Reference points-- visual landmarks along a track's path such as physical features on the track's surface, edge, or surroundings which indicate an exact or relative point to begin a different phase in a driving segment. Reference points are usually used to mark the start of a braking zone, a corner turn-in point, apex, and corner exit point. Look for reference points during the early practice sessions, and modify them if needed as you get faster. When selecting reference points be sure to pick something permanent. Do not use a particular skid mark, as it may be very difficult to identify when subsequent skids marks are made. Do not use vehicles at the side of the track as it may be moved. Use fence posts, cracks or patches in the track, or other such items which will not change during the event.
