What is the required distant visual acuity to drive a CMV and obtain a CDL?

• A. 20/30
• B. 20/40
• C. 20/50
• D. 20/20

Answer: (B)

To drive a Commercial Motor Vehicle (CMV) and obtain a Commercial Driver's License (CDL), the standard for distant visual acuity is indeed 20/40. This means that a driver must be able to clearly see at 20 feet what a person with normal vision can see at 40 feet. This level of visual acuity is crucial for safely operating large vehicles, as it ensures drivers can adequately see road signs, obstacles, and other vehicles at a safe distance, which is essential for making informed driving decisions and maintaining proper reaction times. While options like 20/30 and 20/20 indicate better visual acuity, 20/40 is the minimum requirement set by regulations, balancing the need for safety while allowing a broader range of individuals to qualify for a CDL. Therefore, individuals who meet the 20/40 visual acuity standard can perform the necessary visual tasks without significant impairment while driving a CMV.
