Ch. 6 · Hazardous Areas

Which of the following is NOT listed in the Rules of the Road as a measure to take when brakes fail on a downhill slope?

[Multiple choice · Medium]

A.Downshift quickly
B.Pull the handbrake
C.Turn off the engine switch✓
D.Drop the wheels into a ditch on the mountain side

Answer: C: Turn off the engine switch

Explanation

The Rules of the Road (6) describes measures such as "downshift quickly and pull the handbrake. If that still does not stop the vehicle, drop the wheels into a ditch on the mountain side," etc., but there is no mention of turning off the engine switch. Therefore, option 3 is correct.

Hikari

I'd turn off the engine to stop it from pulling the car downhill, right?

Misaki

Actually, that's not listed in the rules. The correct measures are downshifting, using the handbrake, and as a last resort, dropping your wheels into a roadside ditch—but never turning off the engine.

Hikari

Wait, so option 3 is the one that's NOT correct?

Misaki

Exactly. The engine switch isn't mentioned anywhere in the official procedures.
