Lesson 4 - Chapter 7 Questions

Vision is the 5 degree cone representing only 3% of a driver's total visual field.

• Central

• Tunnel

• Fringe

• Peripheral

The distance ahead that you search as you drive is your:

• Targeting scope

• Visual scope

• Targeting lead

• Visual lead

Drivers should search at least (a)   seconds ahead

• 3 to 4

• 9 to 10

• 12 to 15

• 20 to 30

Drivers should maintain a visual control zone of at least (a)   seconds ahead

• 3 to 4

• 9 to 10

• 12 to 15

• 20 to 30

To effectively search the total traffic scene, drivers should monitor the area (a)   of the vehicle.

• To the read

• To the sides

• To the front

• All of the above

1) Define central vision: Central vision is the ability to see objects clearly in the middle of the visual field.

• It is the ability to see objects clearly in the middle of the visual field.

• It refers to the peripheral vision used for detecting motion.

• It is the low-light vision used during night time.

• It describes the vision in the far periphery of the visual field.

2) Define peripheral vision:

• The ability to see objects outside the direct line of sight

• The ability to see objects clearly in the center only

• Concentrating solely on objects near the focus point

• Vision in the dark without light

3) Describe how to perform ground viewing and explain how this technique can reduce driving risk:

• It involves positioning oneself to monitor potential hazards on the ground, thereby offering advanced warning and reducing the likelihood of accidents.

• It is a method to eliminate all risks associated with driving.

• It only involves checking the mirrors while driving.

• It is unrelated to driving safety measures.

4) Define Fringe vision:

• It refers to the vague and unsharp peripheral vision where objects appear only as blurry shapes.

• It denotes the clear, focused vision in the center of our visual field.

• It is the ability to perceive color differences accurately in the periphery.

• It is the complete absence of peripheral vision.
