Red Bull’s Pierre Gasly was the surprise pace-setter in an incident-packed first practice session at the British Grand Prix.
The Frenchman, who has struggled in his first season at Red Bull, went 0.476 seconds clear of Mercedes’ Valtteri Bottas with a lap late in the session.
Red Bull’s Max Verstappen was third and Mercedes’ Lewis Hamilton fourth as several drivers had incidents.
Haas’ Romain Grosjean had the worst with a crash in the pit lane and spin.
The Frenchman, who had persuaded Haas to let him try the car in its specification from the first race of the season in a bid to understand their struggles, lost control leaving the pits for the first time because he had too much throttle on when he released the pit lane speed limit.
