A Connecticut family whose son was killed by an impaired driver say a little-known part of the federal infrastructure bill will save thousands of lives on the road.

The provision requires new car makers to include technology that can slow down or stop a car if it detects high levels of alcohol coming from the driver.

Erin and Larry Hermann, whose son Kyle was killed by an impaired driver in Connecticut, say this is a game changer.

“It's not a breathalyzer, it's not an interlock. The average driver will not even know it's there,” Larry Hermann says. “This is a 100% preventable crime…No more families have to go through what Erin and I go through.”

The Hermann family and Mothers Against Drunk Driving New England met with Sen. Richard Blumenthal at a car dealership in Hamden to talk about the measure.

The deadline for installing the new technology is 2026.
