Discovery Hub



Welcome to the Discovery Hub. Here, you can learn about the dangers of alcohol–impaired driving and the innovative technologies currently in development to make our roads and highways safer.

Driver Alcohol Detection System For Safety (DADSS) Program


DADSS is a first-of-its-kind, vehicle–integrated, alcohol detection technology. By passively detecting a driver's blood alcohol concentration (BAC), it prevents a car from moving while the driver’s BAC is at or above the legal limit of 0.08%.

This technology must meet rigorous performance standards before it can be installed in cars or trucks. When ready, it will be offered to vehicle owners as a voluntary safety option, much like other driver–assist systems (i.e., automatic emergency braking or lane departure warning systems).

Key Partners In The DADSS Program


DADSS Program partners include:

  • Automotive Coalition for Traffic Safety (ACTS), a Virginia nonprofit funded by the world's leading automakers
  • U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA)
  • 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.-private partnerships like DADSS have led to innovations that enhance our everyday lives, such as internet, GPS, and the microchip.

DADSS Driven To Protect Discovery Hub


The learning modules below allow you to:

  • Explore how alcohol is absorbed, processed and eliminated by the human body
  • Learn how alcohol impairs your ability to safely operate a motor vehicle
  • Obtain actionable information so you can avoid the dangers associated with drunk driving
  • Find out how the novel DADSS technologies currently under development and testing will protect you and other motorists on the road in the future

There are also Science, Technology, Engineering, and Math (STEM) modules available so students can learn about the science and engineering behind the DADSS technologies.
