Because central vision covers only a small portion of the field, drivers should rely on scanning to gather information from where?

• A. The center
• B. The instrument panel
• C. The periphery
• D. The rearview mirrors

Answer: (C)

Central vision provides sharp detail in a small area, so you must rely on scanning to take in what’s around you. By using your eyes and head to survey the periphery—far to the left and right, ahead and to the sides—you can detect hazards that aren’t in your direct line of sight, such as a car signaling to merge, a pedestrian stepping into the roadway, or bikes and motorcycles approaching from the side. This wide-field awareness is essential for anticipating changes in traffic and staying safe.

Focusing on the instrument panel would keep you inside the car and miss what's happening on the road, while relying on rearview mirrors only covers what’s behind you. The periphery, by contrast, gives you the broad sense of motion and potential conflicts you need to respond to in time.
