Frequently Asked Questions

The Frequently Asked Questions (FAQs) are questions and answers about Compliance, Safety, Accountability (CSA) that the Federal Motor Carrier Safety Administration (FMCSA) compiled to assist the public. As questions come in through the website, FMCSA adds them to the database along with their answers. If you do not see your question or topic addressed, please contact us by submitting a feedback form. We will respond to you directly and consider your question for inclusion in the FAQs.

The FAQ area has recently been enhanced. Users can now search FAQs by stakeholder group, topics (displayed on the left side of the page), or by entering a keyword below. Choosing “Show All” will display the entire collection of FAQs.

  1. What is Compliance, Safety, Accountability (CSA) at the highest level? Answer

    The Federal Motor Carrier Safety Administration's (FMCSA) regulations remained the same after CSA implementation in December 2010, though CSA does change how FMCSA prioritizes carriers for enforcement and how it enforces compliance. Generally, CSA affects carriers subject to the Federal Motor Carrier Safety Regulations (FMCSRs), carriers transporting passengers or cargo in interstate commerce, and carriers of hazardous materials in intrastate commerce. CSA may also include carriers whose State requires that they obtain a U.S. DOT Number. FMCSA has provided detailed answers to questions about the general applicability of the FMCSRs. CSA will enact three major changes:

    1. There is a new Safety Measurement System (SMS) that gives a more comprehensive profile of carriers and drivers, better pinpoints the source(s) of safety problems, and more effectively identifies high crash-risk behavior. It is important that all FMCSA stakeholders understand the new SMS. To better understand how SMS works, read the SMS Methodology, and this SMS factsheet.
    2. There is a new interventions process as well as state-of-the-art tools that are more efficient and effective in the enforcement and compliance process. They institute a wider range of interventions to influence compliance earlier and match intervention to the corresponding level of safety performance. It is important that all FMCSA stakeholders understand this new interventions process. The interventions are outlined in this factsheet.
    3. There is a proposed change to the Safety Fitness Determination (SFD). The proposed change will assess the safety performance of a larger segment of industry. Furthermore, it will be based on roadside performance and intervention results, and ratings will be updated more often in order to convey current safety conditions. Once the final rule is passed, it will be important for all FMCSA stakeholders to understand it. To read more on the new proposed SFD, refer to pages 53487-53488 of this rulemaking notice located on FMCSA's Website.
