The bill S.146, introduced by Senators White and Harrison, mandates that employers with 50 or more employees in Vermont must establish a Transportation Demand Management (TDM) plan aimed at reducing vehicle miles traveled. The new chapter added to the Vermont Statutes, Chapter 23, outlines definitions related to TDM, including what constitutes an employee, employer, and transportation management association. The bill specifies that employers must design, adopt, and implement a TDM plan that includes various measures such as telecommuting, incentives for carpooling, and staggered work shifts.

Additionally, the bill requires employers to consult resources such as the Agency of Transportation's TDM Guidance document and local transportation management associations when developing their plans. The Secretary of Transportation is authorized to adopt rules to establish requirements for the content of these plans. The act will take effect upon passage, with a compliance deadline set for January 1, 2026, for the affected employers to implement their TDM plans.
