Read the text and answer the question: Why do the British drive on the opposite side of the road?

The British drive on the opposite side of the road because the origin of this rule dates back to how people traveled in feudal societies. As most people are right-handed, it made sense to carry any protective weapon in this hand. When passing a stranger on the road, it would be safer to walk on the left, ensuring that your weapon was between yourself and a possible opponent. Knights would hold their lances in their right hand, therefore passing on each others' left.
