The proposed SAE Standard establishes the performance specifications for the Directed–breath, Contactless, Zero Tolerance alcohol detection sensor for use by fleets and as a franchised dealer installed accessory device where some minor inconvenience of the operator may be tolerated. Specifications for accuracy and precision of the measurement, speed of measurement, performance in differing environmental operating conditions, long–term reliability, system maintenance, and user acceptance are established including acceptance criteria.
The Performance Specifications and acceptance criteria established herein are NOT applicable, nor acceptable, for an alcohol detection sensor that is to be widely deployed in privately operated vehicles (“POV”) which requires passive sensing.
Rationale: In the United States, in 2016, 10,497 people died in alcohol–impaired driving crashes, accounting for 28% of all traffic–related deaths in the United States. Also, in 2016, more than 1 million drivers were arrested for driving under the influence (“DUI”) of alcohol or narcotics. That is approximately one percent of the 111 million self–reported episodes of alcohol–impaired driving among U.S. adults each year. About twenty to twenty–eight percent (20%~28%) of first–time DUI offenders will repeat the offense, and recidivists are sixty–two percent (62%) more likely to be involved in a fatal crash.
Since 2008, the Automotive Coalition for Traffic Safety, Inc. (“ACTS”) has been working with the U.S. Department of Transportation's National Highway Traffic Safety Administration (“NHTSA”) as part of a public–private partnership to develop vehicle–integrated technologies to prevent drunk driving – what has become known as the Driver Alcohol Detection System for Safety (“DADSS”) Program. The Program is dedicated to advancing the state of alcohol detection systems for motor vehicles. Its explicit mission is to, “explore the feasibility, the potential benefits of, and the public policy challenges associated with a more widespread use of non–invasive technology to prevent alcohol-impaired driving.”
Deployment of DADSS technologies is contemplated, initially, in motor vehicle fleets, and possibly as a franchised dealer–installed accessory device, followed by widespread deployment in all motor vehicles as standard equipment. The DADSS technology, therefore, must be accurate, precise, repeatable and reproducible over the 20–year life of a vehicle for the variety of people (ethnicity, gender, medical condition, etc.) from which the measurement is to be made who will use that vehicle over its lifetime.
