Switzerland's 'drive-in sex boxes' or guarded prostitution site has been highly successful, just two months after their installation in Zurich.
Michael Herzig, the director of social services for sex workers, said that the prostitution site, which is open daily from 7:00 pm to 5:00 am, is working, the New York Daily News reported.
The 'sex boxes', which are simple wooden structures, were constructed on the outskirts of the Swiss city in hopes of getting prostitution out of city and to make the business safer for people of ill repute.
The site is staffed around the clock with security guards to ensure the safety of the sex workers.
