Drinking and driving wasn't made illegal by a single nationwide law but evolved through state-by-state legislation starting in the early 1900s.

Origins in the US

Massachusetts pioneered the first state ban in 1907, prohibiting driving "while drunk," though without specific blood alcohol limits—judges relied on officer judgment. New York followed in 1910 with the first explicit U.S. law criminalizing driving while intoxicated, setting a precedent that spread quickly. California joined in 1911, and by the 1930s, all states had some form of restriction, spurred by rising car ownership and Prohibition-era awareness (1920-1933).

Key Milestones

Here's a timeline of pivotal developments:

Year| Event
---|---
1906| New Jersey enacts early intoxicated driving ban.6
1907| Massachusetts passes first U.S. statewide law.1
1910| New York criminalizes DUI specifically.35
1911| California bans it, fueling national trend.1
1931| Drunkometer invented for roadside BAC testing.1
1988| Federal standards push uniform BAC limits (0.08% today).1

Early penalties were mild fines; modern ones include jail, license suspension, and ignition interlocks.

Evolution and Enforcement

Laws toughened post-WWII with breathalyzers (1950s) and Mothers Against Drunk Driving's advocacy in the 1980s, lowering BAC thresholds and adding zero- tolerance for minors. No federal criminal ban exists—it's state-regulated, explaining variations like stricter rules in California.

"DUI was already illegal... You could drive with an open beer as long as you weren't drunk back then." – Reddit discussion on historical norms.

Global Context

The first drunk driving arrest was in 1897 London; U.S. states mirrored Europe's gradual crackdown amid auto booms. Today, alcohol-related crashes kill ~13,500 yearly in the U.S., driving ongoing reforms.

TL;DR: Illegal state-by-state from 1907 (Massachusetts first), nationwide coverage by 1930s; tech and activism sharpened rules since.
