Congressional Budget Office Cost Estimate: H.R. 3814: No Human Trafficking on Our Roads Act [open pdf - 89KB]
"H.R. 3814 would permanently prohibit anyone who has used a commercial motor vehicle to commit a felony involving severe human trafficking from operating a commercial motor vehicle. Under current law, state agencies are responsible for issuing commercial driver's licenses and complying with the requirements in the bill. The Federal Motor Carrier Safety Administration (FMCSA) has two full-time employees who provide training for state inspectors and investigators who combat criminal activities such as drug trafficking. H.R. 3814 would require FMCSA to expand that effort."
