Ch. 5 · Driving Method

At intersections where visibility to the left and right is limited, you must always slow down to a stop-ready speed (jokō) even when traffic is controlled by traffic lights.

[True / False · Medium]

Answer: ✕ False

Explanation

The Rules of the Road state that when passing through an intersection where visibility to the left and right is limited, you must slow down to a stop-ready speed, but this does not apply when traffic is controlled by traffic lights or when traveling on a priority road. Therefore, slowing down is not required when traffic lights are present.

Bad visibility means I should always slow down, right? Even with a green light?

That's false. You must slow to stop-ready speed at such intersections, but not when traffic lights are controlling it or you're on a priority road.

Oh, so the light changes the rule?

Exactly. The word 'always' is the trap here — traffic signals and priority roads are exceptions.
