What 398.7 means in plain language
FMCSR 398.7 requires that motor vehicles used to transport migrant workers must be properly inspected and maintained. This is a specialized vehicle maintenance standard that applies specifically to carriers operating migrant worker transportation operations. The regulation ensures that vehicles carrying migrant workers meet the same rigorous inspection and upkeep standards as any commercial truck—with no shortcuts or exceptions because of the cargo type.
If you operate a truck that transports migrant workers, every component that affects safety must be in working order before you leave the lot and throughout the life of the vehicle. This includes brakes, lighting, tires, steering, and structural integrity. The responsibility falls on both the carrier and the driver to document that these inspections happen regularly and that any defects are repaired promptly.
What our enforcement data actually shows
Across 13 million roadside inspections in our database, 398.7 has generated only 9 citations all-time, with 0 citations in the last 12 months and 0 in the last 90 days. This makes 398.7 ranked #2230 out of 3,036 FMCSR codes by citation volume—one of the least-cited vehicle maintenance codes on record.
None of the 9 all-time citations resulted in an out-of-service order. The OOS rate for 398.7 is 0.0%, which is significantly lower than the all-FMCSR average OOS rate of 31.4%. This stark difference reflects both the rarity of enforcement and the fact that when inspectors do cite this code, they typically view the violation as correctable without immediately grounding the vehicle.
Who gets cited most
Our inspection records show that citations for 398.7 are so infrequent that no single state or carrier dominates the enforcement picture. The top carriers in our all-time data each received only 1 citation: examples include Southern Glazer's Wine and Spirits LLC (USDOT 420647), VRP Transportes de Mexico S de RL de CV (USDOT 662058), and One World Logistics of America Inc (USDOT 811350). Because enforcement volume is minimal, geographic or carrier-specific patterns are not statistically meaningful.
How severe is this compared to similar codes
In the Vehicle Maintenance category, 398.7 sits at the far low end of enforcement intensity. By comparison, 393.9(a)—Inoperable required lamps—has generated 660,737 citations with a 15.4% OOS rate. Another peer code, 396.3(a)(1) covering general inspection and repair maintenance, shows 236,919 citations and a 45.3% OOS rate. Even 396.17(c), which addresses proof of periodic inspection, has accumulated 198,331 citations, though its OOS rate matches 398.7 at 0.0%.
The near-zero citation volume for 398.7 suggests either that carriers transporting migrant workers are exceptionally compliant with vehicle maintenance standards, or that inspectors rarely encounter this specific violation in the field. Either way, the enforcement landscape is vastly quieter than mainstream maintenance codes.
How to avoid it
While 398.7 violations are rare, they are preventable with disciplined pre-trip and periodic maintenance routines:
-
Document every inspection. Keep a written or digital log of all vehicle inspections before each trip. Record the date, odometer reading, inspector name, and any defects found. This documentation is your proof of compliance if an inspector asks.
-
Perform a thorough pre-trip walk-around. Before leaving the lot with migrant workers on board, check brakes, tires, lights (headlamps, taillamps, brake lamps, turn signals), mirrors, wipers, horn, steering responsiveness, and structural condition. If you drive Freightliners or Internationals—the two most common makes in our citation data—familiarize yourself with their specific inspection points.
-
Repair defects immediately. If your pre-trip or periodic inspection reveals any defect, do not dispatch the vehicle. Have it repaired and re-inspected before carrying workers. A citation for operating an uninspected vehicle is far more likely than a 398.7 citation, and it carries serious consequences.
-
Use a certified mechanic. Assign maintenance work to mechanics who understand FMCSR standards and can sign off on repairs. Do not attempt to "fix" a brake issue or lighting problem yourself unless you are trained and authorized to do so.
-
Schedule regular maintenance intervals. Do not wait for an inspection to fail before servicing critical components. Follow the vehicle manufacturer's maintenance schedule and the carrier's internal policies, whichever is more stringent.
-
Understand your carrier's migrant worker transport operations. If your employer operates migrant worker routes, ask them for their inspection and maintenance procedures specific to this service. Some carriers may have additional internal standards beyond the minimum FMCSR requirement.
