Direct answers grounded in TruckCodex inspection data
No. Across our inspection records, 374.201(b) has a 0.0% out-of-service rate—none of the 2 all-time citations in our database resulted in an out-of-service order. This is significantly lower than the 31.4% average out-of-service rate across all FMCSR codes. While the violation is on your record, it will not immediately ground your vehicle.
374.201(b) ranks #2651 of 3,036 FMCSR codes by citation frequency, making it one of the rarer violations in the database. Its 0.0% out-of-service rate contrasts sharply with peer codes in the same category—for example, 376.11(d)(1) has 6,383 citations with a 0.0% OOS rate, and 999 has 4,802 citations with a 12.1% OOS rate. The low citation count and zero OOS enforcement suggest this is a lower-priority violation in roadside enforcement.
Enforcement of this code is extremely rare. Our records show zero citations for 374.201(b) in the last 12 months and zero in the last 90 days. The only 2 all-time citations in our 13M+ inspection database occurred in the past, indicating this is not an active enforcement focus for state troopers or federal inspectors at present.
Yes. If you believe the citation was issued in error—for example, if the inspector misread a document, miscalculated a record, or misidentified a vehicle condition—you can file a DataQs (DataBase Quality System) challenge with FMCSA within 90 days of the violation date. Provide supporting evidence such as maintenance records, photographs, or corrected documentation. Given the rarity of this citation, documentation errors are worth investigating.
Our inspection records show only 2 all-time citations for 374.201(b). Both were issued to small carriers: TORNADO BUS COMPANY (USDOT 565859) received 1 citation, and ANTELOPE VALLEY AIRPORT EXPRESS INC (USDOT 709384) received 1 citation. The extremely limited enforcement history suggests this violation is not a systemic problem for any carrier type.
Priority depends on the violation type. Since this code is not out-of-service eligible and has a 0.0% OOS rate, you are not at immediate risk of being roadside-pulled. However, correct the deficiency within 30 days to demonstrate good-faith compliance and prevent accumulation of violations on your safety record. The extremely low enforcement volume—zero citations in the last 90 days—suggests inspectors are not actively focusing on this code, giving you reasonable time to address it.
Our records show only 2 vehicles cited for 374.201(b): one CHAMPION and one VOLVO. The small sample size makes it impossible to identify a pattern by vehicle make or type. This reinforces that 374.201(b) is an exceptionally rare citation, not concentrated in any particular equipment category.
