Approaching a junction. Look well ahead for signals, signs and road markings. Direction signs may be placed over the road. If you need to, you should change lanes well ahead of a junction. At some junctions, a lane may lead directly off the road. Only get in that lane if you wish to go in the direction indicated by signs or road markings.
