In the US, the issue of English language proficiency for commercial drivers has resurfaced. The Federal Motor Carrier Safety Administration (FMCSA) announced the return of strict enforcement of requirements that have formally existed for many years but were not always practically applied.
Starting in the summer of 2025, lack of English proficiency could lead not just to a warning but to an immediate out-of-service order — a ban on continuing the trip until the violation is corrected.
The requirement for English language proficiency has long been enshrined in federal regulations — in regulation 49 CFR §391.11(b)(2). However, in recent years, inspectors have rarely used it as a basis for stopping a driver.
Now FMCSA has officially returned to actively enforcing the rule. As explained in the agency's clarification, English language proficiency is considered a safety factor:
“The driver must be able to effectively communicate with inspectors and understand road signs to ensure safety on public roads.”
A detailed analysis of the new rules is published in industry media, including in the article TruckingInfo.
During a roadside inspection, the inspector assesses English language proficiency without translators or apps. The check includes:
- oral communication with the driver in English
- ability to understand questions and instructions
- recognition of standard road signs and messages
If the driver fails the check, the inspector has the right to declare them unable to continue driving. This means downtime, cargo delays, and additional costs for the carrier.
FMCSA emphasizes that the use of translators, cards, or mobile apps during the inspection is unacceptable. This is also stated in the official clarifications of the agency on the FMCSA website.
For drivers, the consequences are clear: even with extensive experience and a clean inspection history, weak English now becomes a real risk.
For companies, the situation is even more complicated:
- out-of-service affects CSA ratings
- potential delivery delays
- increased risk of fines and inspections
Legal and compliance experts note that carriers should preemptively check drivers' language readiness. As noted by J.J. Keller:
“Carriers are responsible for ensuring their drivers meet all qualification requirements, including English language proficiency.”
A detailed legal analysis of the requirement is available in the J.J. Keller analysis.
Although the rule is not formally new, the approach to its enforcement has changed. Therefore, drivers and companies should perceive the situation as a new reality, not a temporary campaign.
In practice, this means:
- preparing drivers for oral communication with inspectors
- checking understanding of road signs and formulations
- documenting compliance with requirements in the driver qualification file
FMCSA makes it clear: English language proficiency is not a formality but an element of road safety. In the context of increased control, language proficiency becomes as critically important a skill as compliance with HOS or having a medical certificate.
For the industry, this is a signal to adapt in advance, not to wait for the first out-of-service at scales or roadside inspection.
