The SmartCommute Challenge is an annual non-profit public service campaign that works to reduce traffic congestion and improve air quality in the Triangle.

From April 15 through May 30, any employee or college student who commutes to work or campus in Wake, Durham, or Orange County can participate. To enter the Challenge, make your online pledge that at least once before May 30 you will carpool, vanpool, bike or walk, ride the bus, or telework (work from home).

Everyone who takes the Challenge will be entered into a drawing to win one of several prizes, including a free vacation for two!

You can take the pledge [2] individually, or get your company to sign on [3] collectively!
