Ch. 7 · 第２節 走行上の注意
When your vehicle breaks down on an expressway, the warning triangle should be placed in front of your vehicle.
[True / False · Medium]
Answer: False
Explanation
Rules of the Road Chapter 7, Section 2, 4(2) specifies, "Place the warning triangle on the road behind the vehicle." To alert following traffic that your vehicle is stopped, you must place it behind your vehicle, not in front. This is a commonly tricky point.
