Small businesses that once qualified automatically for a share of federal highway, transit and airport contracting dollars because their owners were Black, Hispanic, Native American, Asian-Pacific American, Subcontinent Asian American or women no longer get that automatic boost. As of today, the U.S. Department of Transportation has finalized a rule requiring every applicant to its Disadvantaged Business Enterprise (DBE) and Airport Concession Disadvantaged Business Enterprise (ACDBE) programs to prove, in an individualized written narrative, that they are actually socially and economically disadvantaged before they can count toward a recipient's contracting goals.
The final rule, published in the Federal Register on Sept. 25, 2026 under Docket No. DOT-OST-2025-0897 and RIN 2105-AF33, takes effect the same day it was published. It amends the DBE and ACDBE program regulations at 49 CFR Parts 23 and 26, and it largely locks in place the interim final rule (IFR) DOT issued on Oct. 3, 2025, which first eliminated the statutory presumptions of disadvantage that Congress had directed the department to apply to those groups.
DOT's rationale traces directly to two executive orders and a Justice Department directive. The department concluded that the race- and sex-based presumptions could no longer stand in light of Executive Orders 14151 and 14173 and the Attorney General's March 21, 2025 memorandum ordering agencies to eliminate unlawful diversity, equity and inclusion programs. Rather than dropping group-based eligibility screening altogether, DOT replaced it with a requirement that every DBE and ACDBE applicant submit a personal narrative demonstrating their own disadvantage, regardless of race or sex.
Why DOT Says the Old Presumptions Were Unconstitutional
DOT's position is that a presumption of disadvantage tied to a person's race or sex cannot survive current constitutional scrutiny, and that the only way to keep directing highway, transit and airport contracting dollars toward genuinely disadvantaged small businesses is to evaluate each applicant on their own evidence. The department frames the shift as a completion of work it began with last year's interim rule, not a new direction.
"This action completes the transition to a system of individualized determinations of social and economic disadvantage to ensure program constitutional compliance and addresses administrative challenges identified by stakeholders during the public comment period," DOT wrote in the final rule's preamble.
The DBE program itself is not new — it has operated since 1983 and was most recently reauthorized under the Infrastructure Investment and Jobs Act (Pub. L. 117-58), requiring any recipient of DOT highway, transit or airport funding to set participation goals for small disadvantaged-business contractors. The ACDBE program imposes similar requirements on airport concessionaires under 49 U.S.C. 47107(e). What DOT changed is not whether those goals exist, but how a firm proves it belongs inside them.
What Changed Between the Interim Rule and Today's Final Rule
The final rule is DOT's response to 637 public comments filed against the October 2025 interim rule, and the department was explicit that it is not reopening the overall framework — the individualized-narrative requirement stands. But several comments raised confusion about how far the new standard reached, and DOT used the final rule to narrow that confusion rather than the policy itself.
The most significant clarification addresses a reading of the interim rule that alarmed commenters: that applicants would be barred from mentioning their own race or sex at all when describing disadvantage. DOT rejected that interpretation outright, confirming that applicants may describe their own experiences of race- or sex-based discrimination as part of an individualized showing, so long as the showing rests on personal evidence rather than group membership alone. The department also swapped terminology it judged legally cleaner: "systemic barriers" becomes "social barriers" throughout the regulatory text, and language describing "similarly situated" comparisons was replaced. DOT additionally set definitive deadlines for reevaluating a firm's disadvantaged status once certified, and streamlined the procedures a firm must follow to get certification recognized across state lines.
"The Department amended the definition to reflect the adoption of a constitutionally neutral process based on individualized evidence of actual social and economic disadvantage," DOT said in its response to comments accompanying the final rule.
How the DBE and ACDBE Certification Process Now Works
Under the final rule, a firm seeking DBE or ACDBE certification can no longer point to its owner's membership in one of the previously listed groups and receive a rebuttable presumption of disadvantage. Instead, the applicant's personal narrative has to stand on its own — describing specific circumstances, whether tied to race, sex, or other factors, that produced actual social and economic disadvantage for that individual. Certifying agencies then evaluate the narrative directly rather than checking it against a statutory list.
That individualized review sits alongside the economic thresholds the DBE and ACDBE programs already applied, and DOT's clarifications on reevaluation deadlines mean certified firms now know on a fixed timetable when their status will be revisited rather than facing certification reviews on an ad hoc basis. The interstate streamlining addressed a separate complaint from the comment period: firms operating across state lines had faced duplicative certification reviews from each state's Unified Certification Program, and the final rule narrows what those programs can re-litigate once a firm is certified elsewhere.
What It Means for Contractors
For firms currently certified as DBEs or ACDBEs, the practical question is whether their existing file already contains an individualized narrative or relies on the old group-based presumption; DOT's reevaluation deadlines will force that question for every certified firm on a set schedule rather than leaving it open-ended. For firms applying for certification for the first time, the bar is now uniform regardless of the owner's race or sex: a specific, evidence-based account of disadvantage, not membership in a listed group.
Prime contractors and DOT-funded recipients — state DOTs, transit agencies, airport authorities — also have to adjust their own compliance processes, since the goal-setting and counting mechanics underneath the DBE and ACDBE programs have not changed even though the certification standard feeding into them has. Firms and recipients now have a final rule to build compliance around instead of an interim one that carried more legal uncertainty, and DOT's clarification that applicants can still describe race- or sex-based discrimination in their own words removes one of the sharpest points of confusion the interim rule generated.
