Ch. 1 · 第２節 信号
When a flashing yellow signal is displayed, you must slow down to a stop-ready speed (jokō) and proceed with caution for other traffic.
[True / False · Medium]
Answer: False
Explanation
A flashing yellow signal means "proceed with caution for other traffic," but there is no obligation to slow down to jokō. Correctly, you may proceed at normal speed while paying attention. Be careful not to confuse this with jokō.
