Pierre Gasly needed a strong weekend to recover from a slow start to his Red Bull career, but the Frenchman has been forced into a pit-lane start for Sunday's Azerbaijan Grand Prix due to a rules violation at the end of Friday's second practice session.
Gasly was called into the weighbridge at the start of the pit-lane as the session concluded, but he drove straight past. Red Bull then carried out a practice pit-stop on his car and changing the tyres, instead of sending him back.
At the end of any practice session, drivers will be randomly called to park their car on the weighbridge, signaled by their number flashing up on the pit-lane entry.
