Ch. 5 · Driving Method

Which of the following is correct regarding passing on slopes or roads with cliffs?

[Multiple choice · Hard]

• A.Because starting on an uphill is difficult, the principle when passing is that the ascending vehicle yields to the descending vehicle.
• B.On a road where one side has a cliff with a risk of falling, if safe passing is not possible, the vehicle on the side opposite the cliff must come to a complete stop and yield.
• C.On a slope, if there is a turnout nearby, even the ascending vehicle should enter the turnout and wait.✓
• D.When passing on mountain roads, the shoulder is not prone to collapse, so you may pull over all the way to the edge of the shoulder.

I'm pretty sure the uphill car should always yield since it's easier for them to restart… right?

Misaki

Actually, the correct answer is that if there's a turnout nearby, even the ascending vehicle should use it and wait—it's the exception to the usual rule.

Hikari

So convenience beats the general principle when a turnout's right there?

Misaki

Precisely. Flexibility with turnouts keeps traffic flowing safely, even on slopes.
