In celebration of Earth Day on Monday, April 22, Metro is offering free rides on buses, trains, and bike-share bikes. The free rides begin at 4 a.m. on April 22 and continue until 3 a.m. on Tuesday, April 23.

You won’t need to use your TAP card. Station gates will be open to allow you to pass through.

The idea behind the freebie rides is to encourage people to take transit and help reduce air pollution and greenhouse gas emissions in L.A. County.

Taking a bus or train instead of driving alone is a good way to reduce the greenhouse gas emissions your activities produce. It’s also a high-impact way to reduce your household’s greenhouse gases.

As part of this year’s free rides, Metro will also be handing out stickers reminding riders of their good deed and putting posters up across the system.

Besides Metro, other transit agencies also offering free rides on Earth Day.

Metrolink is offering commuter rail service across Southern California.

Metro Bike Share will allow you to unlock free 30-minute bike rides with the promo code 4222019. Usage fees of $1.75 per each 30 minutes thereafter apply. The code can be used multiple times throughout the day. Valid at any Smart or Classic Metro Bike Share station. Not valid online.
