A new free app is available to encourage users to have a plan to get home safely if they're impaired by alcohol or drugs.

The "Have A Plan" app includes features like an ability to create a list of designated drivers based on a user's own contact list.  The app can also find a nearby taxi using GPS, an alcohol impairment estimator, a set of various motor skills tests to assess impairment level, as well as a "Report DWI" button that connects users to the local 911 service.  In addition, the app offers a list of DWI facts and myths, and access to a variety of social media sites sponsored by STOP-DWI, who developed the app.

"Have A Plan' is free and available for iPhone, Android and Windows smartphones.
