The oldest profession in the world is getting a modern makeover.
Zurich is opening up its first sex drive-in -- also called "sex boxes"-- later this month in an effort to keep tabs on its sex workers.
Partially enclosed stalls that resemble those at self-service car washes are equipped with decorative lights -- for ambiance -- and alarms, so prostitutes can contact police quickly if they are in danger.
Patrons drive in through a marked route where up to 40 prostitutes will be stationed, according to The Local, Switzerland's English-language news site. Once a rate is negotiated, they will drive into one of the stalls to have sex.
Voters approved the so-called "sex box" business model in March 2012 and the site cost $2.2 million to build. It will officially open on Aug. 26.
Prostitution is legal in Switzerland and the sex stalls are the country's latest effort in ensuring the safety of prostitutes while fighting the underground sex trade. Its remote location in an industrial zone also satisfies residents who grew tired of sex workers plying their trade in the streets, according to The Local.
