I've heard that a lot of people in the United States don't know how to drive on the right side of the road. What is the right side of the road?

The right side of the road is the side where you are driving. In the US, most roads are built so that the right side is the left side for cars. This is because the US was originally designed as an English colony, and the UK drives on the left side of the road.
