GOOD FORWARD VISION

When you are leaving the dual carriageway, you will normally use a slip lane. There are other situations when the dual carriageway finishes at a roundabout. The slip lane is usually long enough for you to move into before you start slowing down from a higher speed. You must use good forward vision to locate the slip lane and assess its length. Good judgement and positioning are required to dominate your space. You must indicate early to give warning to following vehicles, this will give a prior warning and alert them to what you intend to do.

AVOID SLOWING DOWN

Where possible, do not slow down on the dual carriageway, this is what the slip lane should be used for. Slowing down too early, especially on the slip lane if it is not necessary will mean you will become a hazard to following traffic. Keep an eye in the mirrors to see what the traffic flow is like behind, then move across into the slip lane as early as possible. Once you are in the slip lane cancel the signal and then slow down to a suitable speed for the possible bend or junction at the end.
