With Austin traffic expected to rear its ugly head even more intensely on the first day of South by Southwest, Lyft is hoping you'll join them for a "Ditch Day" by leaving the car at home and taking a shared ride.

Lyft teamed up with Capital Metro, Movability and Downtown Austin Alliance to create Ditch Day on March 8 in anticipation of increased people and traffic in Austin. Lyft and Capital Metro are offering discounted and free rides, respectively, to get you to hop in.

The companies also want to show commuters that they can reduce stress and reduce carbon emissions by taking a shared ride on any day.

“Austinites don’t have to wait for new infrastructure to begin addressing transportation issues in our city,”  Executive Director of Movability Lisa Kay Pfannenstiel said in a Lyft press release. “Ditch Day encourages Austinites to rethink transportation habits, enabling us to choose options that save money, increase productivity and reduce stress while on the road.”

To participate in the Lyft promo, enter DITCHDAY in the ‘Promos’ section of the Lyft app to get 25 percent off of two Lyft Shared rides on March 8. Capital Metro is offering free passes for the day. Registration for day passes closes March 6 at 11:59 p.m.

Another perk: If you post on social media on March 8 with the hashtag #DitchDayATX, you could potentially win $100 in Lyft credit.
