According to Federal Motor Carrier Safety Administration (FMCSA) regulations, a strict sequence of documentation and repair must occur when a safety-critical defect is discovered at the end of a shift. Arrange the following procedures in the mandatory chronological order required to legally resolve an out-of-service defect and return the commercial motor vehicle to service.
- 1The completing driver measures the brake pushrod stroke, finds it exceeds the maximum allowable limit, and records this safety-critical defect on the written DVIR.
- 2The motor carrier or an authorized mechanic performs the necessary adjustments or replacements to correct the identified out-of-service brake defect.
- 3The repairing mechanic or authorized carrier agent signs the original DVIR to officially certify that the required repairs have been completed.
- 4The next assigned driver reviews the prior day's completed DVIR as part of their mandatory pre-trip inspection routine.
- 5The next assigned driver signs the DVIR to acknowledge the mechanic's repair certification prior to operating the commercial motor vehicle.
Answer
The correct chronological sequence is: Driver documents the defect -> Mechanic repairs the defect -> Mechanic certifies the repair -> Next driver reviews the DVIR -> Next driver signs the acknowledgment.
The FMCSA dictates a strict chain of custody for safety-critical defects to ensure accountability. The sequence begins with the completing driver's documentation of the defect. Next, the mechanic performs the required repair and immediately certifies it by signing the DVIR. Finally, the next assigned driver must review this completed document and sign it to acknowledge the repair before taking control of the vehicle.
