[True / False · Medium]

Hikari

So at night you 'may' use the warning device and lights—sounds like you have a choice.

Momoka

Nope, that's false! The rule says you 'must' turn them on—it's a legal requirement, not an option.

Hikari

Oh, the wording totally tricked me!

Momoka

Right? 'May' feels like permission, but on expressways at night those lights and devices are mandatory!

At night, you must also turn on the hazard lights, parking lights, or tail lights.
