86 countries now follow one road safety treaty — and it’s been working since 1968 C.E.
The Vienna Convention on Road Traffic, signed in November 1968, established shared rules of the road across dozens of nations — standardizing driver licensing, vehicle registration, and cross-border recognition in a single international framework. Today, 86 countries operate under its provisions, quietly reducing accidents and bureaucratic friction for millions of travelers. What makes it remarkable is both its durability and its adaptability: a Cold War-era treaty is now being amended to address self-driving vehicles. It remains one of the most consequential — and least celebrated — achievements in international cooperation.
