A part of the rally course in which no specified speed need be maintained. Either an exact time for passage or a restart time from the end of the transit zone must be given. At least an approximate distance for the length of the transit zone shall be provided. A transit zone is a free zone.

The area surrounding a port of entry in a coastal country that serves as a storage and distribution centre for the convenience of a neighbouring country — a land-locked country, for example — lacking adequate port facilities or access to the sea. A transit zone is administered so that goods in transit to and from the neighbouring country are not subject to the customs duties, import controls, or many of the entry and exit formalities of the host country. A transit zone is a more limited facility than either a free trade zone or free port.

A part of a rally route in which there are no timing controls and in which no specific speed need be maintained. Either an exact time for passage, or a restart time from the end of the transit zone must be given. An approximate distance for the length of the transit zone is desirable.
