Hiring CDL Drivers: Understanding FMCSA Regulations for Safety Screening

As an employer, ensuring the safety of your commercial motor vehicle (CMV) operations is crucial. One key aspect of maintaining safety standards is hiring qualified and responsible CDL (Commercial Driver’s License) drivers. The Federal Motor Carrier Safety Administration (FMCSA) has established regulations (49 CFR Part 391) that employers must follow when screening CDL drivers before they can perform safety-sensitive functions. In this blog post, we will dive into the FMCSA regulations and explore how you can hire CDL drivers while adhering to these guidelines. 


The FMCSA, a division of the United States Department of Transportation, oversees the safety and regulation of commercial motor vehicles. Their primary goal is to reduce crashes, injuries, and fatalities involving CMVs. To achieve this, the FMCSA has implemented comprehensive regulations (49 CFR Part 391) that employers must comply with when employing CDL drivers. 

Understanding FMCSA Regulations (49 CFR Part 391) for Hiring CDL Drivers 

The FMCSA requires employers to conduct a thorough screening process before hiring CDL drivers. This process is designed to ensure that only qualified and competent individuals are entrusted with the responsibility of operating CMVs. Let’s explore the key elements of the FMCSA regulations (49 CFR Part 391) for hiring CDL drivers: 

  • Driver Qualification File (DQF): Employers must create and maintain a DQF for each CDL driver they hire. The DQF should include essential documents such as the driver’s application for employment, driving records, previous employment verification, and a record of pre-employment tests and enrollment into a random testing program. 
  • Medical Examinations: CDL drivers must undergo a medical examination conducted by a certified medical examiner to assess their physical fitness for operating CMVs. Employers must retain the medical examiner’s certificate in the driver’s DQF. 
  • Background Checks: Employers must perform comprehensive background checks on CDL drivers, including inquiries into their driving records, employment history, and criminal records. This step ensures that the driver has a clean track record and meets the requirements for safe driving. 


Q: Are all CDL drivers subject to FMCSA regulations for screening? 

A: Yes, any CDL driver operating a CMV in interstate commerce is subject to FMCSA regulations (49 CFR Part 391) for screening. 

Q: How often should employers update the Driver Qualification File? 

A: It is crucial to monitor drivers throughout the year to ensure the ongoing safety of the company.  Employers must update the DQF annually, including a review of the driver’s driving records and any new information relevant to their qualifications. 

Q: Can employers use third-party services for pre-employment tests and random testing program enrollment? 

A: Yes, employers can engage third-party service providers to conduct pre-employment tests and facilitate enrollment into random testing programs as long as the providers meet the FMCSA requirements.
