2402 Delaware Manual on Uniform Traffic Control Devices, Parts 2, 3, and 6

Under Title 17 of the Delaware Code, Sections 134 and 141, as well as 21 Delaware Code Chapter 41, the Delaware Department of Transportation (DelDOT) adopted a Delaware version of the Federal Manual on Uniform Traffic Control Devices (MUTCD). The Department then drafted changes to Parts 2, 3, and 6 of the Federal MUTCD, and published a Notice seeking public comment on these changes in the March l, 2009 edition of the Delaware Register. Other portions of the MUTCD have already been drafted and adopted.

Summary of the Evidence and Information Submitted

No comments were received regarding these proposed changes to the MUTCD. Since the initial publication for comment, however, the Department made a small change in its draft of the amendments to Part 3. This is related to Figure 3B-16A. The change will be to note 2 in the figure. The revised note 2 should read "Double Yellow Pavement Markings should be placed in the median if W ? 30m (50 ft)." This change makes the recommendation for double yellow centerline markings less restrictive. The Department considers this change to be non-substantive in nature, and thus no new comment period is required.

Findings of Fact

Based on the record in this docket, I make the following findings of fact:

1. The proposed amendments to Parts 2, 3, and 6 of the Delaware version of the MUTCD are useful and proper, as amended pursuant to the comment period process required under the Administrative Procedures Act.

2. The adoption of these proposed changes to the MUTCD for Delaware is in the best interests of the State of Delaware.

Decision and Effective Date

Based on the provisions of Delaware law and the record in this docket, I hereby adopt the amended Parts 2, 3, and 6 of the MUTCD, as set forth in the version attached hereto, to be effective on May 21, 2010.

IT IS SO ORDERED this 22d day of April, 2009.
