Keep well to the left unless you're about to overtake or turn right.
Always be able to stop your vehicle well within the distance from which you can see the road to be clear.
Take special care when it is misty or rainy, when light is bad, or when roads are wet, slippery or otherwise dangerous.
At nights, always drive within the limit of your lights. If you are dazzled by oncoming lights, slow down or even stop.
Go slow in narrow roads or winding lanes.
