Q2 2026 carrier prints plus FMCSA/CVSA enforcement data test whether truckload capacity is structurally exiting; surfaces Montgomery v. Caribe Transport II (SCOTUS, 9-0, 2026-05-14) as a separate, dated forcing function on freight brokers.

Summary

The question this pass was aimed at — is truckload capacity structurally exiting or just cyclically tightening? — now has a first-party answer from a carrier CEO, which is what the existing hypothesis page was missing. Schneider National's CEO categorized the market as "driver-constrained" on the Q2 2026 call and quantified the remaining runway: "roughly half of the non-compliant capacity is left" to exit through next year. That is a supply statement, not a demand statement, and it is the discriminator the chain needed.

Underneath it sits a regulatory stack with hard dates: ELP out-of-service enforcement became permanent nationwide criteria on 2026-04-01, and the FMCSA non-domiciled CDL final rule took effect 2026-03-16, restricting eligibility to H-2A / H-2B / E-2 status. FMCSA's own estimate is that 97% of the ~200,000 non-domiciled CDL holders cannot satisfy the new requirements. J.B. Hunt — a carrier, publishing its own supply model — puts the combined removal at 5–12% of CDL holders (214,000–437,000 drivers) over two to three years and argues the industry "could reach peak active truck utilization as early as the fourth quarter of 2026."

Round 2 surfaced something the original question didn't anticipate and which is arguably the larger find: Montgomery v. Caribe Transport II, LLC, decided 9-0 on 2026-05-14 (Barrett, J.), holding that freight brokers can be sued under state law for negligently selecting unsafe motor carriers and that the FAAAA does not preempt those claims. This is a separate forcing function acting on the same industry through a different channel — brokerage economics and carrier eligibility rather than driver headcount — and it is undated-risk-free in a way most policy catalysts are not: a unanimous Supreme Court holding has no appeal path.

Findings

Theme 1 — The capacity exit is regulatory and dated, not cyclical

Three distinct enforcement actions, each with its own effective date:

English Language Proficiency (ELP). The Commercial Vehicle Safety Alliance added ELP to the North American Standard Out-of-Service Criteria effective 2025-06-25, and the April 1, 2026 edition lists it as a permanent, nationwide inspection standard (Truck Dispatch Experts, ELP enforcement 2026; TheTrucker.com, "Year of Enforcement"). Drivers failing ELP are placed out of service, which removes the truck, not just the driver, for the duration.
Non-domiciled CDL restriction. Effective 2026-03-16, the FMCSA final rule builds on the September 2025 emergency rule and limits non-domiciled CDL/CLP issuance, renewal, transfer and upgrade to holders of H-2A, H-2B or E-2 status (Jackson Lewis analysis; FMCSA newsroom release — release page returned HTTP 403 on fetch, cited via search extraction).
Visa revocations. Schneider's CEO stated "approximately 30,000 drivers had visas revoked, impacting cabotage capacity" (SNDR Q2 2026 transcript).

Sizing the removal. J.B. Hunt's published supply analysis gives the most explicit numbers available from an operator:

Non-domiciled CDL holders: 200,000, of whom 97% (~194,000) are estimated unable to meet the new requirements, over one to three years; that population is "about 5% of the 3.8 million CDLs registered in the U.S."
ELP: 19,000+ violations and 5,000+ out-of-service orders recorded June–September 2025, an annualized removal estimate of ~20,000 drivers.
Combined, J.B. Hunt states the reductions "are expected to remove between 5% to 12% of CDL holders (214,000–437,000 drivers) from the U.S. supply over the next two to three years," and that this is "building a wave of risks that could restrict capacity and increase costs for shippers." Under a full-impact scenario, "the industry could reach peak active truck utilization as early as the fourth quarter of 2026" (J.B. Hunt, Immigration Policy and Enforcement Impact on U.S. Commercial Driver Supply).

⚠ Source-interest note. J.B. Hunt is an asset-based carrier and intermodal operator; a tighter truckload market is favorable to it. The numbers it cites for the non-domiciled population trace to FMCSA, but the 5–12% aggregate and the Q4-2026 utilization-peak claim are J.B. Hunt's own model. Treat as an interested primary source, corroborated on the direction by Schneider (also interested) and on the rule mechanics by counsel commentary and CVSA/FMCSA dates (disinterested).

Theme 2 — The carrier prints: price is moving, and management attributes it to supply

Schneider National (SNDR), Q2 2026 (full transcript):

CEO Jim Filter: "We would now categorize the market as driver-constrained."
Filter: "Roughly half of the non-compliant capacity is left" to exit through next year — i.e. management believes the forcing function is half-spent, not spent.
Filter, on the enforcement stack: regulatory actions gaining traction include "non-domicile CDL usage, English language proficiency, illegal cabotage, entry-level driver training, and ELD tampering."
Filter: "The long-haul driver population in the U.S. sits well below long-term averages and near the lowest levels seen over the last decade."
Filter, on the transmission to price: supply attrition is "creating challenges in driver recruiting and retention, which is putting upward pressure on the cost of capacity"; and spot rates now "exceed contract rates at a level that has historically preceded more meaningful contract rate improvement."
CFO Darrell Campbell: Network revenue per truck per week up 16% year-over-year; Filter adds that network price renewals "accelerated with average price increases in the quarter of double digits."
Guidance raised: 2026 EPS to $0.90–$1.10 from $0.70–$1.00; net capex guidance reduced to $350–400M from $400–450M — a carrier raising earnings while cutting capex is not adding capacity into the tightness.
Intermodal contract renewals: "low single digits in the second quarter, now we're trending towards mid-single digits."
Admitted risks (falsifier material): Campbell — "We're anticipating the loss of a large dedicated customer, which will be more evident in the second half"; Filter — inflationary pressure "primarily due to higher energy costs" and "interest rates continue to weigh on end markets like housing."

Knight-Swift (KNX), Q2 2026 — no full free transcript located (Motley Fool 404, GuruFocus 403, Seeking Alpha paywalled), so figures below come from secondary reporting and should be treated as one step weaker than the Schneider quotes:

Truckload revenue ex-fuel and intersegment +2.8% YoY to $1.10B; revenue per loaded mile ex-fuel +5.5%; truckload segment operating income +96.3% to $89.1M (Yahoo Finance / Zacks, "Knight-Swift Q2 Earnings Beat Estimates on Truckload Margin Gains"; Commercial Carrier Journal).

The shape that matters: revenue per loaded mile up mid-single-digits while segment operating income roughly doubles is operating leverage on price, not volume. KNX truckload revenue grew 2.8% — volume is not the story.

Theme 3 — Montgomery v. Caribe Transport II: a second, independent forcing function

The holding. Decided 2026-05-14, No. 24-1238, unanimous, opinion by Justice Barrett (Kavanaugh concurring, joined by Alito): "A plaintiff's claim that a freight broker negligently hired a motor carrier to transport goods is not preempted by the Federal Aviation Administration Authorization Act" (Faegre Drinker; Justia, 608 U.S. ___ (2026); opinion PDF, supremecourt.gov).

The reasoning. The Court read the FAAAA safety exception as protecting claims that "concern" or "regard" motor vehicles; since requiring brokers to exercise ordinary care in carrier selection "concerns" the trucks used, negligent-hiring claims fall inside the exception. The Court acknowledged this creates an interpretive anomaly but preferred it to rewriting the statute (Faegre Drinker).

The facts (why this reaches C.H. Robinson specifically): Shawn Montgomery was severely injured when struck by a truck driven by Yosniel Varela-Mojena hauling for Caribe Transport II; C.H. Robinson Worldwide had brokered the shipment (Cornell LII; SCOTUSblog case page).

The economic transmission, per defense counsel writing to their broker clients (Benesch; Gordon Rees):

The early-exit defense is gone. Fact-specific negligence defenses are "less susceptible to early disposition on a motion to dismiss or motion for summary judgment, thereby driving up defense costs and settlement value" — cases that once resolved early now go through full discovery.
Insurance repricing follows mechanically. Higher defense costs and settlement values "naturally drive up insurance premiums for brokers."
Carrier vetting becomes a compliance function. Every broker now needs "a written policy or protocol… that governs how a broker onboards and monitors the ongoing eligibility of any given motor carrier", plus trained personnel and underwriter-approved selection criteria — "some underwriters may require a broker to adopt a particular carrier selection policy in order to be eligible for coverage."
The standard is undefined. On what constitutes reasonable care, Benesch is blunt: "The honest answer is that no one knows." Uncertainty of this kind is itself a cost — it pushes risk-averse behavior beyond what the rule strictly requires.

⚠ What the sources do NOT say. Neither Benesch nor Gordon Rees draws the market-structure conclusion. Benesch explicitly offers no analysis of capacity or consolidation effects, and does not state that brokers will shift toward larger or better-scored carriers. That inference is available and plausible — if underwriters gate coverage on carrier-selection policy, the marginal small carrier with a weak safety score becomes uninsurable to broker, hence unbookable — but it is unsourced as of this pass and must not be filed as an evidenced step.

Theme 4 — Why the two forcing functions compound rather than duplicate

They act on different populations through different mechanisms and would show up as double-counting only if conflated:

ELP / non-domiciled CDL removes drivers from the licensed pool. Effect: fewer trucks that can legally move, regardless of who books them.
Montgomery removes carriers from the brokered market by making a broker liable for selecting them. Effect: the same truck may remain legal to operate but become uneconomic for a broker to hire.

A carrier that survives the driver rules can still be squeezed out of broker freight by the liability rule; a carrier that brokers are willing to hire can still lose its drivers. The overlap is real but partial, and no source located in this pass attempts to net them.

Contradictions and open questions

No source nets the two forcing functions. J.B. Hunt's 5–12% covers driver removal only and pre-dates the market absorbing Montgomery. Nobody has published a combined capacity estimate.
The Montgomery → carrier-selection inference is unsourced. The insurance/litigation cost transmission is well-attested by counsel; the "therefore brokers concentrate freight with large, high-safety-score asset-based carriers" step is my inference from the underwriter-gating language, not a claim any fetched source makes. It needs a primary — a broker's own disclosure, a 10-Q risk factor, or an underwriter statement — before it can carry an evidence_status above open.
Interested-party density is high. The two richest sources (Schneider, J.B. Hunt) both benefit from the narrative they are describing. The disinterested corroboration is on rule mechanics and dates (CVSA, FMCSA, SCOTUS, defense counsel), not on magnitude. Magnitude therefore remains the weak axis.
KNX has no free full transcript this quarter, so its numbers are secondary. Werner's Q2 figures surfaced in search extraction with internally inconsistent growth rates (a "+24% top line" alongside "+36% TTS revenue") and are deliberately omitted rather than cited at that confidence.
Does the "half of non-compliant capacity remains" claim survive scrutiny? It is a single CEO's estimate of a quantity nobody measures directly, offered by someone whose pricing improves if it's true. It is the single most load-bearing and least corroborated number in this pass.
What happens to intermodal? Schneider's intermodal renewals moved low-single-digit → mid-single-digit, weaker than truckload's double-digit. If truckload price runs far enough, the intermodal conversion trigger the wiki already tracks should fire — but the spread implied here is narrowing more slowly than the truckload move alone would suggest.

Rounds run: 3 (full)

Sub-questions by round:

Round 1 (broad survey):

What did Knight-Swift, Werner and Schneider report in Q2 2026 on contract rates, revenue per loaded mile, and capacity?
What is the measured effect of ELP enforcement and non-domiciled CDL revocation on US driver supply, with dates and magnitudes?

Round 2 (drill-down):

What did the 2026 Supreme Court broker-liability ruling hold, and what does it do to freight capacity? — targeting the third leg of the question, which round 1 did not reach.
What are the FMCSA rule's effective date, eligible visa classes, and FMCSA's own non-qualification estimate? — targeting primary-source confirmation of the round-1 secondary reporting.

Round 3 (resolve remaining uncertainty):

What operational and economic consequences do practitioners argue follow from Montgomery? — targeting whether the ruling has a tradeable transmission or is merely legal news.
