According to traffic engineers, the average driver crossing or turning at a busy intersection must assess and deal with over 100 potential points of conflict. Thus, it is logical that drivers should deal with such matters as changing gears, signalling and adjusting speed before entering the intersection so that they cay pay attention instead to the points of conflict in the intersection.

The examiner will note actions such as braking or changing gears too late, regardless of whether or not the driver could more easily have performed these actions earlier or later. A stalled engine or excessive acceleration will result in an additional score, while making allowances for all traffic conditions before and during the turns.
