DOT Certification Practice Exam

The Federal Vision Examination Program is specifically mentioned in the Code of Federal Regulations under the correct citation, which is 49 CFR 391.41(b)(10). This citation outlines the medical standards required for individuals operating commercial motor vehicles and includes specific requirements for vision testing as part of the medical examination process.

The reference to 49 CFR indicates the title number pertaining to transportation regulations, while "391" specifies the section that governs qualifications for drivers. By identifying "41(b)(10)", it denotes the specific regulatory requirement regarding vision standards for drivers, thereby providing clarity on this important aspect of commercial vehicle operation.

This citation is critical for ensuring that drivers meet the necessary vision standards for safety on the roads. The other choices, although similar in format, reference incorrect parts of the regulations that do not pertain to the Federal Vision Examination Program, which is why they do not provide the correct source for the information sought.
