In order for a driver to be certified, which of the following visual metrics must they meet?

For a driver to be certified, maintaining a horizontal field of vision is critical for safe driving, as it allows them to be aware of their surroundings and react accordingly. The requirement for a horizontal field of vision of at least 70° measured in each eye ensures that the driver has enough peripheral awareness to detect obstacles and other vehicles. This metric helps to confirm that the driver can adequately perceive their environment, which is essential for making quick decisions while navigating.

The other visual metrics presented do not meet the comprehensive safety standards required for certification. Binocular acuity and distant visual acuity are important but are not sufficient on their own without a healthy field of vision. The 70° field of vision standard is specifically geared towards enhancing the driver's ability to maintain a safe operation of their vehicle on the road, reinforcing the importance of having broad visual awareness from both eyes.
