I wonder what happened to the suggestion that all drivers of trucks from Mexico or ANYWHERE - be able to read and speak ENGLISH..and pass the tests for an American Commercial Truck driving license in ENGLISH?
It IS an FMCSA/DOT requirement.
49 CFR 391.11(b)(2) of the FMCSRs state...
This provision requires that drivers of CMVs operating in interstate commerce be able to ``read and speak the English language sufficiently to converse with the general public, understand highway traffic signs and signals, respond to official inquiries, and make entries on reports and records.”
