What 383.25A6 means in plain language
FMCSR 383.25A6 prohibits a driver holding only a Commercial Learner's Permit (CLP) from operating a commercial motor vehicle that is transporting hazardous materials requiring placards. A CLP is a stepping stone credential—it allows supervised driving practice toward a full Commercial Driver's License (CDL), but it comes with strict limitations on what you can haul and in some cases who can be in the cab with you.
Hazmat placarding requirements exist because certain cargo poses safety risks to the public. The regulation recognizes that CLP holders haven't yet demonstrated the full competency needed to handle those elevated responsibilities. Operating a placarded hazmat load on a CLP means you've exceeded your permit authority, regardless of your experience or the length of the route.
If you received this citation, it means an inspector at roadside found you transporting placarded hazmat materials without holding a full CDL. The citation itself is non-negotiable on the legality front—either you had the proper license or you didn't.
What our enforcement data actually shows
Across 13 million inspections in our database, 383.25A6 citations are extremely rare. We've recorded only 3 all-time citations for this violation, with just 1 citation in the last 12 months and zero in the last 90 days. This code ranks #2551 of 3,036 FMCSR codes by citation volume.
What makes this code notable is its out-of-service rate. Every single citation on record—100% of the 3 cases—resulted in the vehicle and driver being placed out of service immediately. This is dramatically higher than the all-FMCSR average OOS rate of 31.4%. The reason is straightforward: operating hazmat without proper credentials is a hard stop. There is no discretion for continued operation.
The rarity of citations suggests most CLP holders understand this boundary. When violations do occur, they trigger a full enforcement response.
Who gets cited most
Our inspection records show 383.25A6 citations are so infrequent that geographic and carrier patterns are minimal. In the last 180 days, Missouri recorded 1 citation with a 100% OOS rate. No other state appears in the enforcement snapshot for this code during that window.
All-time, three carriers appear once each in our database: Select Drink Inc (USDOT 356497), Great Western Leasing and Sales LLC (USDOT 704697), and Raihan Trucking Inc (USDOT 4010590). This distribution reflects the overall rarity of the violation rather than any trend or pattern of non-compliance.
How severe is this compared to similar codes
To understand where 383.25A6 sits in the enforcement landscape, compare it to related Driver Fitness codes.
Code 383.23(a)(2)—operating a CMV in the wrong class of CDL—has generated 50,385 citations with a 98.4% OOS rate. That violation is roughly 16,800 times more common than 383.25A6, but similarly severe in enforcement outcome.
Code 383.23A2-LCDLN—operating without any valid CDL at all—shows 47,123 citations and a 98.6% OOS rate, again far more frequent but matching the certainty of out-of-service placement.
Code 391.41(a), Physical qualification general, presents a contrast: 42,270 citations but only a 16.2% OOS rate. That code catches drivers with medical or qualification issues that may be curable, so enforcement is more graduated.
The pattern is clear: credential violations (wrong class, no CDL, CLP exceeding scope) trigger near-universal out-of-service action. Medical or fitness issues allow for more case-by-case judgment.
How to avoid it
The fix for 383.25A6 is absolute: do not accept any load requiring hazmat placarding until you hold a full CDL. Here are concrete steps:
-
Before accepting a dispatch: Ask your dispatcher or load broker explicitly whether the shipment is classified as hazardous material under DOT rules. If it requires placards, decline the load if you hold only a CLP. No exceptions.
-
During pre-trip: Visual placarding is your second check. Look for diamond-shaped placards on all four sides of the cargo area. If you see any placard (flammable, oxidizer, toxic, radioactive, corrosive, etc.), do not operate the vehicle. Return to the terminal or staging area immediately.
-
Know your credentials: If you're unsure whether your permit is a CLP or a full CDL, review your state's license document now. CLP will be clearly labeled. A full CDL allows unrestricted hauling (within vehicle classification).
-
Communicate with your fleet: Ensure dispatchers know you hold a CLP. Many fleet safety systems automatically route non-CDL drivers away from hazmat loads, but manual verification is your safeguard.
-
Get your full CDL: If hazmat transport is part of your long-term plan, schedule the CDL skills test and pass it. The CLP is temporary; it's meant to be a bridge, not a permanent assignment restriction.
The data underscores that this violation is rare precisely because most drivers respect the boundary. The 100% OOS rate means there is zero tolerance for exception. Your safest strategy is to ask, verify, and refuse any ambiguous load until you hold full credentials.
