or the colors used have poor contrast ratio between legend and background. The alternatives allow flexibility for communities to express their unique identity.

## Recommended order of                 2 street names on                    advance street name sign

**Notes:**
New recommendations are being added regarding the order in which street names should be displayed on an Advance Street Name sign to provide improved consistency in this type of signing.

## On multi-lane conventional road approaches to interchanges, guide signs identifying the direction of turn or lane to use for each ramp shall be provided

**On multi-lane conventional road approaches to interchanges, guide signs identifying the direction of turn or lane to use for each ramp shall be provided**

**Notes:**
The information in existing Section 2E.49 regarding the signing on conventional roads on approaches to interchanges is being relocated to Chapter 2D.  In this relocated section, an existing recommendation is being changed to a requirement that on multi-lane conventional road approaches to any freeway interchange, guide signs shall be provided to identify which direction of turn is to be made for ramp access and/or which specific lane to use to enter each direction of the freeway. This information is critical for drivers on a multi-lane approach to an interchange because it allows drivers to choose the proper lane in advance and reduces the need to make last-second lane changes close to the entrance ramp.  The information in existing Section 2E.50 regarding the use of freeway entrance signs is also being relocated to Chapter 2D. 

## New alternative parking wayfinding sign

**Notes:**
A new Parking Wayfinding sign is being added to be used as an alternative to the existing Parking Area directional sign and to give agencies a parking guide sign that can be consistently used in community wayfinding programs. This new sign is consistent with the widespread use of the blue background and white P as a parking wayfinding symbol throughout Europe and at many airports and institutional sites in the United States.

## New provisions on the design and use of                       community wayfinding signs

**Notes:**
New provisions are being added regarding the use of community wayfinding guide signs to direct tourists and other road users to key civic, cultural, visitor, and recreational attractions and other destinations within a city or a local urbanized or downtown area. Many of the cities currently using community wayfinding signs are using different colors, design layouts, fonts, and arrows, and many of these signs are not well designed to properly serve road users.  This new section provides a uniform set of provisions for design and locations of these signs based on accepted sign design principles, to achieve consistency for road users. 

## Guide signs for truck lanes, passing lanes, and climbing lanes

**Notes:**
New provisions are being added regarding truck, passing, and climbing lane guide signs to be consistent with the proposed elimination from Chapter 2B of existing regulatory signs used for this purpose.

## Slow vehicle turn-out            advance guide sign

**Notes:**
A new Slow Vehicle Turn-Out sign is being added to inform drivers of the distance to the next turn-out location.

## Revisions to Chapter 2E – Guide Signs forFreeways and Expressways

**Revisions to**** Chapter 2E – ****Guide Signs for****Freeways and Expressways**

**Notes:**
The following slides discuss the significant proposed revisions in Chapter 2E.

## Down arrows shall always be vertical and positioned directly over the approx. center of each applicable lane

**Down arrows shall always be vertical and positioned directly over the approx. center of each applicable lane**

**Notes:**
A requirement is being added that down arrows on overhead signs shall always be vertical and positioned directly over the approximate center of the applicable lane. Some States have installed overhead guide signs with downward slanting arrows that are not centered over the appropriate lanes, but pointing toward the center of a lane, only for the purpose of reducing sign size.  Arrows designed and oriented in this fashion are confusing to drivers because they imply movement out of a lane.  The use of more than one down or diagonal arrow pointing to the same lane is also being prohibited for the same reasons.  The diagonal down arrows in this photos will no longer be allowed. 

## LEFT plaques required for numbered and un-numbered exits to the left

**Notes:**
Because left exits are often not expected, the existing recommendation to place the word “LEFT” on a black-on-yellow panel at the top of the exit number plaque to alert drivers that an exit is to the left is being changed to a requirement.  A new black-on-yellow LEFT plaque is also being added and is required to be placed above the top left edge of Advance Guide and Exit direction signs for non-numbered exits to the left. 

## Significant revisions on diagrammatic sign design and use

**Significant revisions on diagrammatic sign design and use**

**Lane lines on arrow shaft -- too subtle!**

**Notes:**
Significant changes are being made to the provisions regarding diagrammatic signs for multi-lane exits that have an optional exit lane that also carries the through road and for splits that include an optional lane.  The existing diagrammatic sign design that attempts to illustrate optional lane use via lane lines on an arrow shaft is too subtle to be easily recognized and understood by many road users, especially older drivers. 

## New diagrammatic signs required for “option-lane” exits and splits and will feature an up arrow over each lane

**New diagrammatic signs required for “option-lane” exits and splits and will feature an **_**up arrow**_** over each lane**

**Notes:**
The revised provisions for multi-lane exits that have an optional exit lane that also carries the through road, and for splits that include an optional lane, specify a design that features an upward arrow per lane.   This reflects Older Driver research and has been confirmed by recent studies as having superior performance, in terms of providing a longer decision sight distance and higher rates of road user comprehension. The FHWA believes that the up arrow per lane style of diagrammatic signs, including the appropriate use of EXIT ONLY sign panels, is the clearest and most effective method of displaying to road users the essential information about the proper and allowable lanes to use to reach their destinations. Because of the nature of the combination of lane use and geometry, the FHWA believes that the proposed new type of diagrammatic signing should be mandatory for exits and splits with “option lanes”.  This also includes certain types of cloverleaf interchanges, where: (1) the outer (non-loop) exit ramp of a cloverleaf is a multi-lane exit having an optional exit lane that also carries the through route, and (2) a cloverleaf interchange that includes a collector-distributor roadway that is accessed from the main roadway by a multi-lane exit having an optional exit lane that also carries the through route. 

## For lane drops without an           “option lane”, EXIT ONLY panel with down arrow(s) required on all overhead advance guide signs

**Notes:**
The existing recommendation to use an EXIT ONLY (down arrow) sign panel on all overhead Advance Guide signs for exits with lane drops that do not have an “option lane” is being changed to a requirement, as this is the clearest and most effective method of displaying to road users the essential information about this type of lane drop and about the proper lane(s) to use to reach their destination. This change provides consistency with other changes in the Manual, especially related to the use of arrows that are better understood by older drivers.  

## For lane drop without            “option lane”, Exit Direction sign shall have EXIT ONLY panel with upward diagonal arrow

**Notes:**
The use of upward diagonal black arrows within an EXIT ONLY panel at the bottom of the Exit Direction signs for such interchanges is also being required to more clearly reinforce the lane drop while still providing upward diagonal arrows in the direction of the exit.

## An advisory speed legend may be added to an Exit Direction sign

**Notes:**
A new option is being added that permits the use of an advisory speed legend at the bottom of an Exit Direction or diagrammatic sign to supplement, but not to replace, the post-mounted exit or ramp advisory speed warning signs, to provide more advance notice or extra emphasis for ramps with an especially low advisory ramp speed, typically because of curvature. 

## New requirement for exit numbering by reference location 

**Space required between****                     number and letter**

**Notes:**
The option of using consecutive exit numbering is being replaced with a new requirement that interchange exit numbering use the reference location exit numbering method.  Only 8 of the 50 States still use consecutive exit numbering and the vast majority of road users now expect reference location exit numbering. The FHWA believes that road users will be best served by nationwide uniformity of exit numbering using the reference location method.
Also, the previous requirement is being clarified that suffix letters that are included on the exit number plaque or an Exit Gore sign shall be separated from the exit number by a space having a width of at least half of the height of the suffix letter in order to enhance the legibility of the exit number and avoid confusion, as the “B” suffix frequently looks like an “8” when viewed from a distance.  In addition, a new requirement is being added that makes it clear that if suffix letters are used for exit numbering, an exit of the same number without a suffix letter cannot be used.  

## Type 1             object markers may be used on             exit gore             sign supports

**Notes:**
A new option is being added that allows the use of Type 1 object markers on Exit Gore sign supports to improve the visibility of the gore for exiting drivers, based on recommendations from the Older Driver handbook. 

## New guide signs for preferential lanes

**Notes:**
The existing provisions regarding preferential lane guide signs are being substantially edited and reorganized to improve consistency and understanding by grouping like material together, and new and revised technical provisions and designs for various preferential lane guide signs are included. This was the subject of a policy memo that was issued earlier this year and posted on the MUTCD website. 

## Guide signs for toll plazas and open-road ETC lanes

**Notes:**
New provisions are being added to describe the design and application of guide signs at conventional toll facilities and for Electronic Toll Collection (ETC) facilities, including open road ETC lanes. 

## New guide signs and symbols for toll plaza canopies

**Notes:**
As a part of these changes, new symbols that denote exact change and attended lanes are being added for use in toll plaza signing in order to help road users more quickly identify the proper lane(s) to use for the type of toll payment they will use. The new symbols are similar to those already in use for these purposes on some toll facilities in the U.S. as well as in Europe and Asia, and the FHWA also believes that such symbols will also aid in understanding by international travelers. 

## New symbol identifying nationally interoperable ETC systems, for future use

**Notes:**
A new symbol that denotes that a toll facility’s electronic toll collection (ETC) payment system is nationally interoperable with all other ETC payment systems is also being added for future use when this interoperability becomes available in the next few years. It will take a number of years thereafter for all toll operators to transition to full interoperability and, during that transition period, there will be a need for signing to indicate to road users that a particular toll facility’s payment system is nationally interoperable. The FHWA believes that it is in the best interest of uniformity, safety, and road user convenience for a standard symbol to be adopted prior to the transition period so that it is available when needed.

## New guide signs for managed and ETC-only facilities

**Notes:**
New information is being added to incorporate new provisions regarding managed lanes and lanes reserved only for vehicles equipped for Electronic Toll Collection, which are forms of preferential lanes 

## Revisions toChapter 2F – General Service Signs(relocated from Chapter 2E)

**Revisions to****Chapter 2F – ****General Service Signs****(relocated from Chapter 2E)**

**Notes:**
The following slides discuss the significant proposed revisions in the new Chapter 2F, which contains material that is being relocated from Chapters 2D and 2E.

## General Service signs now in separate Chapter

**Notes:**
A new chapter called “2F – General Service Signs” is being added.  This new chapter contains sections regarding general service signs, rest and scenic area signs, radio information signs, and carpooling signs that are being relocated from Chapters 2D and 2E in order to group similar sign types in the same area of the MUTCD.

##  New general service signs

** ****Revised  general service****  signs**

**Telecommunic. device for the deaf**

**Wireless internet**

**Notes:**
Also included are 2 new general service symbol signs (telecommunication device for the deaf [TDD], and Wireless Internet) and revised designs for the Information sign (currently a question mark symbol which is not well understood) and Truck Parking (replacement of word message with symbol).

## Interstate Oasis signing

**Notes:**
Information about a new program called Interstate Oasis signing is being added to describe signing for facilities that have been designated by the State within which they are located as having met the eligibility criteria of FHWA’s Interstate Oasis Policy.  Included within these provisions is a unique symbol that is being added for use on separate Interstate Oasis signs in conjunction with the word message.  A new option is being added for the use of the supplemental message INTERSTATE OASIS below a General Service sign if a business at the interchange has been designated as an Interstate Oasis facility. 

## “Dial” changed to “Call”

**Notes:**
The legend of the EMERGENCY DIAL 911 sign is being revised to use the word “CALL” rather than “DIAL” to be consistent with other signs and to reflect current terminology.

## Brake Check Area and          Chain-Up Area signs

**Notes:**
Brake Check Area signs are being added for use by States that provide areas for trucks and other vehicles to check their brakes in advance of the start of a long downhill grade.
Also, Chain Up Area signs are being added for use by States that provide off-road areas (on the shoulder or in a physically separated rest area type of roadway) for drivers to install and remove tire chains during winter weather conditions.
FHWA believes these types of areas are similar in some ways and could be considered motorist services and should be consistent in color and legend. 

## These signs are being changed from warning signs to general service signs

**Notes:**
Signs that are associated with Truck Escape Ramps are being relocated from Chapter 2C to Chapter 2F and their color is being changed from black-on-yellow to white-on-blue to clarify that these types of signs convey motorist service information (similar to brake check areas, chain up areas, etc.), rather than warnings. 

## Revisions toChapter 2G – Specific Service Signs(formerly Chapter 2F)

**Revisions to****Chapter 2G – ****Specific Service Signs****(formerly Chapter 2F)**

**Notes:**
The following slides discuss the significant revisions that are being made to the material in Chapter 2G, which was formerly Chapter 2F.

## 12 logos on two signs allowed for one service type at an interchange

**Notes:**
The requirement that a service type could only appear on one Specific Service sign is being changed to indicate that a service type is allowed to appear on up to two signs containing up to 12 logos for a given type of service.  The maximum of six logos per sign and the maximum of four Specific Service signs on an approach to an interchange are being retained.  Therefore, to display more than six logos for a single service, two signs would be required. These provisions reflect a recent Interim Approval.  A new recommendation is also being added indicating that when a service type is displayed on two signs, the signs for that service type should follow one another in succession. 

## Recommended minimum             letter heights for word-message  logo panels

**8 inch letters for freeways/expressways**
**6 inch letters for ramps and conventional roads**

**Notes:**
New guidance is included that the letter heights for word message logo panels should be a minimum of 8 inches for freeways and expressways and 6 inches for conventional roads and ramps  This change provides enhanced legibility of word-message logo panels for older drivers.

## Supplemental messages and new RV-accessible symbol allowed within logo sign panels

**Notes:**
New provisions are being added regarding the use and design of supplemental messages within the logo sign panel to incorporate messages that are helpful to road users, such as DIESEL and 24 HOURS.  The use of the supplemental message OASIS within the logo panel of a business that has been designated as an Interstate Oasis facility is also included, per the FHWA policy memorandum on Interstate Oasis signing. 
Also, a new “RV Friendly” symbol is being added that may be used by businesses that are designed with facilities to accommodate the on-site movement and parking of recreational vehicles. The language was developed based on the conditions listed in Interim Approval IA-8, dated September 6, 2005, as well as additional criteria, such as an alternate RV Friendly symbol design and placement, and the need for an engineering study to demonstrate that a U-turn can be made by RVs, if U-turns are needed to access the RV Friendly site desiring to be signed as such.

## Dual-logo sign panels for two businesses in a common facility

**Notes:**
Based on research in Texas, provisions are being added regarding the use of dual logo panels (two smaller logos on the same panel) on Specific Service signs when the two businesses are under the same roof, all available logo panels are already in use, and there is no room for additional logos. This is not intended as a way of providing more logos when the space is not available for additional business logos. Dual logo panels are being limited to two food businesses or one food and one gas business.  The recommended maximum number of dual logo panels used on any one Specific Service sign is two.

## Specific service trailblazer signs

**Notes:**
New provisions are being added regarding Specific Service trailblazer signs that are required along crossroads for facilities that have logo panels displayed along the main roadway and ramp, and that require additional vehicle maneuvers to reach. 

## NO Significant Revisions toChapter 2H – Tourist-Oriented Directional Signs(formerly Chapter 2G)

_**NO**_** Significant Revisions to****Chapter 2H – ****Tourist-Oriented Directional Signs****(formerly Chapter 2G)**

**Notes:**
There are NO significant proposed revisions to the material in Chapter 2H, which was formerly Chapter 2G.

## New Chapter 2I – General Information Signs

**New Chapter 2I – ****General Information Signs**

**Notes:**
The following slides discuss the significant proposed revisions in the new Chapter 2I, which contains information that is being relocated from Chapters 2D and 2E.

## New Chapter with sections relocated from                        Chapters 2D and 2E

**Reference location signs**
**Traffic signal speed sign**
**Other I-series general information signs**
**Memorial signing**
**Trail signs**
**Acknowledgement signs**

**Notes:**
A new chapter called “2I – General Information Signs” is being added.  This new chapter contains sections regarding reference location signs, traffic signal speed signs, general information signs, and miscellaneous information signs that are being relocated from Chapters 2D and 2E in order to group similar sign types in the same area of the MUTCD.

## Size of this sign is being increased from 12” x 18” to 24” x 36”

**Changeable message element allowed for varying progression speed**

**Notes:**
The SIGNALS SET FOR XX MPH sign is being increased in size so that it can be read when mounted overhead on a mast arm or signal span.
Also, a changeable message element for the numerals of the Traffic Signal Speed sign is allowed to be displayed if different system progression speeds are set for different times of the day, and a blank-out version of the Traffic Signal Speed sign may be used to display the message only during the times when the system is operated in coordinated mode.

## New Ferry Terminal sign                 for I-series 

**Notes:**
Within the I-series of General Information signs are various symbol signs for use in leading road users to certain types of transportation facilities. A new Ferry Terminal sign is being added to this series of signs.  The design is based on research by the Traffic Control Devices Pooled Fund Study.

## New provisions on the design and use of acknowledgement signs

**Notes:**
Based on a 2005 policy memo, new provisions are being added regarding the placement and design of acknowledgement signs that can be used as a way of recognizing a company, business, or volunteer group that provides a highway-related service. 

## Revisions toChapter 2J – Recreational and Cultural Area Interest Signs(formerly Chapter 2H)

**Revisions to****Chapter 2J – ****Recreational and Cultural Area Interest Signs****(formerly Chapter 2H)**

**Notes:**
The following slides discuss the significant proposed revisions to the material in Chapter 2J, which was formerly Chapter 2H.

## Updated and expanded set of recreational and cultural symbol signs

**Notes:**
The entire set of recreational and cultural interest area symbol signs are being replaced with a new updated and expanded set of signs, based on the National Park Service’s updated Uniguide Standards Manual, plus a few United States Forest Service standard symbol signs for activities not covered in the Uniguide standards. 

## Recreational and cultural interest area prohibitory signs

**Notes:**
To be consistent with National Park Service standards, the designs for recreational and cultural interest area prohibitory signs show the red diagonal slash being placed behind the symbol, rather than over it.  This is being done because the symbols on recreational and cultural interest area signs are much more detailed than those on standard highway signs and a slash placed in front might cover important aspects of the symbol. These recreational and cultural interest area symbol signs for prohibited activities and items are only to be used within recreational or cultural interest areas, and only when a standard regulatory sign for such a prohibition is not provided in Chapter 2B. 

## Revisions toChapter 2K – Emergency Management Signing(formerly Chapter 2I)

**Revisions to****Chapter 2K – ****Emergency Management Signing****(formerly Chapter 2I)**

**Notes:**
The following slides discuss the significant proposed revisions to the material in Chapter 2K, which was formerly Chapter 2I.

## Tsunami Evacuation Route                 sign

**Notes:**
A new Tsunami Evacuation Route sign is being added.  The design features the symbol currently being used in all Pacific coast states. 

## New option for fluorescent pink background when EM-6 or EM-7 signs are used in an incident situation

**or**

**Notes:**
A new option is being added that allows the use of a fluorescent pink background color when Emergency Aid Center or Shelter Direction signs are used in an incident situation, such as during the aftermath of a nuclear or biological attack. 

## Revisions toChapter 2L – Object Markers and Barricades(formerly Chapter 3C and Section 3F.01)

**Revisions to****Chapter 2L – ****Object Markers and Barricades****(formerly Chapter 3C and Section 3F.01)**

**Notes:**
The following slides discuss the significant proposed revisions to the material in Chapter 2L, which was formerly Chapter 3C for object markers.  Barricade provisions are being relocated from former Section 3F.01.

## Object markers and barricades are being relocated from Part 3 to new Chapter 2L

**Notes:**
The object marker provisions from Chapter 3C and the barricade provisions from Section 3F.01 are being relocated to Part 2 to form a new Chapter 2L.  Object markers and barricades are typically fabricated from retroreflective sheeting mounted on a substrate and installed on a post and thus are more like a sign than a marking, and most public agencies handle object markers and barricades as signs rather than markings.

## Option to use type 1 or type 3 object marker on nose of median island at intersection

**Notes:**
A new option is being added to clarify that Type 1 or Type 3 object markers may be installed on the nose of a median island at an intersection to provide additional emphasis.

## New Section on traffic gates

**Notes:**
A new Section 2L.06 is being added that gives provisions regarding the use of traffic gates for various purposes, including uses other than the most common use at highway-rail grade crossings.  All stripes used on gates, including those for railroad crossings, would be required to be vertical stripes rather than diagonal.  This will be discussed further in Part 8.

## New Chapter 2M – Changeable Message  Signs

**New Chapter 2M – ****Changeable Message  Signs**

**Notes:**
The following slides discuss the significant proposed revisions to the material on Changeable Message Signs that formerly was scattered throughout the MUTCD, but is now being consolidated in a new Chapter 2M.

## Provisions forChangeable Message Signs

**- Legend Height****- Color****- Phases per Cycle****- Display Time**

**Notes:**
Information from existing Sections 2A.07 and 2E.21 as well as additional new information is being relocated or added to form a new Chapter 2M to consolidate all information about changeable message signs into one location and to incorporate the results of extensive research on changeable message sign legibility, messaging, and operations that has been conducted over a period of many years. Additional information on portable changeable message signs will be included in Part 6 to address their specific display capabilities.
