Who buys at DOT
The FAA buys air traffic control systems and services directly, while most highway and transit money flows as grants to states, cities and transit agencies, which then run their own procurements.
- Federal Aviation Administration (FAA)
- Federal Highway Administration (FHWA)
- Federal Transit Administration (FTA)
- Federal Railroad Administration (FRA)
- National Highway Traffic Safety Administration (NHTSA)
How to start selling to DOT
- Register in SAM.gov. Every federal contractor needs an active SAM registration and Unique Entity ID; see our SAM registration guide.
- Check your NAICS codes and size. Each solicitation is assigned one NAICS code, and its size standard decides whether you can compete as a small business; see SBA size standards and the top NAICS codes for government contracts.
- Read the forecast. DOT's procurement forecast lists contracts planned for the coming year, often before they reach SAM.gov.
- Meet the small business office. DOT's Office of Small and Disadvantaged Business Utilization (or its equivalent) can explain how the agency buys and connect you with program offices.
- Consider contract vehicles. Many agency buys go through GSA's Multiple Award Schedule and other governmentwide or agency contracts rather than open competition.
- Find the program owner. Contracting officers run the process, but program offices decide what they need; reaching them before a solicitation is released is where deals are shaped.
Budget and funding timing
- Fiscal year. The federal fiscal year runs Oct. 1 to Sept. 30; see our government fiscal year calendar.
- Fiscal 2027 funding. DOT is operating under a continuing resolution through Dec. 11, 2026, which generally bars new starts; follow it in our FY 2027 appropriations tracker.
- Year-end buying. Agencies obligate a large share of contract dollars in the final quarter of the fiscal year, July through September.
