All day

Get ready for Free Ride Day on Wednesday, October 1! All MTS Trolleys and buses, as well as the NCTD COASTER, SPRINTER and BREEZE, will be free to ride all day (no payment needed).

In a time when MTS is seeing ridership growth (81+ million trips!), Free Ride Day has been the highest ridership day for us the last few years! Did you know that idling your vehicle for just 10 minutes releases 1 pound of carbon dioxide into the air? Free Ride Day is a great chance to try a new commute, explore more with family or friends, or just give your wallet a break. How many people will get on board this year?
