Vehicle Inventory and Use Survey - Discontinued

Skip navigation


The Geographic Area Series consists of 52 data releases available for the United States, each state, and the District of Columbia. All files are released as pdf (portable document format) files. Available microdata files contain unaggregated records for individual trucks by state. The records are masked to avoid possible disclosure of individual vehicles and owners.

Prior to 1997 the survey was known as the Truck Inventory and Use Survey (TIUS) .
