Ch. 1 · Common Conduct

At night, visibility was good and there were no other vehicles or pedestrians, so I entered a road with a "No Entry" sign. This is not a traffic violation.

[True / False · Medium]

Answer: ✕ False

Explanation

The Rules of the Road define regulatory signs as those that prohibit specific traffic methods. Regardless of traffic volume or time of day, entering where a No Entry sign is posted is a violation. Unless a supplementary sign specifies time restrictions, entry is prohibited at all times.

If there's no one around and I can see clearly, slipping through shouldn't be a problem, right?

Yui

Actually, that's false. A No Entry sign means absolutely no entry, period—it doesn't matter if it's the middle of the night or the road's empty.

Hikari

Wait, really? Even when conditions are perfect?

Yui

Yep! Unless there's a time-restriction sign posted with it, No Entry means never. Think of it as a hard boundary—no exceptions.
