This fault typically occurs when you attempt to pull away from a stationary position in a gear other than first. Normally this will incur a rider fault. The examiner will tend to look more deeply into this if s/he feels that this is a persistent problem for you. During your test if you find yourself being asked to pull over and stop several times the chances are that the examiner is concerned that you are failing to change down gear properly before coming to a halt. Stalling at junctions, or when entering a roundabout, is often caused by trying to pull away in the wrong gear. This will frequently be considered a serious fault as invariably you will have moved out into the road a short distance. Try to get down into slow control and first gear before stopping.
