Section: 第５節 安全運転に必要な知識など
Type: True/False
Difficulty: hard

## Question
Crashing into a concrete wall at 60 km/h produces roughly the same impact force as falling from a height of about 14 meters (around the 5th floor of a building).

## Correct answer
True

## Explanation
Section "2. Natural Forces Acting on Vehicles (3) Impact Force" provides this specific example with these exact figures. The speed of 60 km/h, height of 14 meters, and equivalence to the 5th floor all match, so this statement is correct.

## Driving school curriculum
Stage 2 – Topic 5: Human capability and driving

## Source passage (Rules of the Road)
２ 自動車に働く自然の力 (３) 衝撃力 - 時速60キロメートルでコンクリートの壁に激突した場合は、約14メートルの高さ（ビルの５階程度）から落ちた場合と同じ程度の衝撃力を受けます。
