SANDAG encourages people in the San Diego region to support California Clean Air Day. Pledge to get moving for clean air on Wednesday, October 1, by walking, biking, carpooling, or riding transit for free, thanks to MTS and NCTD. San Diego commuters travel more miles annually than the state average, making Clean Air Day the perfect opportunity to help clean the air.    
 
This year, eligible residents within the San Diego region will be automatically entered for the chance to win a folding e-bike, powered by Rad Power Bikes. When you pledge, make sure to check the box to receive communications from trusted partners in order to be notified.! Rad Power Bikes will coordinate prize redemption with the winner. Terms and conditions apply.
