While many communities are committed to preventing and stopping drunk driving, it\u2019s simply not possible for local law enforcement to spot every impaired driver. But jurisdictions could soon get some high-tech help from&#160;lasers.<\/p>\n<p>Researchers in Poland recently used a \u201cstand-off detection\u201d system to measure moving cars for the presence of alcohol vapors. The system\u2019s laser goes through a car\u2019s windows to a sensor on the other side of the road and measures the air within the vehicle. Specifically, the device looks for the type of vapor emitted from the lungs when people&#160;drink.<\/p>\n<p>The idea is that when alcohol is detected in the car, the device can capture a picture of the car\u2019s license plate and forward that information to a law enforcement officer down the road.

Things like air conditioning and solar screens on windows can also interfere with the&#160;results.<\/p>\n<p>Is this promising new research? Or just a problematic violation of the rights of designated drivers\u2014or those who drink but are passengers? What about applying this at roadside sobriety checkpoints to triage cars where alcohol is present for further&#160;investigation?<\/p>\n<script src=\"\/\/fast.wistia.com\/embed\/medias\/ojajw15ar7.jsonp\" async><\/script><script src=\"\/\/fast.wistia.com\/assets\/external\/E-v1.js\" async><\/script><span class=\"wistia_embed wistia_async_ojajw15ar7 popover=true popoverContent=link\" style=\"display:inline\"><a href=\"#\"><img decoding=\"async\" src=\"https:\/\/www.scramsystems.com\/blog\/wp-content\/uploads\/scram-cam-product.jpg\"><\/a><\/span>\n","protected":false},"excerpt":{"rendered":"<p>Studies show that first-time DUI offenders drive drunk an average of 80 times before getting caught.
