If no traffic is present when you are taking a curve, it is a good idea to start:

If no traffic is present when you are taking a curve, start on the outside of the curve to increase your line of sight and the effective radius of the turn. As you turn, move toward the inside of the curve. As you pass the center of the curve and prepare to exit, move back toward the outside position. Remain aware of changing road and traffic conditions and adjust as necessary.
