Technology Targets Drunk Drivers
Scientists say several high-tech toxicology tools are being developed to combat drunk driving, many of which were unveiled at an exhibition sponsored by MADD (Mothers Against Drunk Driving).
One of the devices displayed was an “ignition interlock,” which prevents a vehicle from starting if the breath of person blown into a tube shows a blood alcohol level above a certain point.
Researcher Paul Marques at the Pacific Institute for Research and Evaluation (PIRE) says interlock devices have been known for 20 years, but that the technology is “underutilized.” One of the obstacles is that courts seldom mandate interlocks. Even though 1.4 million DUI arrests occur annually, only 100,000 interlocks are being used.
The device helps reduce repeat offenses by 65%. Other emerging technologies include trans-dermal alcohol detectors such as SCRAM (Secure Continuous Remote Alcohol Monitor), which is worn like an ankle bracelet and provides periodic wireless updates to law enforcement.
There are also sensors that analyze the air around a person’s face and which can be hidden inside a flashlight.
Another device featuring near-infrared spectroscopy can evaluate blood alcohol composition under the skin; the technology is still under development.
“Technology can help [alleviate the problem], but we can’t do it without a human program,” observes Marques.
