At an intersection with no traffic signals or police officer directing traffic, if the width of the intersecting road is clearly wider than the road you are traveling on, you must slow down to a stop-ready speed (jokō) and not interfere with the passage of vehicles or streetcars traveling on that wider road.

Answer: True

Explanation

This statement is correct. Chapter 5, Section 7 of the Rules of the Road (Passing Through Intersections) states that when the intersecting road is a priority road or is wider, you must slow down to jokō speed and must not interfere with the progress of vehicles or streetcars traveling on the intersecting road. Under the principle of priority for wider roads, vehicles entering a wide road from a narrow road have an obligation to yield to vehicles and streetcars traveling on the wider road.
