PRESS RELEASEAmbitious Drunk Driving Prevention Research Program Moves

Forward

Drivable Test Vehicle Expected in Two Years

The national research effort to develop publicly-acceptable technology that will preventthe illegal operation of a vehicle by a drunk driver (0.08 or above blood alcohol content)is entering a new phase in which it will move out of the laboratory and onto the road witha drivable test vehicle expected to be ready in two years.

The Driver Alcohol Detection System for Safety (DADSS) research program, whichbegan in 2008, is a five-year, $10 million cooperative research effort of the NationalHighway Traffic Safety Administration (NHTSA) and the Automotive Coalition for TrafficSafety (ACTS), representing the nation’s leading automakers.

“What we’re doing is developing technology that won’t hassle sober drivers; will requirevirtually no maintenance or upkeep; and will have such precision that it only stops adriver when their blood alcohol content is at or exceeds 0.08 blood alcohol content(BAC) – which is the legal limit that policymakers have set for drunk driving in everystate,” said Rob Strassburger, Vice President Safety & Harmonization of the Alliance ofAutomobile Manufacturers. “This will be lifesaving technology.”

Autoliv Development AB of Sweden and Takata-TruTouch of Auburn Hills, Michigan andAlbuquerque, N.M., are both involved in the next research phase. Each company hasbeen awarded $2.25 million after successfully demonstrating during the proof-of-

concept phase that they have the potential for ultimately meeting stringent performancecriteria established for DADSS.

AMBITIOUS DRUNK DRIVING PREVENTION RESEARCH PROGRAM MOVES FORWARD PAGE 2

FOR RELEASE 9 A.M. EDT, TUES., NOVEMBER 1, 2011 MORE

Installation of the prototype DADSS systems into a research vehicle continues thedevelopment of these technologies for subsequent voluntary installation in productionvehicles in the next 8 to 10 years.

Autoliv is developing a breath-based testing device for BAC detection, while Takata-TruTouch is working on a touch-based approach. (See descriptions below.)

“While the nation has made great strides in reducing drunk driving over the years, itcontinues to be one of the leading causes of death and injury on America's roads,claiming a life every 48 minutes. Advanced alcohol-detection technologies are apromising new tool to prevent drunk drivers and repeat offenders from getting behindthe wheel,” said U.S. Transportation Secretary Ray LaHood, who visited the DADSSlaboratory in the Boston area with NHTSA Administrator David Strickland in January.

“As a public health and safety agency we’re deeply concerned about drunk drivers andthe safety risk they impose on all motorists,” said Administrator Strickland. “No matterwhat the future holds for advanced alcohol-detection technologies, one thing remainsclear; no technology can, or should, ever replace a driver’s personal responsibility not todrive drunk.”

Mothers Against Drunk Driving (MADD) National President Jan Withers, whose 15-year-old daughter, Alisa Joy, was killed by a drunk driver, noted that development ofadvanced alcohol detection technology is a major element of MADD's Campaign to Eliminate Drunk Driving , which is marking its fifth anniversary in November. “There hasbeen great progress in reducing drunk driving deaths and injuries over the past 30years,” Withers stated, “but there were still nearly 11,000 such fatalities in 2009, nearlyone-third of the traffic toll. DADSS has the potential to prevent an estimated 8,000drunk driving deaths a year.”

Opinion research indicates that the public is ready for such a device. Research showsthat two‐thirds of those surveyed considered the use of advanced technology to keepdrunk drivers off the roads to be a “good” or “very good” idea.

Description of DADSS Technologies

The DADSS Program has identified two technological approaches as havingconsiderable promise in measuring driver BAC non-invasively: (1) Tissue Spectrometry,a touch-based approach allowing assessment of alcohol in the driver’s skin, and (2)Distant Spectrometry, a breath-based approach that will allow assessment of alcohol

concentration in the driver’s exhaled breath. Each technological approach is describedbriefly below.

Touch-based Approach

In the touch-based approach, measurement begins by shining an infrared light on theuser’s skin (similar to a low power flashlight). A portion of the light scatters severalmillimeters through the driver’s skin before returning back to the skin’s surface where itis collected by the optical touch pad. This light contains information on the skin’s uniquechemical properties which can be analyzed to determine the driver’s alcoholconcentration.

Breath-based Approach

The breath-based approach makes it possible to perform a contact free, quick,unobtrusive measurement of the driver’s breath alcohol by using the concentrations ofcarbon dioxide as a measure of dilution of the driver’s exhaled breath. Multiple sensorsplaced in the vehicle cabin will allow the system to ensure that the breath sample isfrom the driver and not other passengers.
