Ch. 4 · Pre-Drive Conduct

I drank alcohol the previous night, but since it was now morning, the effects of alcohol had completely worn off and there was no problem with driving.

[True / False · Medium]

Answer: ✕ False

Explanation

According to the Rules of the Road, even if you drank alcohol the previous night, you should be aware that you may still be under the influence of alcohol when driving the next morning. The passage of time alone cannot determine that the effects of alcohol have worn off.

I mean, if I slept it off, the alcohol's gone by morning, right?

Misaki

Not necessarily. Time alone doesn't guarantee the alcohol has left your system — you could still be impaired the next morning.

Hikari

Whoa, seriously? Even after a full night?

Misaki

Yes. You can't just assume you're sober based on the clock. This statement is false — never drive if there's any doubt.
