This is a permit issued by the base jurisdiction to be carried in a qualified motor vehicle in lieu of the permanent annual decals. A temporary permit is vehicle-specific and is valid for a period of thirty (30) days to allow the carrier adequate time to affix the permanent decals. The temporary IFTA permit will be issued only to currently registered IFTA carriers.
