FMCSA Renews Rail HOS Exemption: What Drivers Need to Know

FMCSA Renews Rail HOS Exemption: What It Means for CDL Drivers

The Federal Motor Carrier Safety Administration (FMCSA) has announced a provisional four-month renewal of the Hours of Service (HOS) exemption previously granted to the Association of American Railroads (AAR) and the American Short Line and Regional Railroad Association (ASLRRA). This exemption, originally granted to allow railroad employees who also perform truck driving duties to operate beyond the standard 14-hour on-duty limit, has been a point of contention and confusion for many CDL drivers.

Background of the Exemption

In 2020, the AAR and ASLRRA petitioned for an exemption from the HOS rules that prohibit driving after the 14th hour from the start of the workday. The exemption applies to drivers who are primarily employed by railroads and who drive commercial motor vehicles (CMVs) as part of their rail duties—such as moving equipment or materials between rail yards. The FMCSA granted a five-year exemption in 2021, which expired in June 2026. The renewal extends the exemption for an additional four months while the agency considers a longer-term decision.

Why This Matters to CDL Drivers

For professional truck drivers, HOS rules are the backbone of safety and fair competition. The 14-hour rule is designed to prevent fatigue-related accidents. When exemptions are granted, it can create an uneven playing field. Rail-affiliated drivers may be allowed to work longer shifts, potentially leading to fatigue or safety concerns that affect all road users.

According to FMCSA data, the exemption covers approximately 1,200 drivers across 30 railroads. While this is a small fraction of the 3.5 million CDL holders in the U.S., it sets a precedent that could influence future exemption requests. As we discussed in our earlier post on CDL Exemption Request Fuels DACA Debate, exemptions often spark broader regulatory discussions.

The Four-Month Renewal: What's Next?

The FMCSA's decision to renew for only four months—rather than the full five years requested—indicates the agency is taking a cautious approach. During this period, the AAR and ASLRRA must continue to meet reporting requirements, including data on accidents, hours worked, and driver fatigue. The agency will use this data to evaluate whether the exemption should be made permanent, modified, or revoked.

Impact on Safety and Compliance

Critics argue that any HOS exemption undermines safety. The Owner-Operator Independent Drivers Association (OOIDA) has consistently opposed such exemptions, stating that they create a two-tiered system where some drivers are held to different standards. On the other hand, railroads argue that their operations are unique—short-haul trips, low traffic density, and specialized equipment—and that rigid HOS rules can cause operational inefficiencies.

For CDL drivers, the key takeaway is vigilance. If you share the road with rail-affiliated CMVs, be aware that they may have different HOS limits. Always maintain safe following distances and report any unsafe driving to FMCSA.

How This Fits into Broader Regulatory Trends

This exemption renewal comes amid a flurry of regulatory activity. For example, the EPA Doubles Down on California Emissions Crackdown shows how federal and state agencies are tightening rules on trucking. Meanwhile, Trucker Restroom Access: What the Rumors Really Mean highlights ongoing driver welfare concerns. The HOS exemption is just one piece of a larger puzzle.

What Drivers Should Do

• Stay Informed: Monitor FMCSA announcements on exemption renewals. The four-month window means a decision could come as early as October 2026.
• Log Your Hours Accurately: Whether you use ELDs or paper logs, ensure your records are precise. Exemptions for others don't change your obligations.
• Advocate for Fairness: Join industry groups like OOIDA to voice your opinion on exemptions that affect competition and safety.

For Carriers: Ensure Compliance

If your fleet operates near rail yards or contracts with railroads, review your HOS policies. The exemption does not apply to typical over-the-road trucking. Ensure your drivers understand that the 14-hour rule still applies to them.

FAQ

Q: Does the AAR HOS exemption apply to all CDL drivers?

A: No. It only applies to drivers employed by member railroads of the AAR or ASLRRA who are performing rail-related duties. Standard CDL drivers must still follow the 14-hour rule.

Q: How long is the exemption renewal valid?

A: The FMCSA renewed the exemption provisionally for four months, starting June 24, 2026. A final decision on a longer-term extension is expected by October 2026.

Q: What happens if a rail-affiliated driver violates HOS under the exemption?

A: The exemption requires railroads to report any accidents or violations. FMCSA can revoke the exemption if safety data shows increased risk. Drivers should still follow their employer's safety policies.
