Type: Multiple choice
Difficulty: hard

## Question
Regarding following distance for large vehicles, medium-sized vehicles, and semi-medium-sized vehicles, which of the following is correct?

## Options
A. Because the driver's seat is positioned low, the following distance feels shorter than it actually is
B. Because the driver's seat is positioned high with a downward viewing angle, the following distance feels longer than it actually is, so it tends to become shorter
C. The following distance can be perceived the same way as in ordinary vehicles
D. Because the driver's seat is positioned high, the following distance feels shorter than it actually is

## Correct answer
B. Because the driver's seat is positioned high with a downward viewing angle, the following distance feels longer than it actually is, so it tends to become shorter

## Explanation
Chapter 5, Section 4, 2(4) of the Rules of the Road states that large vehicles, medium-sized vehicles, and semi-medium-sized vehicles have driver's seats positioned higher than ordinary vehicles, creating a downward viewing angle that makes the following distance feel longer than it actually is, so caution is needed as the following distance tends to become shorter.

## Source passage (Rules of the Road)
2(4) 特に、大型自動車、中型自動車及び準中型自動車は、普通自動車に比べ、運転席の位置が高く、見下ろす形になり、車間距離が実際より長く感じられるため、車間距離が短くなりやすいので注意しましよう。
