The NTSB can’t issue such a regulation on its own but urged the National Highway Traffic Safety Administration (NHTSA) to do so. The NTSB said it “is recommending measures leveraging new in-vehicle technologies that can limit or prohibit impaired drivers from operating their vehicles as well as technologies to prevent speeding.”

If adopted, this would require “passive vehicle-integrated alcohol impairment detection systems, advanced driver monitoring systems or a combination of the two that would be capable of preventing or limiting vehicle operation if it detects driver impairment by alcohol,” the NTSB said. The agency urged the NHTSA to “require all new vehicles to be equipped with such systems.”
