A single trip permit is valid for a set window of time, meaning the load must move from the permits origin to destination within that window or the carrier must obtain an extension of the current permit or refile for a new permit. The number of days a single trip a permit is valid ranges from 3 days in a number of states to 15 days in Indiana. Carriers must coordinate the windows that permits are valid when making multi-state moves to ensure the permit will not expire en route to the final destination.
