Hikari

I can change lanes if I signal, right?

Misaki

Not if it forces a car behind you to brake or swerve suddenly. That's true—you must not change lanes in that case.

Hikari

So even with a signal, I still have to check behind carefully?

Misaki

Absolutely. Your lane change can't put others in danger, signal or not.
