All Regional Transportation District services will be fare-free during the month of August. They're calling the program "Zero Fare for Better Air."
The goal is to reduce ground-level ozone by increasing the use of public transit.
The effort is made possible by Colorado Senate Bill 22-180, the ozone season transit grant program, in partnership with the Colorado Energy Office.
RTD said Aug. 1 to Aug. 31 is Colorado’s high ozone season.
Colorado Gov. Jared Polis signed the bill earlier this month to funnel money toward the state’s transit agencies, allowing them to offer fare-free days during the summer.
