When the transportation law book was established?

The establishment of transportation laws can vary by country and region. In the United States, transportation laws have been established over many years through various legislative acts and regulations. Some of the key transportation laws in the US include the Federal-Aid Highway Act of 1956, the National Traffic and Motor Vehicle Safety Act of 1966, and the Clean Air Act of 1970. These laws have been amended and updated over time to address changing transportation needs and challenges.
