"Always drive as straight as possible through a curve."

Du och jag i trafiken, 28th Edition, page 182

When approaching a curve, slow down appropriately and position your car to the side of your lane which is opposite the direction of the curve. If the road winds to the right, for example, move to the left side of your lane.
As you continue to drive through the curve, smoothly position your vehicle towards the other side of your lane.
When approaching the end of the bend, gradually ease back to the normal position in your lane, then accelerate out of it in a straight line.
