FMCSA published a thick stack of rules and guidance through 2025 and into 2026. Most don't affect daily operations. Three do. Here's what changed, what action it requires, and the deadline.

1. Drug & Alcohol Clearinghouse — tightened query rules

Effective: January 6, 2026

What changed: The pre-employment full query is now mandatory for any CDL hire — including owner-operators bringing on a single driver and lease-on operations. Previously, the limited annual query was acceptable for some employment situations. That gap closed.

Action required:

  • Employer must request driver consent in writing.
  • Driver must register with the Clearinghouse and grant consent.
  • Employer must run a full query before the driver performs any safety-sensitive function.
  • Annual query thereafter is now required for every CDL driver, no exceptions.

Cost: Queries run $1.25 (limited) and $10 (full) per driver. Annual cost for a single-truck owner-op who hires one driver: $11.25/year. For a 10-truck fleet hiring three drivers a year: ~$160/year.

Penalty for non-compliance: Up to $5,833 per offense, plus the driver can be barred from operating until cured.

2. CSA Safety Measurement System — reweighting

Effective: Phased rollout through Q2 2026

What changed: FMCSA reweighted how violations roll into your BASIC scores in the Safety Measurement System (SMS). The Unsafe Driving and Hours of Service BASICs now weight roadside violations more heavily; Vehicle Maintenance reduced weight on minor maintenance violations (e.g., a single bad lamp).

What it means in practice:

  • A speeding ticket or HOS log violation now hurts your CSA score harder.
  • A minor maintenance defect at roadside hurts less.
  • Net effect for most carriers: small, but if your weak BASIC was Unsafe Driving, it just got worse.

Action required: Pull your SMS percentile from the FMCSA Safety Measurement System portal. If any BASIC is above the 65th percentile alert threshold, you should:

  • Review recent inspection violations
  • Challenge any incorrect violations through DataQs within 30 days
  • Address root causes (driver training, equipment maintenance) before the next inspection cycle

3. ELDT — Entry-Level Driver Training enforcement

Effective: Already in effect; enforcement tightened in 2026

What changed: Any new CDL applicant after February 7, 2022 must complete training from a Training Provider Registry (TPR)-listed provider before taking the CDL skills test. In 2026, FMCSA started auditing TPR providers more aggressively and removing non-compliant ones.

What it means for you:

  • If you train new drivers in-house, verify your operation is registered on the TPR. Hiring a driver who took ELDT from an unregistered provider invalidates their CDL upgrade.
  • If you hire newly-CDL'd drivers, verify their training provider is currently TPR-registered (the registry is public).

What didn't change but everyone asks about

Hours of Service. No 2026 changes. Sleeper berth flexibility, 11/14/70-hour rules, and the 30-minute break rule all unchanged from the 2020 revisions.

ELD mandate. No new mandate. Pre-2000 model engines remain exempt. Short-haul exemption (150 air-mile, 14 consecutive hour limit) remains.

Mexican carrier reciprocity. Still pending political resolution. Don't plan around it.

Action checklist for owner-operators

If you're running your own MC authority:

  • Confirm your Clearinghouse account is active and consent records are on file for any drivers you've hired.
  • Pull your CSA SMS percentile this month and address anything above 65.
  • If you're considering getting your own MC authority, the process hasn't changed — but the Clearinghouse and CSA setup steps now matter from day one.
  • Confirm any third-party training providers you use (or recommend to drivers) are still TPR-registered.

For owner-operators who don't yet have their MC authority and are weighing the move, we walk through the full setup at truckers.finance/mc-authority — including the BOC-3 filing, insurance requirements, and the IFTA/2290 follow-on filings most new authorities forget.
