In the US, a blinking red light functions like a stop sign. Come to a
complete stop and then proceed if it's clear. The opposing traffic
often has a blinking yellow, or the intersection can become a
four-way stop if both directions are blinking red. In the particular
intersection I was referring to, it changed from a regular stop light
to a blinking stop light after midnight.

There's a blinking yellow light near where I live. It's at a
horrible intersection and I noticed today that a sign had been
installed next to the blinking light that essentially explained how
it should be interpreted.  "Proceed with caution on flashing
yellow."
