Qualifying for the Italian Grand Prix was delayed after gravel needed to be swept off the track thanks to a chaotic end to Q1.
A frantic end to the session at Monza saw several drivers battle to control their cars, with debutant Franco Colapinto and Kevin Magnussen both throwing gravel onto the circuit.
The clean-up operation was conducted between Q1 and Q2, with the delay only lasting a matter of minutes, before the green light was given for the rest of the action to continue.
Messy conclusion headlines busy Q1 session
Colapinto's moment at the exit of Turn 7 was the biggest scare of the session, and the Argentine did well to regain control of his Williams before any serious damage could be done.
It did mean that his second push lap was a bust, and his first F1 qualifying session ended with him in 18th place.
