Q1 lap times determine pole position and the order of the front 10 positions on the grid. The slowest driver in Q1 starts 10th, the next starts ninth and so on. 
All 20 F1 drivers participate in the first period, called Q1, with each trying to set the fastest time possible. Those in the top 15 move on to the next period of qualifying, called Q2. The five slowest drivers are eliminated and will start the race in the last five positions on the grid.
