A red traffic light only means stop sometimes, but sometimes you can go if you’re turning right.

It always means stop. You can turn right on red (in most places) but only after you stop first and you must yield to crossing traffic. Unfortunately, not everyone knows this - I’ve met many people who think “right on red” means you can treat it like a green light as long as you’re turning right.

What really gets me pissed is the signs that say “right turn on red after complete stop” which implies that isn’t the case fucking everywhere, when it is the case.
