Congressional Budget Office Cost Estimate: H.R. 3813: Combating Human Trafficking in Commercial Vehicles Act [open pdf - 90KB]
"H.R. 3813 would require the Department of Transportation (DOT) to designate an official to coordinate agency activities designed to prevent and address human trafficking, establish an advisory committee on human trafficking within DOT, and to authorize the use of certain grant funds administered by the Federal Motor Carrier Safety Administration (FMCSA) for activities related to preventing human trafficking. Using information from DOT, CBO [Congressional Budget Office] estimates that implementing the provisions of the bill would require one or two additional employees per year over the 2019-2022 period, at a total cost of $1 million. Such spending would be subject to the availability of appropriated funds."
