Generally the safest drivers are those who
- have the best reaction time.
- adjust their driving to the conditions. ✓
- always stay within the law.
- have the best vision.
Answer: B. adjust their driving to the conditions.
The safest drivers are those who adjust their driving to the conditions.
Why this is the answer
The handbook says bad weather means you must change your driving procedures, and it tells truck drivers to match speed to the road, weather and traffic. It also says you must stay aware of conditions so you can make needed changes in speed and position. That is why the safest drivers are the ones who adapt their driving to what is happening around them rather than relying on one fixed habit.
Why the other answers are wrong
- A. have the best reaction time. — The passages do not name reaction time as the mark of a safest driver; they focus on watching conditions and changing speed and position accordingly.
- C. always stay within the law. — The handbook requires obeying the law, but it does not say that staying within the law by itself makes a driver safest; it stresses adjusting speed and procedures to conditions.
- D. have the best vision. — Vision is not presented as the measure of safest driving; the passages emphasize awareness of conditions and making adjustments in speed and position.
Remember it
Think: conditions first, speed and space follow.
