Questions & Answers

Direct answers grounded in TruckCodex inspection data

will 172.204(a) put my truck out of service

No. Across our 13 million inspection records, 172.204(a) citations have resulted in a 0.0% out-of-service rate—none of the 4 all-time citations triggered an OOS placement. This is significantly lower than the 31.4% national average OOS rate across all FMCSR codes. Your truck can continue operating while you correct the shipping paper deficiency.

how many CSA points is 172.204(a)

This violation carries a CSA severity weight of 5 points. The number of points that appear in your CSA record depends on when the citation was recorded and the 30-day rolling window calculation used by FMCSA. A severity weight of 5 is relatively minor compared to high-severity violations, which reflect the non-critical nature of a missing emergency contact number on shipping papers.

172.204(a) what do I do immediately after being cited

Immediate steps:

  1. Locate the shipping papers for the hazmat load cited.
  2. Verify the emergency response phone number is present and legible—it must be the shipper's or carrier's 24-hour contact.
  3. Correct the papers before the next load or return trip if possible.
  4. Review your shipping paper process with dispatch to prevent future omissions.
  5. Document the correction for your records in case of DataQs review.

Since this is a documentation issue, not equipment failure, compliance is typically quick.

is 172.204(a) serious compared to other hazmat violations

It is far less serious than other hazmat shipping violations. Our data shows similar codes like general loading/unloading violations (177.834A-HMC) have a 99.2% OOS rate and over 3,954 citations, while placarding violations (177.817(a)) reach 97.9% OOS. By contrast, 172.204(a) has a 0.0% OOS rate with only 4 all-time citations. This reflects that a missing phone number is a documentation gap, not a hazard during transport.

can I contest 172.204(a) through DataQs

Yes. You can file a DataQs (Database Quality System) request to challenge the citation if you believe it was issued in error. Since 172.204(a) is a documentation finding on shipping papers, not an equipment or safety defect, contestation focuses on whether the emergency number was actually present and legible at the time of inspection. Gather a copy of the corrected shipping papers and any evidence of the number's presence. FMCSA will review your submission within a standard timeframe.

172.204(a) how often is this cited nationally

Rarely. Across our entire database of 13 million roadside inspections, 172.204(a) has been cited only 4 times all-time, with 0 citations in the last 12 months. It ranks #2480 out of 3,036 FMCSR codes by citation volume. This extremely low enforcement frequency suggests inspectors cite this violation only in clear-cut cases where the emergency number is entirely absent from shipping papers.

172.204(a) which carriers and states see this citation most

Our inspection records show this citation is so infrequent that it's scattered across small carriers: Reeves Construction Company (USDOT 367836), PI Jon Inc (USDOT 922559), Venezia Liquid Tank Lines Inc (USDOT 1079977), and Prest Xspress LLC (USDOT 2422487) each received 1 citation all-time. With only 4 citations nationally, no single state dominates. This underscores that 172.204(a) is not a systematic enforcement focus.

how urgent is fixing 172.204(a)

Fix it promptly, but it is not a crisis. Because the 0.0% OOS rate means no trucks are being pulled out of service and citations have dropped to zero in the past 12 months, enforcement pressure is minimal. However, shipping papers must be compliant for every hazmat load, so correct the emergency number on your papers before your next shipment to avoid re-citation and ensure regulatory compliance.
