It could be available as soon as 2026.
This month, Congress passed a $1 trillion infrastructure bill that also includes a new rule to automakers. All new cars will have to be equipped with drunk driver monitoring systems by 2026. It’s not clear how automakers will accomplish this goal. They must first find the technology to meet the requirements of the government, which could delay implementation well past the 2026 deadline.
This is a difficult task for automakers. The current technology allows an ignition interlock system that connects to a breathalyzer to be used by some drunk drivers. This requires them to blow into it before they are allowed to start their vehicle. Drivers who just want to get to work on Monday mornings in the coldest fall weather will not find it necessary to overcome this hurdle. Many people find it a little too government-involved. Automakers will need to be creative. They already do in some cases.
Automakers have installed driver monitoring systems to ensure drivers pay attention on the roads since the introduction of semi-autonomous driving assistance systems. Today’s cars are not fully autonomous. The systems available today require that the driver pay attention behind the wheel, even when they’re not in control. The car will stop if the driver isn’t paying attention. Automakers also monitor driver drowsiness and will take a break if they observe certain symptoms.
Combining the two systems could be the best way for automakers to help the government reduce drunk driving deaths. According to the NHTSA (which is approximately 10,000 people), nearly 30% of traffic deaths each year are alcohol-related. Automakers are required to install a rear seat reminder system in order to notify parents if children are left behind. According to the Associated Press, this mandate could be in place by 2025.
