Increasing your vehicle’s speed:
- Increases your field of vision.
- Decreases your field of vision. ✓
- Makes it easier to see cross traffic.
- Has no effect on your field of vision.
Answer: B. Decreases your field of vision.
Increasing your speed decreases your field of vision.
Why this is the answer
The Texas handbook's speed section shows a direct relationship: when the car is stationary, the field of vision is wide, and as speed rises the field is reduced. At higher speeds the driver sees a smaller share of what was visible when stopped. That is why the choice saying speed decreases your field of vision fits the handbook. The handbook does not say speed improves how much you can see, so choices about a wider view or easier cross-traffic viewing do not fit.
Why the other answers are wrong
- A. Increases your field of vision. — A higher speed does not increase your field of vision; the handbook shows it shrinking as speed rises.
- C. Makes it easier to see cross traffic. — Seeing cross traffic does not become easier with more speed, because the handbook says the field of vision is reduced.
- D. Has no effect on your field of vision. — Speed is not neutral for your field of vision; the handbook lists a reduction as speed increases.
Remember it
Picture your view narrowing as the speedometer climbs.
