Talking urinals have been introduced in Michigan to discourage drinkers from taking to the road during celebrations on July 4.

The motion sensored devices feature a woman's voice which tells users to take a cab if they have had a lot to drink. It also reminds men to wash their hands.

Melody Kindraka from the Michigan State Police Office of Highway Safety Planning explains: "Men are three times more likely to drive drunk than women, so by going into bathrooms we can target men specifically with the urinal communicator, and it helps to generate a conversation.

"A guy can go in there and hear a woman's voice talking to him and maybe go back and talk to his buddies about, 'hey, let's find a sober ride home'."

Bay, Ottawa and Delta counties also are also planning to install the devices, as part of a nation-wide push to prevent drink driving during Wednesday's celebrations.
