Ch. 5 · Driving Method

When the vehicle ahead is signaling to move toward the center of the road to exit the road, you must not obstruct its lane change, even if you would have to brake suddenly to avoid it.

[True / False · Hard]

Answer: ✕ False

Explanation

Section 3 "Crossing, etc. (4)" of the Rules of the Road states: "When the vehicle ahead is signaling to move toward the left edge, center, or right edge of the road to exit the road, you must not obstruct its lane change. However, this does not apply if you would have to brake or steer suddenly to avoid it." Because there is an exception, this statement is incorrect.
