Was on a bus earlier that got stuck in a main road because there
wasn't enough room to pass another bus coming in the opposite
direction. Both buses were stuck with queues of cars in either
direction.
After a few heated words (nothing offensive I hasten to add), our
driver shouted to the other 'I'm going into Code Red'. Anyone know
what code red is?

I have no idea how they got out of that problem, there was little
either bus could do to get out of it.

Maybe he walks back down the queue of cars behind him getting them each to
reverse a little to close up the gaps until there's room behind him to
reverse out of the way of the other bus.
