Top 2 Vision & Perception
Vision to read & identify distinct objects is called FOCAL vision and is usually about 3-5 degrees
Vision needed to judge depth & position is called CENTRAL vision and is between 30 -36 degrees
Peripheral vision is 175-185 degrees wide & is used to detect motion and color changes
![Page 8: Module 3 2009](https://reader033.fdocuments.in/reader033/viewer/2022061220/54bb2e674a79593a118b457f/html5/thumbnails/8.jpg)

4. Vision
If a vehicle is approaching from the side, detect it’s motion using peripheral vision. Identify the type of vehicle using central vision. Finally, determine the make & model using focal vision
![Page 10: Module 3 2009](https://reader033.fdocuments.in/reader033/viewer/2022061220/54bb2e674a79593a118b457f/html5/thumbnails/10.jpg)
5. Good visual habits involve:
Involve establishing a path of travel with a targeted area 20 seconds ahead of the vehicle
This is called a VISUAL LEAD
![Page 11: Module 3 2009](https://reader033.fdocuments.in/reader033/viewer/2022061220/54bb2e674a79593a118b457f/html5/thumbnails/11.jpg)
6. When you are unable to see your targeted area, you should
Slow down!
Reduce speed
![Page 12: Module 3 2009](https://reader033.fdocuments.in/reader033/viewer/2022061220/54bb2e674a79593a118b457f/html5/thumbnails/12.jpg)
7. As speed increases…
Central & Peripheral vision decreases
![Page 13: Module 3 2009](https://reader033.fdocuments.in/reader033/viewer/2022061220/54bb2e674a79593a118b457f/html5/thumbnails/13.jpg)
Following intervals 2 Seconds…2 Seconds… Allows driver time to steer out
of problem areas at all listed speeds on a dry surface and stop before problem areas at speeds under 35 mph.
3 Seconds…3 Seconds… Allows driver time to steer out of problem areas at all listed speeds on dry surface and stop before problem areas at speeds to 45 mph.
4 Seconds…4 Seconds… Allows driver to steer out of problem areas at speeds up to 65 mph on dry surface and stop before problem areas at speeds to the legal limit of 65 mph.

OR
**Change direction
![Page 22: Module 3 2009](https://reader033.fdocuments.in/reader033/viewer/2022061220/54bb2e674a79593a118b457f/html5/thumbnails/22.jpg)
Approaching an Intersection
Step 1 (Search) Identify Intersection Identify Controls Check Rear Areas Search for Intersection Risks
Step 2 (Evaluate) Scan Open Side Areas First Scan Closed Side Areas Look for Closed or Changing
Frontal Areas
Step 3 (Execute) Adjust Speed Maintain Lane Position or
Stop Behind Crosswalk Proceed Through Open
Space Area or Stop Behind the Crosswalk
