{"data":{"id":"us/49-cfr-33.31","jurisdiction":"us","citation":"49 CFR 33.31","heading":"Priority ratings.","body":"(a) Levels of priority. (1) There are two levels of priority established by the Transportation Priorities and Allocations System regulations, identified by the rating symbols “DO” and “DX”.\n(2) All DO-rated orders have equal priority with each other and take precedence over unrated orders. All DX-rated orders have equal priority with each other and take precedence over DO-rated orders and unrated orders. (For resolution of conflicts among rated orders of equal priority, see § 33.34(c).)\n(3) In addition, a Directive regarding priority treatment for a given item issued by the resource agency with priorities jurisdiction for that item takes precedence over any DX-rated order, DO-rated order, or unrated order, as stipulated in the Directive. (For a full discussion of Directives, see § 33.62.)\n(b) Program identification symbols. Program identification symbols indicate which approved program is being supported by a rated order. DOT will use the letter “T” followed by a number for all transportation-related approved programs. Programs may be approved under the procedures of Executive Order 13603 at any time. Program identification symbols, in themselves, do not connote any priority.\n(c) Priority ratings. A priority rating consists of the rating symbol—DO and DX—and the program identification symbol, such as DO-T1 or DX-T1 for a priority rating under TPAS.","path":["Title 49—Transportation","Subtitle A—Office of the Secretary of Transportation","PART 33—TRANSPORTATION PRIORITIES AND ALLOCATION SYSTEM","Subpart C—Placement of Rated Orders"],"source_url":"https://www.ecfr.gov/api/versioner/v1/full/2026-08-25/title-49.xml","current_through":"2026-08-25","vintage":"","retrieved_at":"2026-08-27T02:26:34Z","sha256":"5f6e0ba2818da0e02f6c8daf9f204c6c8693b26b3cb597f1574f2e21fae44d70","source_id":"us-cfr","stale":true,"prev":"us/49-cfr-33.30","next":"us/49-cfr-33.32"},"notice":"GroundRules: Original legal text.
