The Madison County Sheriff's Office is announcing the launch of a free mobile phone app that encourages people to have a plan to get home safely if they've had too much to drink.

The "Have A Plan" app operates on iPhone, Windows and Android platforms.

It includes features like the ability to preload a list of designated drivers, find a taxi via GPS and an alcohol impairment estimator.

The app was developed by STOP-DWI New York and Staples Marketing under a grant from the Governor's Traffic Safety Committee.
