All F1 Grand Prix races have practice and qualifying sessions for the participants. The racers can take part in the practice sessions on Fridays and Saturdays. While individual practice sessions are not mandatory, it is imperative for the drivers to take part in at least one Saturday session.
The qualifying session of Saturdays in Formula 1 is divided into three
distinct parts. Every session has multiple drivers on track
simultaneously. The drivers are prohibited from stopping unnecessarily
on the circuit or obstruct other drivers.
During the first 20 minutes, 22 cars can run laps. The six slowest cars
drop out to fill the final six grid places.
Sixteen remaining cars run in a 15-minute session. The six slowest cars
drop out to fill places 11 to 16 on the grid.
The third part is the final 10 minute session. The remaining 10 cars
compete for the starting order for the top 10 grid places.
