What 392.10A4-RRC means in plain language
This citation means you operated a commercial motor vehicle carrying hazardous materials and did not come to a complete stop at a railroad grade crossing. Federal rules require that any driver transporting hazmat must treat railroad crossings with extra caution—you cannot proceed across the tracks without stopping, even if the crossing appears clear and no train is visible.
The regulation applies specifically to cargo tank vehicles carrying hazmat. If you're hauling fuel, chemicals, or other regulated materials, the stakes are higher than for standard freight. A train-hazmat collision creates catastrophic risk: explosions, toxic releases, derailments, and potential mass casualty events. The FMCSR enforces this with zero tolerance at the roadside.
What our enforcement data actually shows
Across our 13 million+ roadside inspection records, code 392.10A4-RRC has resulted in 39 all-time citations, with 26 citations in the last 12 months and 3 in the last 90 days. This code ranks #1701 out of 3,036 FMCSR codes by citation volume—making it a relatively uncommon violation nationally.
What matters most for your situation: the out-of-service rate on this code is 0.0%. Of the 39 citations ever issued, zero vehicles were placed out of service. By contrast, the all-FMCSR average OOS rate is 31.4%, meaning this violation almost never results in an immediate out-of-service order. However, rarity does not mean lenience. This is a hazmat-specific safety violation, and enforcement agencies treat railroad crossing failures as serious lapses in judgment.
Who gets cited most
Our inspection data shows citations concentrated in a handful of states over the last 180 days. Nebraska, Michigan, and Oklahoma each recorded 2 citations; Mississippi, Ohio, South Carolina, Utah, Arizona, West Virginia, and California each recorded 1. All of these citations resulted in zero out-of-service placements.
Among carriers, our records show fleets such as Schneider National Bulk Carriers Inc with 2 citations—the highest count in our database. This carrier operates large numbers of hazmat bulk vehicles, so the citation count reflects exposure rather than a pattern of negligence. Other carriers in our data show single citations each.
How severe is this compared to similar codes
This violation falls in the "Unsafe Driving" category. Peer codes in that category show far higher citation volumes. For example, code 392.2 (Operating a CMV while ill or fatigued) has recorded 1,208,164 citations with a 0.8% OOS rate. Code 392.2-SLLSR has 191,232 citations at 0.1% OOS. Code 392.2RG shows 96,652 citations at 0.1% OOS.
The contrast is stark: 392.10A4-RRC's 39 all-time citations place it far below these peer codes in raw volume, which reflects that most drivers and fleets do comply with railroad crossing protocols. However, the violation is not treated leniently—it simply occurs less often because most hazmat carriers have trained their personnel on this critical safety rule.
How to avoid it
Before every run with hazmat:
- Review your route for known railroad grade crossings. Use GPS or dispatch briefings to identify them in advance.
- Confirm you understand the full stop requirement: wheels must cease motion. Rolling stops do not satisfy the rule, even if you scan both directions.
- Verify that your vehicle's brakes are functioning normally during pre-trip inspection. A defective brake system increases the risk that you cannot stop smoothly or predictably at a crossing.
At the crossing itself:
- Begin slowing well in advance. Do not assume a crossing is safe because you see or hear nothing.
- Come to a complete stop before the crossing. Place the transmission in neutral and listen for train sounds for at least 10 seconds.
- Look both directions—do not rely solely on crossing gates, lights, or signals.
- Ensure the crossing is completely clear before proceeding at safe speed.
Fleet context:
- Our data shows that violations in this code sometimes co-occur with fatigue-related citations. If you are tired or ill, you are more likely to misjudge a crossing or fail to follow protocol. Report fatigue to dispatch and request a rest break.
- Peterbilt, Freightliner, Kenworth, and other cab-over or conventional chassis represent the majority of cited vehicles. If you operate one of these platforms, ensure your sightlines at railroad crossings are clear and that your mirrors are adjusted to eliminate blind spots.
