THE 107% RULE EXPLAINED 
 
The 107% rule was introduced to increase drivers safety by keeping the slower drivers off of the track. By doing this the faster drivers don't have to lap so many times thus increasing the safety of the drivers. 
How the rule works is like this. You take the pole time and add an extra 7% to it. So if the pole time is 1m21.5 sec's you work out the 107% time by saying 81.5 divided by 100, then multiplied by 107 is 87.205, or 1m27.205s which is the 107% time limit. 
This rule was brought in at the start of the 1997 grand prix season. Since then it has been used on three races upto Hockenhiem, Germany 1998. 
   1) Melbourne '97 both Lola drivers (Ricardo Rosset and Vincenzo Sospiri) and Petro Diniz failed to qualify. Diniz was allowed to race however because during the practice sessions he had what the FIA described as an 'extraordinary number of mechanical failures.' 
   2) Spain '98 Ricardo Rosset this time in a Tyrrell failed to qualify by a tiny 6/100s of a second. 
   3) Monaco '98 and yet again Rosset Dnq's. 
You properly won't be surprised to hear that in June the FIA were thinking of calling it the 'Rosset Rule' - However they decided against it
