What is the minimum requirement for peripheral vision?

1. 50 degrees

2. 60 degrees

3. 70 degrees

4. 80 degrees

The correct answer is: 70 degrees

Peripheral vision, also known as side vision, is crucial for safe driving as it allows an individual to detect objects or movement outside of their direct line of sight. The minimum requirement for peripheral vision is set at 70 degrees from the center of the visual field. This standard ensures that individuals have adequate visibility to notice approaching pedestrians, vehicles, and other potential hazards that may not be directly in front of them while they are focusing ahead. Achieving this level of peripheral awareness is important for maintaining overall situational awareness while driving, as it allows the driver to respond effectively to various stimuli and avoid accidents. A wider peripheral range aids in enhancing safety, but the minimum standard is established at 70 degrees to ensure that drivers can operate vehicles safely and effectively.
