Direct answers grounded in TruckCodex inspection data
No. Across our inspection database, 180.336 has never resulted in an out-of-service order—our all-time OOS rate for this code is 0.0%. Of 1 citation issued since records began, 0 resulted in immediate vehicle removal. Compare that to the 31.4% national average OOS rate across all FMCSR codes: 180.336 is among the least likely violations to trigger roadside removal. However, the violation itself still counts against your record and requires correction.
Much less serious. Our inspection records show 180.336 has been cited only 1 time all-time, ranking it #2796 out of 3,036 FMCSR codes by enforcement volume. For context, peer hazmat loading violations like 177.834A-HMC carry a 99.2% OOS rate and 3,954 citations, while placarding violations (177.817a) hit 97.9% OOS. The 0.0% OOS rate on 180.336 indicates inspectors view it as a documentation or minor compliance issue rather than an immediate safety threat comparable to loading, placarding, or emergency response failures.
Rarely. Across our 13 million+ roadside inspection records, 180.336 has generated only 1 citation total—issued in April 2025. In the last 90 days, it has not been cited at all. This is an exceptionally low-frequency violation. It does not appear in monthly enforcement patterns and is not a common focus area for roadside inspectors, making it a statistical outlier rather than a widespread compliance problem.
Step 1: Request a copy of the inspection report and citation details—verify the specific finding.
Step 2: Review the hazardous materials rules applicable to your load or transport method.
Step 3: Correct any documentation, training, or process gaps before your next hazmat shipment.
Step 4: Contact your carrier's safety department if you're a company driver; if you're an owner-operator, consult your hazmat compliance specialist.
Step 5: Consider contesting through DataQs within 15 days if the finding is factually incorrect or if records were incomplete at the time of inspection.
Since this violation carries 0% OOS enforcement, you are not stopped immediately—but the citation still creates a compliance record.
Yes. The FMCSA DataQs (Crash/Inspection Retrieval) system allows you or your carrier to challenge any citation within 15 days of issuance if the factual finding is incorrect or if documentation supporting compliance was not available to the inspector. Given that 180.336 is rarely enforced, a dispute is likely to succeed if you can provide evidence the violation did not occur or if records were overlooked. Submit your challenge with supporting documents through your carrier's FMCSA portal or directly to FMCSA.
Across our inspection records, only 1 citation for 180.336 has been issued all-time, attributed to PC TRANSPORT INC (USDOT 191414). This extremely low citation volume reflects the rarity of this violation. No other carriers appear in the enforcement data, indicating it is not a systemic compliance issue for any particular fleet or carrier type. Individual driver behavior, specific load type, or a one-time documentation gap is far more likely the cause than a carrier-wide problem.
Low urgency in the immediate sense—it will not ground your truck—but it still requires correction before your next relevant operation. With 0 citations in the last 90 days and only 1 in the past 12 months, 180.336 is not an active enforcement priority. However, do not ignore it: correct the documented issue within 30 days to avoid compounding violations or CSA profile damage. If the violation involves hazmat documentation or training, address it before accepting another hazmat load.
Both. Under FMCSA CSA guidelines, safety violations attach to your personal driver record and to your carrier's safety profile. A violation citation affects how you appear to future employers and impacts your carrier's BASIC scores (Behavior Analysis and Safety Improvement Categories), which affect insurance rates, audit triggers, and market reputation. Although 180.336 alone is low-frequency, any citation on your record is visible to carriers and regulators during compliance reviews.
