On April 28, 2025, the U.S. government issued an executive order reinforcing a long-standing regulation by the Federal Motor Carrier Safety Administration (FMCSA) under 49 CFR § 391.11(b)(2). This directive mandates immediate and strict nationwide enforcement of English language proficiency requirements for all CDL (Commercial Driver’s License) holders operating in the United States.
This major enforcement shift could have a significant impact on carriers and drivers alike. Here’s what you need to know:
What are the FMCSA English proficiency requirements for commercial drivers?
According to 49 CFR § 391.11(b)(2), every CDL driver must be able to communicate in English well enough to:
- Read and understand road signs, traffic signals, and official postings written in English
- Communicate effectively with DOT officers and law enforcement
- Respond appropriately to official inquiries
- Complete necessary documentation, including inspection reports, driver logs, and all other required forms
If a driver fails to demonstrate proficiency in any of these areas during a roadside inspection, they may be deemed not qualified to operate a commercial vehicle and can be placed Out of Service immediately.

What This Means for Carriers and CDL Drivers
The stricter enforcement of this rule carries serious implications:
- Increased Inspections: DOT officers and inspectors will now more closely evaluate drivers’ English communication abilities during stops.
- Immediate Out-of-Service Orders: Drivers unable to meet the English proficiency standards can be removed from service on the spot.
- Operational Risks: Non-compliance could lead to fines, shipment delays, and operational disruptions that could harm your business reputation and profitability.
States Already Increasing Compliance
Some states have already ramped up enforcement following the executive order, including:
- Illinois
- Kentucky
- Tennessee
Carriers operating in these states should prepare for higher inspection rates and stricter scrutiny.
