October 1, 2025 is California Clean Air Day – a day dedicated to reducing pollution, improving air quality, and creating a healthier future. One of the best ways to make an impact is to leave the car at home and ride public transit.
Transit keeps thousands of cars off the road every day, cutting greenhouse gas emissions, easing traffic congestion, and helping communities breathe cleaner air.
This year, many California transit agencies are making it even easier to ride – by offering free rides all day on October 1.
