Just in time for the Super Bowl, Frito-Lay’s rolled out a new “Party Safe” Tostitos bag that doubles as a breathalyser, detecting if alcohol is present on a would-be driver’s breath.

If alcohol is detected, an array of LEDs shaped like a steering wheel will illuminate red; conversely, if no alcohol is detected during the test, the steering wheel will light up green, giving a digital thumbs-up to drivers, reports NFC World.

Unlike a police breathalyzer, which tests for varying amounts of alcohol concentration on the breath, the sensor in the bag is designed to detect “any” alcohol—meaning the bag will deter drivers from drinking even if their blood-alcohol concentration is within the legal limit. Thus, the bag essentially encourages total sobriety before driving.

“Our goal is to remove 25,000 cars from the roads that Sunday evening,” says Jennifer Saenz, Frito-Lay’s chief marketing officer, referring to Super Bowl Sunday.

“Whether watching the big game at a friend’s house or at a local bar, a safe ride home is just a few taps away.”

Frito-Lay has partnered with Uber and Mothers Against Drunk Driving (MADD) to offer discounted rides to Tostitos-munching drivers who’ve used the bag and tested positive for alcohol on their breath, making a safe ride a click away.
