President Biden Signs Law That Will Require Cars To Detect Drunk Drivers

President Joe Biden has signed a landmark bill into law that will require cars to spot intoxicated drivers in the coming years. This is expected to save thousands of lives annually with the potential to expand abroad, advocates say.

To achieve this safety mandate,  breath-sniffing sensors and finger-scanning detectors are to be installed in new cars to spot inebriated drivers.

This legislation spurs tough questions about what technology can be trusted to do.

However, the legislation signed into law this week by President Joe Biden has also left skeptics to question whether vehicles could refuse to operate due to a false positive or effectively become witnesses against their owners in criminal cases.

Ultimately it is up to American regulators to decide what could become international precedent-setting rules. They have not said much so far, but have a potentially extendable three years to work with.

The initial reaction though was euphoria for people who battle against alcohol-related crashes in the United States, which permits drivers to have a higher level of booze in their blood than many other developed nations and consistently records a death toll over 10,000 per year.

“I’m crying tears of joy today,” said Alex Otte, national president of anti-drunk-driving advocacy group MADD.

“This is the beginning of the end of drunk driving,” she wrote in a statement after Biden’s law signing ceremony Monday at the White House.

The devil is in the details of course, and one of the best options for fielding functional technology to meet the mandate has been under development since 2008 in a collaboration between carmakers and regulators.

As part of the Driver Alcohol Detection System for Safety (DADSS), researchers have developed tiny vent-like sensors that draw in a driver’s exhaled breath and test it.

Or the driver pushes the ignition button, which measures blood alcohol levels under the skin’s surface by shining an infrared-light through the person’s fingertip.

Anti-cheat functions are built into the system, which could prevent the car from starting or keep it from moving for drivers over the .08 percent blood alcohol limit in most US states, said Robert Strassburger, president of the Automotive Coalition for Traffic Safety (ACTS), which is supported by carmakers.
