Ch. 1 · 第２節 信号
On a road where the center line is marked with a solid yellow line, vehicles cannot cross to the right side to overtake, but they may cross the line to make a right turn or to avoid obstructions.
[True / False · Hard]
Answer: True
Explanation
The Rules of the Road prohibit crossing a solid yellow center line to the right side for the purpose of overtaking, but allow exceptions for crossing the line to make a right turn or to avoid obstacles such as road construction or broken-down vehicles. It is the purpose "for overtaking" that is prohibited.
