New drink-driving technology could soon be a fixture in all cars. Here’s why it’s a game changer

While drink driving fatalities and injuries have declined in recent decades, it still remains a major problem on Australian roads.

Blood alcohol concentration (BAC) limits have helped since they were put in place over 25 years ago, but new technology may now be able to stop drink driving altogether.

In the US, the massive infrastructure bill passed by Congress last year mandated car manufacturers equip vehicles with advanced drink-driving prevention technology. These systems can either monitor a driver’s performance to detect if they are impaired, or test a driver’s BAC to determine if it’s above the legal limit.

The US Department of Transportation has been given latitude to choose the type of system that manufacturers use, with a requirement for it to be installed in new cars by 2027.

Similar efforts have been recommended in Australia, with Victoria reportedly being the only jurisdiction outside the US to trial the new technology.
