Last year’s Infrastructure Investment and Jobs Act includes a provision to require alcohol-detection technology on all new passenger vehicles by 2024. “One of the most promising of the available interventions uses an infrared light, installed on a steering wheel or push-button ignition, to detect alcohol in the bloodstream through a driver’s fingertips, per Curbed. “If the blood-alcohol concentration is over .08 percent, the car won’t start.” However three Republican senators are planning to introduce legislation to repeal it.
