As the UK Motor Car Act 1903 placed a speed restriction of on cars within the United Kingdom, the Secretary of the Automobile Club of Britain and Ireland approached the authorities in the Isle of Man to seek permission to race cars on public roads. The Highways (Light Locomotives) Act 1904 passed by Tynwald gave permission to use local roads for the Highroads Course for the 1904 Gordon Bennett Trial.
