Welcome to the Discovery Hub:

The Driver Alcohol Detection System for Safety (DADSS)™ Program:

  • First–of–its–kind, vehicle–integrated, alcohol detection technology

  • Passively detects a driver's blood alcohol concentration (BAC)

  • Prevents the car from moving if the driver’s BAC is at or above the legal limit of 0.08%

  • Technology must meet rigorous performance standards before it is installed in cars and trucks  

  • Offered to vehicle owners as a voluntary safety option, like other driver–assist systems such as automatic emergency braking or lane departure warning

Key Partners in the DADSS Program:


  • The Automotive Coalition for Traffic Safety (ACTS), a Virginia nonprofit funded by the world's leading automakers;

  • The U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA); and

  • The Virginia Department of Motor Vehicle's Highway Safety Office

  • The DADSS Program is one of the most important government and private sector partnerships in recent years.  Public-private partnerships like DADSS have led to innovations that enhance our everyday lives, such as the internet, GPS, and microchip.


The DADSS Driven to Protect™ Discovery Hub:

  • Allows you to learn about the dangers of alcohol–impaired driving and the innovative technology that Virginia is helping to develop to make its roads and highways safer

  • Learning modules to help you explore:

    • How alcohol is absorbed, processed and eliminated by the human body;

    • How alcohol impairs your ability to safely operate a motor vehicle;

    • Obtain actionable information to help you avoid the dangers associated with drunk driving;

    • Learn how the novel DADSS technologies that are currently under development and testing, can protect you and other motorists on the road in the future.

  • Science, Technology, Engineering & Math – STEM – modules that help students learn about the science and engineering behind the technology
