What 390.33 means in plain language
390.33 addresses administrative and general compliance requirements for commercial motor vehicle operations. The regulation establishes baseline expectations for how carriers and drivers must maintain their operational records and meet certain organizational standards set by the Federal Motor Carrier Safety Administration (FMCSA).
For drivers, this typically involves ensuring that required documentation, permits, or carrier-level compliance measures are in place and properly maintained. The violation itself doesn't involve unsafe mechanical conditions or dangerous driving behavior—it's about the paperwork and procedural side of operations.
What our enforcement data actually shows
Across our 13 million+ roadside inspection records, 390.33 is extremely rare. We have recorded 20 citations all-time for this code, with 0 citations in the last 12 months and 0 in the last 90 days. This makes 390.33 ranked #1938 out of 3,036 FMCSR codes by citation volume.
What's striking about this code is its out-of-service rate: 80.0% of the 20 citations resulted in an out-of-service placement. This is dramatically higher than the all-FMCSR average OOS rate of 31.4%—meaning inspectors treat these violations seriously when they do occur. Of the 20 total citations, 16 resulted in out-of-service status and 4 did not.
The near-zero enforcement activity over the past 90 days and last 12 months suggests that either the violation is being caught and corrected before reaching roadside inspection, or carriers are maintaining strong compliance with this particular requirement.
Who gets cited most
Our inspection records show that 390.33 citations are concentrated among passenger and specialty transportation fleets. The carrier with the most citations in our database is KINGKONG TOUR INC (USDOT 4048552) with 3 citations. FIRST STUDENT INC (USDOT 354406) and HISTORIC BOSTON TOURS LLC (USDOT 3978066) each account for 2 citations.
Because the total citation volume is only 20 across our entire database, state-level breakdowns are not meaningful enough to highlight. The enforcement pattern is too sparse to point to specific high-risk regions.
How severe is this compared to similar codes
390.33 sits in the General/Admin category alongside codes like 390.21TB2-DOT (74,663 citations, 0.0% OOS rate) and 390.21T(b) (61,097 citations, 0.0% OOS rate). These peer codes are cited far more frequently—hundreds of times more in some cases—yet result in out-of-service status almost never.
Another peer code, 390.21(a) covering vehicle marking requirements, has 25,872 citations with a 0.0% OOS rate. The contrast is clear: 390.33 is cited rarely but almost always leads to serious enforcement action, whereas other administrative codes in the same family are cited far more often but rarely result in an out-of-service placement.
This suggests that when 390.33 does appear at roadside, the violation is systemic or egregious enough to warrant immediate out-of-service action. Administrative violations in this family are normally lower-severity, but 390.33 enforcement appears to follow a different threshold.
How to avoid it
Because 390.33 citations are so infrequent, your best defense is understanding your carrier's compliance obligations and your role in maintaining them:
-
Confirm carrier credentials and permits – Before or at the start of each shift, verify that your carrier's USDOT number, operating authority, and any required endorsements are current and properly displayed. Roadside inspectors verify these during every inspection.
-
Know your dispatch paperwork – Work with your carrier's safety department to ensure all required documentation for your route and load type is present and correct. Missing or incomplete paperwork at roadside can trigger administrative citations.
-
Maintain vehicle registration and inspection records – Keep your vehicle's registration, annual inspection certificates, and any required compliance placards visible and up-to-date. Administrative violations often stem from expired or missing documentation.
-
Communicate with your carrier's compliance team – If you're uncertain about any requirement or notice during pre-trip that something is missing (permits, markings, or documentation), report it immediately to your dispatcher or safety manager rather than taking the vehicle on the road.
-
Understand carrier-level responsibilities – Some 390.33 violations may originate from carrier-level non-compliance rather than driver error. Ask your fleet manager or safety officer to explain what specific measures they have in place to meet administrative requirements, so you know what to watch for during your own pre-trips.
