Driving in most of the world? Keep right.
Meeting a loaded lumber truck on a one-lane road somewhere east of Thurso? Go left because for some reason it's different from every other norm of meeting in the world.

It's not just a quaint quirk when you are in danger of being run over by an angry fat mat in a big truck with nationalist flags painted on it.
Roman Soldiers marched on the left so their swords were exposed rather than their body (most were right handed).

Napoleon was left handed so he changed it around to suit him. So all of Europe followed too, but the British Empire stayed the opposite way.
