Revisions to the 2011 MdMUTCD

• Revision to Table of Content TC-28, Section 6E.04 Automated Flagger Assistance Devices and Section 6E.06 Red/Yellow Lens Automated Flagger Assistance Devices has been made to allow the use of Red and Yellow Lens Automated Flagger Assistance Devices (AFAD). (Approved by FHWA on March 13, 2023)

• Revision to Section 6C.01 Temporary Traffic Control Plans has been made to reflect the current Maryland law for speed limit reduction in work zones. The original 2011 MdMUTCD standard prohibiting the speed reduction above 10 mph had been established when the maximum speed limit allowed in the State of Maryland was 65 mph. Maryland law, effective October 1, 2015, allows posted speed limits up to 70 mph on interstate highways and expressways. (Approved by FHWA on January 12, 2023)

• Revision to Table 2B-1 and Figure 2B-10 from Section 2B has been made to allow the use of DO NOT DRIVE ON SHOULDER (R4-17) sign. (Approved by FHWA on December 12, 2022)

• Revision to Section 2B.13 Speed Limit Signs (R2-1) has been made to:
  • Emphasize and clarify that other factors previously listed as optional, in addition to the 85th percentile speed, have a role in setting speed limits;
  • Limit use of the 85th percentile speed to freeways, expressways, and rural highways as a factor that should be considered; and
  • Incorporate the Safe System Approach by USDOT to strengthen protection for vulnerable road users. (Approved by FHWA on March 23, 2022)
• Revision to Section 3B.18 Crosswalk Markings, and Section 7C.02 Crosswalk Markings has been made to reflect the updated standard by MDOT SHA, effective March 5, 2019, for enhanced visibility crosswalk markings. The new standard utilizes longitudinal lines without transverse lines, known as the “longitudinal bar” or “continental” crosswalk. (Approved by FHWA on March 23, 2022)​
