What this BASIC means

The Hazardous Materials BASIC tracks 49 CFR Parts 171-180 — the Hazardous Materials Regulations (HMR). This BASIC only applies to carriers transporting hazmat in placardable quantities. CSA threshold is the <strong>50th percentile</strong> (lower than other BASICs) because hazmat incidents have catastrophic potential. Common violations are paperwork-driven: shipping papers don't match placards, missing emergency response info, training records expired, or no Hazmat Security Plan when required.

Top violations in this BASIC

177.823 (placards not maintained or wrong) is the most-cited hazmat violation. Placards must match the shipping papers and stay legible. 172.704 (driver not trained or training expired) requires initial training plus recurrent every 3 years. 177.804 (driver not familiar with regulations) covers everything from emergency response procedures to forbidden parking locations.

How to lower your Hazardous Materials Compliance BASIC

Match shipping paper, placards, and BOL exactly before dispatch. Maintain a current Hazmat Security Plan per 172 Subpart I if you haul Table 1 quantities. Train drivers initially via FMCSA-approved program (CDL HazMat endorsement training counts), then every 3 years. Don't accept loads with incomplete or wrong paperwork — refuse them. Most hazmat violations are caused by accepting bad paperwork from the shipper.

Frequently Asked Questions

What is the Hazardous Materials Compliance BASIC?
The Hazardous Materials Compliance BASIC is one of seven Behavior Analysis and Safety Improvement Categories in FMCSA's Safety Measurement System (SMS). The Hazardous Materials BASIC tracks 49 CFR Parts 171-180 — the Hazardous Materials Regulations (HMR). This BASIC only applies to carriers transporting hazmat in placardable quantities. CSA threshold is the 50th percentile (lower than other BASICs) because hazmat incidents have catastrophic potential. Common violations are paperwork-driven: shipping papers don't match placards, missing emergency response info, training records expired, or no Hazmat Security Plan when required.
What CSA percentile triggers FMCSA intervention for Hazardous Materials Compliance?
FMCSA's intervention threshold for Hazardous Materials Compliance is the 50th percentile. Once a carrier crosses, FMCSA can issue a Warning Letter, conduct an Off-Site Investigation (request documents remotely), conduct an On-Site Focused Investigation (auditor visits but only reviews this BASIC), or a full Compliance Review (auditor reviews everything). Compliance Reviews are how Conditional or Unsatisfactory safety ratings happen — those can shut down a carrier.
How can I see my carrier's Hazardous Materials Compliance score?
Go to FMCSA's SMS website (ai.fmcsa.dot.gov/sms), enter your USDOT number, and look at the BASIC scorecard. Each BASIC shows your percentile rank, the violations contributing, and the time-weighting. The data updates monthly. Drivers can see their own PSP report at the FMCSA Pre-Employment Screening Program portal — it covers driver-side BASICs (Unsafe Driving, HOS, Driver Fitness, Controlled Substances).
Which violations in this BASIC are out-of-service eligible?
10 of the 10 catalogued Hazardous Materials Compliance violations are out-of-service eligible. OOS-eligible means the inspector can take the driver or truck off the road at the inspection site — the truck/driver cannot continue until the defect is corrected. Browse the OOS-eligible list above to see which specific codes can put you OOS.
How long do Hazardous Materials Compliance violations stay on my CSA score?
All BASICs use the same 24-month time-weighting: 3× points months 0-6, 2× months 7-12, 1× months 13-24, then drops off. Driver-side violations also appear on the driver's PSP report for 36 months. If you successfully challenge a citation via DataQs, it can be removed from CSA — but you have to file the challenge yourself within 24 months.
