US agency takes first step to mandate anti-drink driving technology

WASHINGTON – US auto safety regulators said on Dec 12 they have begun the process that will eventually force carmakers to adopt new technology to prevent intoxicated drivers from starting vehicles.

In 2021, the US Congress directed the National Highway Traffic Safety Administration (NHTSA) to mandate a passive technology to try to avert more than 10,000 road deaths in the country annually. The law requires a new technology safety standard by November 2024 if the technology is ready.

There are a number of potential technologies under development that would prevent impaired people from starting a vehicle, including breath- or touch-based sensors to detect alcohol. Another potential option is using cameras to monitor eye movements to try to determine if drivers are intoxicated.

Still, NHTSA must be assured the technology works before it can require it, and then give automakers at least three years to implement it once it finalises rules.

“We are trying to see can we get it done, does the technology exist in a way that is going to work every time,” acting NHTSA administrator Ann Carlson said, adding that public acceptance of the technology would depend on its accuracy.

Ms Carlson said there were close to one billion separate daily driving journeys in the United States.

“If it’s 99.9 per cent accurate, you could have a million false positives,” Ms Carlson said. “Those false positives could be somebody trying to get to the hospital for an emergency.”

The NHTSA on Dec 12 published an “advance notice of proposed rulemaking” to begin the process of gathering information on how such technology could be developed and required.

Its regulatory notice details the research and technological advancements needed to finalise regulations and options for potential rules, citing “blood alcohol content detection, impairment-detection (driver monitoring), or a combination”.

Mothers Against Drunk Driving president Tess Rowland said the group was “very pleased” with NHTSA’s launch.

“We understand we still have a mountain to climb,” Ms Rowland said. “Victims and survivors are not going to let this die.”

In 2021, 13,384 people died in alcohol-impaired driving traffic deaths in the US, the most recent statistics available show.

Separately, Ms Carlson will tell a US House of Representatives committee on Wednesday that US traffic deaths fell 4.5 per cent in the first nine months of the year after sharply rising during the Covid-19 pandemic.

“While we are optimistic that we’re finally seeing a reversal of the record-high fatalities seen during the pandemic, this is not a cause for celebration,” Ms Carlson’s written testimony says. REUTERS
