When did drinking and driving laws come into effect?

Drinking and driving laws began to emerge in the early 20th century, with the first known law enacted in New York in 1910, which made it illegal to drive while intoxicated. Over the years, many states and countries followed suit, implementing stricter regulations and penalties. The movement gained significant momentum in the 1980s, leading to the establishment of the legal blood alcohol concentration (BAC) limit of 0.08% in the United States. Today, these laws continue to evolve in response to ongoing public safety concerns.
