New technology to stop drunken driving mandated
Congress has created a new requirement for automakers: Find a high-tech way to keep drunken people from driving cars. It’s one of the mandates, along with a burst of new spending, aimed at improving auto safety amid escalating road fatalities in the $1 trillion infrastructure package that President Joe Biden is expected to sign soon.
Under the legislation, monitoring systems to stop intoxicated drivers would roll out in all new vehicles as early as 2026, after the Transportation Department assesses the best form of technology to install in millions of vehicles and automakers are given time to comply, according to an Associated Press article by Hope Yen and Tom Krisher.
Alex Otte, national president of Mothers Against Drunk Driving, called the package the “single most important legislation” in the group’s history that marks “the beginning of the end of drunk driving.”
“It will virtually eliminate the No. 1 killer on America’s roads,” she said.
Last month, the National Highway Traffic Safety Administration reported an estimated 20,160 people died in traffic collisions in the first half of 2021, the highest first-half total since 2006. The agency has pointed to speeding, impaired driving and not wearing seatbelts during the coronavirus pandemic as factors behind the spike.
Each year, around 10,000 people are killed due to alcohol-related crashes in the U.S., making up nearly 30% of all traffic fatalities, according to NHTSA. In every state, it’s illegal to drive drunk. Yet, one person was killed in a drunk driving crash every 52 minutes in the United States in 2019.
Currently, some convicted drunken drivers must use breathalyzer devices attached to an ignition interlock, blowing into a tube, and disabling the vehicle if their blood alcohol level is too high. The new legislation doesn’t specify the technology, only that it must “passively monitor the performance of a driver of a motor vehicle to accurately identify whether that driver may be impaired.”
Sam Abuelsamid, principal mobility analyst for Guidehouse Insights, said the most likely system to prevent drunken driving is infrared cameras that monitor driver behavior. That technology is already being installed by automakers such as General Motors, BMW and Nissan to track driver attentiveness while using partially automated driver-assist systems. The cameras make sure a driver is watching the road, and they look for signs of drowsiness, loss of consciousness or impairment. If signs are spotted, the cars will warn the driver, and if the behavior persists, the car will turn on its hazard lights, slow down and pull to the side of the road.
Abuelsamid said breathalyzers aren’t a practical solution because many people would object to being forced to blow into a tube every time they get into the car. “I don’t think it’s going to go over very well with a lot of people,” he said.
