The Transportation Worker Identification Credential and the Hazardous Materials Endorsement background-check programs have not been affected by the government shutdown, American Trucking Associations officials confirmed.

Freight transportation officials said their companies suffered only minimal effects from the federal government shutdown last week but added they were preparing for disruptions if the budget dispute drags on.
