Driver Qualification File Support & Checklist

A DQ—short for driver qualification—file is a paper or electronic file created and maintained by a motor carrier on all drivers that operate commercial motor vehicles under its USDOT number. DQ files are mandated by Part 391 of the Federal Motor Carrier Safety Regulations and must contain specific documents evidencing each driver’s qualifications to operate a commercial vehicle, including, for example, motor vehicle records, medical examiner certificates, and road test certifications, to name a few.
