Drunk driving kills and injuries hundreds of thousands of people every year across the world, tragedies that could so easily be avoided if people realized they were impaired and opted out of taking the risky trip home. But unfortunately alcohol also has the effect of making us over-confident in our abilities, and so these tragic accidents keep happening just because we think we’re fine when we aren’t.

Now a strange but fruitful partnership between a Singapore ad agency and a nightclub has come up with a technology solution which looks as though it could really help reduce the problem. The Pee Analyzer is a system which integrates an alcohol sensor with an RFID chip reader and a valet parking smartcard to deliver an effective deterrent to inebriated drivers every time they visit the men’s room.

The sensor sits in the bottom of the urinal, and can detect alcohol levels in urine. If the sensor detects too much, then a message is displayed on a screen in front of the urinal advising the person to call a cab or use the club’s drive home service. Simple and effective. But it doesn’t stop there.

The RFID smartcard is also the valet parking token, and when presented to the concierge to retrieve the car, it is scanned and if the excess alcohol results are detected a warning again is displayed and the driver is advised to leave their car in the lot and get home another way.

Testing was recently done at Zouk, one of Singapore’s top nightclubs, and in just two weeks detected 573 at risk drivers, of which a staggering 342 opted to leave the car and take an alternative way home. That’s over 300 potential disasters averted in just two weeks at a single club. Think what this could mean to road safety if it was rolled out everywhere.

Watch the video below for more details. Oh and no, we don’t know whether they’ve come up with a version for female drivers yet. Very cool technology indeed.
