The U.S. drives on the right, in LHD (left-hand-drive) vehicles.
The first keep-right law in the United States, passed in 1792, applied to the Philadelphia and Lancaster Turnpike, between Lancaster and Philadelphia. New York (in 1804) and New Jersey (in 1813) also enacted keep-right rules.
Early American motor vehicles were produced in RHD, following the practice established by horse-drawn buggies. This changed in the early years of the 20th century: Ford changed to LHD production in 1908 with the Model T,[88] and Cadillac in 1916.
