Ch. 5 · 第4節 安全な速度と車間距離
When traveling at 100 kilometers per hour on an expressway, if the road surface is dry and the tires are new, it is necessary to maintain a following distance of approximately 100 meters or more from the vehicle ahead.
[True / False · Medium]
Answer: True
Explanation
When the road surface is dry and the tires are new, a following distance of approximately 100 meters is necessary at 100 kilometers per hour. At 80 kilometers per hour, approximately 80 meters is the guideline. If the road surface is wet from rain or the tires are worn, a following distance of approximately twice this distance may be necessary. This is specified in Chapter 7, Section 2 of the Rules of the Road.
