FMCSA Railroad Grade Crossings 2026: Comment Window Closes April 27
FMCSA is reconsidering the rule requiring CMV drivers to stop at every railroad grade crossing. A proposed exception for crossings with inactive warning devices is open for comment through April 27. What it means for your fleet.
FMCSA Railroad Grade Crossings 2026: Comment Window Closes April 27
On March 27, 2026, FMCSA published a Notice of Data Availability (NODA) on a proposed exception to one of the most familiar requirements in the Federal Motor Carrier Safety Regulations: the rule that certain CMV drivers must stop at every railroad grade crossing. The proposed exception would allow drivers to proceed without a full stop when the crossing is equipped with an active warning device that is not currently in an activated state. The comment window closes April 27, 2026. This is not a final rule, and it is not even a full Notice of Proposed Rulemaking — it is FMCSA telling the public that it has information under consideration and is inviting input before any further regulatory action. But the change, if it advances, would affect driver training, operational SOPs, and dispatcher guidance for fleets operating vehicles subject to 49 CFR 392.10. Dot compliance managers should understand what is on the table and, if useful to the record, file a comment by Sunday.
The current rule
Under 49 CFR 392.10, the driver of certain commercial motor vehicles — including buses, vehicles carrying chlorine, cargo tank motor vehicles used for hazardous materials, and vehicles carrying any amount of hazardous substance or waste identified in the regulation — must stop at every railroad grade crossing before driving across the tracks. The stop must occur between 15 and 50 feet from the nearest rail. The driver must listen and look in each direction for an approaching train and must not shift gears while crossing. The rule applies whether or not the crossing has active warning devices such as flashing lights, bells, or gates. The requirement exists because these categories of vehicles and cargo carry the highest consequence-of-impact profiles; even when warning systems are present and working, the current rule assumes a belt-and-suspenders posture.
Section 392.10 has been on the books in various forms for decades. It intersects with 49 CFR 392.11 (which describes the broader grade-crossing duties for vehicles not covered by 392.10) and with state-level railroad crossing rules that can be stricter. Fleet compliance programs for HazMat operations, passenger motor carriers, and tank motor carriers teach drivers the section 392.10 duties as a core element of CDL-level training. Violations show up in roadside inspections and contribute to CSA's Unsafe Driving BASIC.
The proposed exception in plain English
The NODA outlines a proposed exception. When a railroad grade crossing is equipped with an active warning device — flashing lights, a bell, a gate, or a combination — and that device is not currently in an activated state (meaning no train is approaching and the warning system is indicating an "all clear"), the driver covered by section 392.10 would be permitted to proceed through the crossing without the mandatory stop. The driver would still be required to reduce speed, look in each direction for an approaching train, and maintain control of the vehicle through the crossing. The full stop at 15–50 feet would no longer be required.
FMCSA is framing the proposal as recognition that modern active warning devices at many grade crossings provide real-time information about train presence that the original rule could not assume. The NODA is the Agency's way of surfacing data it has been developing and inviting industry, safety groups, state partners, and the public to push back or refine before FMCSA decides whether to issue a formal Notice of Proposed Rulemaking. A NODA is an early signal. It is not the rule itself.
Who this affects — fleets, drivers, insurers
Four categories of fleet operations are directly covered by section 392.10 and would be most affected if the exception advances. School buses and other passenger-carrying CMVs would see revised expectations at grade crossings; driver training curricula would need substantial update. HazMat tank motor carriers — fuel, chlorine, anhydrous ammonia, and other placardable loads — would gain operational efficiency from not stopping at every crossing on a dedicated route, at the cost of losing the belt-and-suspenders stop. HazMat general freight carriers handling the specified substance categories would be in the same position. Any fleet that operates mixed-purpose vehicles whose compliance posture depends on cargo type on a given day would need updated dispatcher guidance so drivers know when the exception applies and when it does not.
Beyond the directly-regulated fleets, safety managers at fleets not currently subject to section 392.10 should still pay attention. The regulatory trend signaled by this NODA — relying on active warning device state to modify a prescriptive stopping requirement — could migrate into adjacent rules over time. Insurers writing primary commercial auto liability for HazMat and passenger-carrying fleets will want to understand how the exception changes claim profiles and may adjust underwriting questions. FMCSA would likely need to update roadside inspection guidance, enforcement procedures, and related compliance materials if the exception ultimately becomes part of the regulation.
What to do and by when
- By April 27, 2026 (Sunday). If your fleet has operational data, training curriculum expertise, or safety-outcome insight that is relevant, file a comment at regulations.gov under Docket FMCSA-2021-0050. Useful comments for a NODA are more about data and operational reality than legal theory. Examples: crash-rate data from specific corridor operations, driver training hours currently dedicated to section 392.10 duties, dispatcher SOP documentation, insurance loss ratios by crossing type.
- Within the next two weeks. Map your current exposure. Count the CMVs in your fleet subject to section 392.10 by cargo type and route. Identify routes that cross active railroad grade crossings. The output is a baseline you can use to assess impact if and when the exception advances.
- Within the next 60 days. Review your driver training curriculum on grade crossing duties. Do not change the curriculum yet — the exception has not advanced past NODA. But confirm you have a current, documented curriculum, because if the rule changes you will need to show retraining records to both inspectors and insurers.
- Monitor the Federal Register. If FMCSA issues a formal NPRM on this topic after reviewing NODA comments, there will be another comment window. That is the more consequential filing. Stay on the docket.
Driver training implications
If the exception advances, driver training for HazMat-endorsed and passenger-carrying CDL drivers will need two specific updates. First, trainees will need to learn the conditions under which the exception applies: active warning device present, device not in activated state, driver maintains reduced speed and look-listen duty. Second, trainees will need to learn when the exception does not apply: passive-crossing (no active warning device), device in activated state, device inoperative, unclear device state due to weather or visibility. The distinction is more nuanced than the current flat "always stop" rule, which is exactly why the regulatory community has handled grade crossings with a bright-line rule for so long. Fleets should expect longer training modules, more scenario-based testing, and more ongoing refreshers if the exception becomes law.
For fleets currently using Foley's driver qualification support, the training-record plumbing already exists — what changes is the content of the training, not the documentation workflow. For fleets that rely on CDL schools or third-party training providers, ask how they plan to update curriculum if the rule advances. The transition period between a new rule and updated roadside-inspection guidance is where compliance risk spikes; plan to retrain before the effective date, not after.
How Foley helps
Foley supports motor carriers on driver qualification files, CDL-level compliance, and ongoing regulatory monitoring for the kind of rule changes that emerge from NODA-stage proposals. When a regulatory change touches driver training curricula, the downstream effect on DQ files, annual driver reviews, and audit-readiness is where compliance programs typically lose ground. Foley's compliance team can walk through how a proposed section 392.10 change would map to your existing training and documentation.

Frequently asked questions
Is section 392.10 changing now?
No. The NODA is an early regulatory signal, not a rule change. Section 392.10 continues to require covered drivers to stop at every railroad grade crossing until and unless FMCSA issues a final rule changing it.
Which of my drivers are subject to section 392.10 today?
Drivers of buses, vehicles carrying chlorine, cargo tank motor vehicles used for hazardous materials, and vehicles carrying hazardous substances or wastes as identified in the regulation. Check the specific list in 49 CFR 392.10 for the full enumeration. A driver with a mixed schedule may be covered on some trips and not on others depending on cargo.
What happens after April 27?
FMCSA reviews comments and decides whether to advance a formal Notice of Proposed Rulemaking. A NODA can also end without further action if the Agency decides the data does not support a rule change. There is no guaranteed next step and no guaranteed timeline.
Does state law override federal rule changes here?
If your fleet operates in states with additional railroad grade crossing requirements or compatibility provisions tied to state CMV safety enforcement, review how those rules interact with any future federal change to section 392.10.
