Observation, Speed & SpaceStandalone practice
On an open road, you speed up from 20 mph to 60 mph. What happens to your field of vision, the area that you can see well while you look ahead?
Correct answer: It becomes much narrower, so you notice less at the sides of the road
Why
At about 60 mph, the area that you see clearly is much narrower than when you drive slowly, so cars, people and animals at the side of the road are easier to miss. At the same time, you need more distance to stop. Keep your speed down near intersections and driveways, and move your eyes often to check the sides and the mirrors.
