Information for Respondents

Overview

The Vehicle Inventory and Use Survey (VIUS) is sponsored by the Bureau of Transportation Statistics, the Federal Highway Administration, and the U.S. Department of Energy, and is conducted by the U.S. Census Bureau.

VIUS provides data on the physical and operational characteristics of the nation’s truck population. Its primary goal is to produce national and state-level estimates of the total number of trucks and truck miles.

Prior to 1997, VIUS was known as the Truck Inventory and Use Survey (TIUS). It was renamed to account for areas of future expansion, including the addition of automobiles and buses.

Legal Authority and Confidentiality

YOUR RESPONSE IS REQUIRED BY LAW. Title 13 United States Code (U.S.C.), Sections 131 and 182 authorize this collection. Sections 221, 224, and 225 require your response. The U.S. Census Bureau is required by Section 9 of the same law to keep your information CONFIDENTIAL and can use your responses only to produce statistics.

This collection has been approved by the Office of Management and Budget (OMB). The eight-digit OMB approval numbers are 0607-0892 and 0607-1021 and appear on the electronic instrument and the paper questionnaire used for this survey. Without this approval we could not conduct this survey.

The Census Bureau is not permitted to publicly release your responses in a way that could identify you, your business, organization or institution. Per the Federal Cybersecurity Enhancement Act of 2015, your data are protected from cybersecurity risks through screening of the systems that transmit your data.
