when did usa start driving on the right
Left- and right-hand traffic In the late 1700s, traffic in the United States was RHT based on teamsters' use of large freight wagons pulled by several pairs of horses. The wagons had no driver's seat, so the (typically right-handed) postilion held his whip in his right hand and thus sat on the left rear horse. Seated on the left, the driver preferred that other wagons pass him on the left so that he could be sure to keep clear of the wheels of oncoming wagons.[13]
U.S. Route 66 U.S. Route 66 (US 66 or Route 66), also known as the Will Rogers Highway, the Main Street of America or the Mother Road, was one of the original highways within the U.S. Highway System. US 66 was established on November 11, 1926, with road signs erected the following year.[4] The highway, which became one of the most famous roads in the United States, originally ran from Chicago, Illinois, through Missouri, Kansas, Oklahoma, Texas, New Mexico, and Arizona before ending at Santa Monica, California, covering a total of 2,448 miles (3,940 km).[5] It was recognized in popular culture by both the hit song "(Get Your Kicks on) Route 66" and the Route 66 television show in the 1960s.
