Ch. 5 · 第４節 安全な速度と車間距離
The stopping distance on wet road surfaces with worn tires can extend to approximately three times that on dry road surfaces with tires in good condition.
[True / False · Hard]
Answer: False
Explanation
The Rules of the Road state that stopping distance on wet road surfaces with worn tires can extend to approximately twice that on dry road surfaces with tires in good condition. Since it is twice, not three times, this statement is incorrect.
