FMCSA Regulations 2026 — Complete Compliance Guide

1. Hours of Service (HOS) Rules

Hours of Service regulations (49 CFR Part 395) set the maximum driving and on-duty time for commercial motor vehicle operators. These rules exist to prevent fatigue-related crashes, which the NTSB identifies as a contributing factor in roughly 13% of large truck crashes.

Current Limits for Property-Carrying Drivers

Split Sleeper Berth Provision

The 2020 HOS final rule expanded split sleeper flexibility. Drivers using a sleeper berth can split their 10-hour off-duty period into two periods: one period of at least 7 hours in the sleeper berth and one period of at least 2 hours either off duty or in the sleeper berth. Neither period counts against the 14-hour window when paired together (49 CFR 395.1(g)).

Key Exceptions

• Short-haul exception: Drivers operating within 150 air-miles who return to their reporting location within 14 hours are exempt from RODS (49 CFR 395.1(e)(1))
• Adverse driving conditions: Extends the driving window by 2 hours when encountering unexpected weather or road conditions (49 CFR 395.1(b)(1))
• Agricultural exemption: During planting and harvest seasons, drivers transporting agricultural commodities within 150 air-miles are exempt from HOS during that season

2. ELD Mandate

The ELD mandate (49 CFR Part 395, Subpart B) requires most commercial motor vehicle drivers to use certified Electronic Logging Devices to record their hours of service. The rule has been fully enforced since December 16, 2019, with no further phase-in periods.

Who Must Use an ELD

Any driver of a CMV required to keep Records of Duty Status (RODS) under 49 CFR 395.8 must use a registered ELD. This applies to interstate and intrastate operations if the state has adopted compatible regulations. The device must be registered on FMCSA's registered ELD list.

Exemptions (49 CFR 395.1(e))

• Drivers keeping RODS no more than 8 days in any 30-day period
• Drivers of vehicles manufactured before model year 2000
• Driveaway-towaway operations (vehicle is the commodity)
• Short-haul drivers operating under 49 CFR 395.1(e)(1)

ELD Requirements During Inspection

During a roadside inspection, drivers must present their ELD records for the current 24-hour period and the previous 7 consecutive days. Acceptable transfer methods include Bluetooth, USB, email, or printout. If the ELD malfunctions, drivers have 8 days to get it repaired and must keep paper logs in the interim (49 CFR 395.34(a)).

3. Drug & Alcohol Clearinghouse

The FMCSA Drug & Alcohol Clearinghouse (49 CFR Part 382, Subpart G) is a secure online database that tracks CDL driver drug and alcohol violations. Since January 6, 2020, employers must use the Clearinghouse for pre-employment queries and annual checks. Since November 18, 2024 (Clearinghouse II), state driver licensing agencies are also required to query the Clearinghouse before issuing, renewing, or transferring CDLs.

Registration Requirements

• Employers/carriers: Must register at clearinghouse.fmcsa.dot.gov and designate a Clearinghouse administrator
• CDL drivers: Must register to respond to consent requests and view their own records
• Medical Review Officers (MROs): Must report verified positive tests, refusals, and return-to-duty results
• Substance Abuse Professionals (SAPs): Must report initial assessments and follow-up evaluations

Query Types and Costs

Clearinghouse II (Effective November 2024)

Clearinghouse II closed a major loophole. Previously, a driver with a drug or alcohol violation in one state could simply obtain a CDL in another state. Now state DMVs must query the Clearinghouse before any CDL issuance, renewal, upgrade, or transfer. Drivers with unresolved violations cannot hold a valid CDL until they complete the return-to-duty process.

4. Entry-Level Driver Training (ELDT)

Since February 7, 2022, all entry-level CDL applicants must complete training from a provider listed on FMCSA's Training Provider Registry (TPR) before taking their CDL skills test (49 CFR Part 380, Subpart F). This replaced the previous patchwork of state requirements with a uniform federal standard.

Who Must Complete ELDT

• First-time Class A CDL applicants
• First-time Class B CDL applicants
• Drivers upgrading from Class B to Class A
• Drivers adding a hazmat (H), passenger (P), or school bus (S) endorsement for the first time

Training Requirements

ELDT includes both theory (classroom/online) and behind-the-wheel (BTW) instruction. There is no minimum hour requirement set by FMCSA — the training provider determines proficiency using the prescribed curriculum. However, the training must cover all topics in the ELDT curriculum published in 49 CFR Part 380, Appendix A through E.

Training Provider Registry (TPR)

Training providers must self-certify that they meet FMCSA curriculum standards and register on the TPR portal. Upon completion, the provider transmits the training results to the TPR, which the state licensing agency verifies before administering the skills test.

Explore training programs in our CDL training guide.

5. CDL Requirements

Commercial Driver's License requirements are governed by 49 CFR Part 383. Any driver operating a CMV as defined by federal standards must hold the appropriate CDL class and endorsements.

CDL Classes

Endorsements

• T — Double/Triple Trailers: Knowledge test only
• P — Passenger: Knowledge and skills test
• N — Tank Vehicle: Knowledge test only
• H — Hazmat: Knowledge test + TSA background check (renewed every 5 years)
• X — Tanker + Hazmat: Combination of N and H
• S — School Bus: Knowledge and skills test

Medical Certificate (DOT Physical)

All CDL holders operating in interstate commerce must maintain a valid Medical Examiner's Certificate (49 CFR Part 391, Subpart E). The standard certificate is valid for up to 24 months. Drivers with certain conditions (insulin-treated diabetes, hypertension requiring medication) may receive certificates valid for 12 months or less. The examination must be performed by a medical examiner listed on FMCSA's National Registry.

6. Insurance Minimums

Federal insurance requirements for motor carriers are specified in 49 CFR Part 387. These are minimums — most brokers and shippers require carriers to carry higher limits, and industry practice has moved well beyond the federally required floors.

Liability Insurance (49 CFR 387.9)

Industry Reality

While federal minimums for general freight are $750,000, most brokers require $1,000,000 in auto liability. Cargo insurance is not federally mandated for most carriers, but shippers universally require it — typically $100,000 minimum, with $250,000 common for high-value freight. Many large shippers (Amazon, Walmart, Target) require $1,000,000 auto liability plus $100,000 cargo.

7. Vehicle Inspection Requirements

Vehicle inspection requirements fall under 49 CFR Parts 392 and 396. They include three layers: driver pre-trip/post-trip inspections, periodic (annual) inspections, and roadside inspections conducted by law enforcement.

Pre-Trip and Post-Trip Inspections (49 CFR 396.13)

Drivers must conduct a pre-trip inspection before operating a CMV and a post-trip inspection at the end of each day's work. The pre-trip must verify the condition of: brakes, coupling devices, lights, tires, horn, windshield wipers, mirrors, emergency equipment, and any items listed on the previous driver's DVIR (Driver Vehicle Inspection Report). Post-trip DVIRs must document any deficiencies discovered during operation.

Annual Inspections (49 CFR 396.17)

Every CMV must pass a comprehensive annual inspection covering all 14 inspection categories listed in Appendix G to 49 CFR Part 396. The inspection must be performed by a qualified inspector, and a copy of the inspection report must be kept on the vehicle or made available within 24 hours. The annual inspection sticker must be displayed on the vehicle.

Roadside Inspections (CVSA Levels)

• Level I — Full: Complete driver and vehicle examination (37-point North American Standard)
• Level II — Walk-Around: Driver examination plus vehicle walk-around (no under-vehicle)
• Level III — Driver Only: Credentials, HOS, seatbelt, and visible hazmat compliance
• Level IV — Special: One-time examination of a specific item
• Level V — Vehicle Only: No driver present; conducted at a facility

8. Hazmat Regulations

Hazardous materials transportation is jointly regulated by FMCSA (driver qualifications, safety) and PHMSA (packaging, classification, placarding) under 49 CFR Parts 171-180 and Part 383. Violations carry the highest penalties in trucking — up to $96,624 per violation and criminal prosecution for knowing violations.

Hazmat Endorsement (H Endorsement)

Any driver transporting hazardous materials requiring placards must hold an H endorsement on their CDL. Requirements include passing a hazmat knowledge test, completing a TSA security threat assessment (fingerprinting, background check, fee of approximately $86.50), and ELDT hazmat training from a TPR-listed provider (if adding the endorsement for the first time after February 2022). The endorsement and TSA clearance must be renewed every 5 years.

Placarding Requirements (49 CFR 172, Subpart F)

Vehicles must be placarded on all four sides when carrying any quantity of Table 1 materials (explosives, poison gas, water-reactive) or 1,001+ lbs aggregate gross weight of Table 2 materials (flammable liquids, oxidizers, corrosives). Mixed loads exceeding 1,001 lbs aggregate may use DANGEROUS placards. The shipper provides placards unless the carrier has an agreement to provide their own.

Routing and Parking Restrictions

• Hazmat vehicles must follow designated routes when established by state or local authorities (49 CFR 397.67)
• Parking is prohibited within 5 feet of a traveled roadway (49 CFR 397.7)
• Vehicles carrying Division 1.1, 1.2, or 1.3 explosives cannot be left unattended on public property (49 CFR 397.5)
• Fueling with the engine running is prohibited for hazmat vehicles (49 CFR 397.13)

9. New and Proposed Regulations for 2026

Several significant rulemakings are in various stages of the regulatory process. Here is the current status of the most impactful proposed rules.

Speed Limiter Rule

FMCSA and NHTSA jointly proposed requiring speed limiting devices on CMVs with a gross vehicle weight rating of 26,001+ lbs. The Supplemental Notice of Proposed Rulemaking (SNPRM) proposes a maximum speed between 60, 65, or 68 mph (final limit to be determined). The rule would apply to vehicles manufactured after a set model year and equipped with ECMs capable of speed governance. As of March 2026, the rule is in the final rulemaking stage but has not been published as a final rule.

Hair Follicle Drug Testing

FMCSA has been directed by Congress (under the FAST Act, Section 5402) to allow hair follicle testing as an acceptable alternative to urinalysis for pre-employment DOT drug tests. Hair testing detects substance use over a 90-day window compared to the 2-3 day window for urine. HHS published guidelines for federal workplace hair testing. Once FMCSA publishes its final rule, carriers will be able to use hair testing to satisfy pre-employment requirements, though urinalysis will still be required for random, post-accident, reasonable suspicion, and return-to-duty tests.

Automatic Emergency Braking (AEB)

NHTSA published a final rule requiring AEB systems on heavy vehicles (Class 7 and 8 trucks). The rule phases in over several years beginning with new vehicle manufacturing. AEB systems must be able to detect and respond to a lead vehicle and, in later phases, pedestrians. This applies to manufacturers, not retroactively to existing vehicles, but carriers purchasing new trucks should budget for AEB-equipped models.

Broker Transparency Rule

FMCSA has proposed amendments to 49 CFR Part 371 that would require freight brokers to provide carriers with electronic access to transaction records within 48 hours of delivery, rather than the current requirement to make records available upon request. This aims to increase rate transparency and reduce disputes over broker commissions.
