Taxis and occasionally even limousine buses are notoriously guilty of this...

Sure, better than falling asleep and crashing, but come on, all the konbinis around here have parking slots big enough for trucks.

For example, in my romanian road code you are not permitted to turn right at a red light unless there is a separate green blinking arrow pointing that way (and no, the blinking green isn't always there). I know that in the US the default is you can turn.

How about stopping on the side of the road? Here it's permitted anywhere it's not explicitly forbidden. And I think taxis have an exception and they can really stop anywhere for a few moments to pick up/drop people. They may get cursed at but it's legal.

Here's a little mind twister:

In the US there are Right Arrow signals. A Red signal indicates you can turn right if it's safe just like ordinary Red signals. A Green signal indicates you can turn right, obviously.

Wait, what?

You see, this Right Arrow signal exists alongside ordinary signals at an intersection. Specifically when the ordinary signals are Green (so you can go straight ahead or turn as appropriate) but the Right Arrow signal is Red, you cannot turn right. Usually this is because someone is crossing the intersection and you would risk running them over.

This specific arrangement is very rare.

Never saw single red lights. Just the blinking green when it's permitted. Btw blinking green implies yield to other cars, pedestrians or anything else that's in your way.
