Boston does this better, where if there isn't traffic, sirens aren't run. At night, sirens are relatively rare. Especially compared to Seattle and Boise where I've also lived.

In Germany, I only ever heard a couple sirens the whole time I lived there, and none directly on my street.

Yes, come to think of it, I have never heard sirens of emergency services drive near at night, but I have occasionally heard them during the day.

How odd. — I rather value my sleep.
