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 bill outlines definitions for key terms such as "employee," "employer," "transportation demand management," and "transportation management association." It requires these employers to design, adopt, and implement a TDM plan that includes various measures, such as telecommuting and incentives for carpooling or using public transit. Employers are encouraged to consult resources like the Agency of Transportation's TDM Guidance document and local transportation management associations when developing their plans.

Additionally, the bill empowers the Secretary of Transportation to adopt rules to establish requirements for the content of TDM plans. The act is set to take effect upon passage, with a compliance deadline for employers to implement their TDM plans by January 1, 2026. This legislation aims to promote sustainable transportation practices and reduce traffic congestion in Vermont.
