The U.S. Department of Transportation administers SBIR Phase II as the principal R&D stage of its Small Business Innovation Research program. Phase II follows a DOT Phase I award and supports continued transportation R&D with commercialization potential.

DOT states that Phase II is the principal research or R&D effort, with an approximately two-year period of performance and a dollar value up to USD 1,500,000. DOT accepts Phase II proposals only from firms that previously received a DOT Phase I award, and awards are based on Phase I results, technical merit, commercialization potential, and follow-on funding commitment.

This row is modeled as between cycles because the captured current-cycle page announces the FY26 Phase I solicitation, while the program page describes the standing Phase II path without a currently open Phase II deadline. Companies should use this page to understand the Phase II opportunity, but must wait for DOT Phase II instructions after receiving a Phase I award.
