Pursuant to Senate Report 115-138 accompanying Senate Bill 1655 and the Joint Explanatory Statement accompanying the Consolidated Appropriations Act, 2018 (P.L. 115-138), the letter report provides information on the Federal Motor Carrier Safety Administration’s (FMCSA) new Consent Agreement Tracking System. Consent agreements allow motor carriers to continue to operate with specific requirements while corrections to deficiencies or violations are addressed. Congress directed FMCSA to submit a report on the consent agreement tracking system’s performance and, more specifically, to indicate if the system succeeded in providing the expected efficiencies. Congress also asked that FMCSA determine if additional enhancements and resources are necessary to assist with the monitoring and enforcement of high-risk carriers.
