What the Transportation Lobbying Data Shows
Under Senate Lobbying Disclosure Act code TRA, 342 organizations reported federal lobbying activity on Transportation across the 2023-2024 reporting period, with combined expenditures of $10.4M. That volume of filings places Transportation among the issues where corporate, trade-association, and advocacy lobbying is actively shaping the legislative and regulatory agenda, with each registrant required to disclose specific bills, agencies contacted, and in-house lobbyists engaged.
PACCAR INC leads all filers on this issue with $720K in tracked lobbying expenditures, and the top 10 reporting organizations — including PACCAR INC, AMERICAN AIRLINES INC., TRANSPORTATION INTERMEDIARIES ASSOCIATION — typically account for a disproportionate share of total outlays, a concentration pattern that repeats across most LDA issue codes. Each of these organizations files quarterly LD-2 disclosures naming the lobbyists deployed and the chambers of Congress or executive agencies contacted.
The 342 filers tracked here represent a structured picture of who is paying to be heard on Transportation — useful context when evaluating hearings, committee markups, and rulemaking on related topics. Because LDA filings are a public-record trailing indicator, spending in the 2023-2024 window reflects priorities that will continue to ripple through the 118th and 119th Congresses before any policy outcomes register in the data.
