Ch. 5 · 第4節 安全な速度と車間距離
When a driver is fatigued, the distance the vehicle travels between when the driver steps on the brake pedal and when the brakes actually begin to take effect becomes longer, so the stopping distance also becomes longer.
[True / False · Medium]
Answer: True
Explanation
This statement is correct. When a driver is fatigued, reaction time becomes longer, and the empty running distance—the distance the vehicle travels between stepping on the brake and when the brakes actually begin to take effect—becomes longer. Since stopping distance is the sum of empty running distance and braking distance, if empty running distance increases, stopping distance also becomes longer. This is specified in Chapter 5, Section 4 of the Rules of the Road (Safe Speed and Following Distance).
