The US National Transportation Safety Board (NTSB) yesterday recommended that all new vehicles be equipped with alcohol detection systems that can stop people from driving when drunk.

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."
