All three smashed cars continued sliding across the track and into the barriers at Massenet, with debris and wreckage strewn across the track.
Before he climbed out of his crashed SF-24, Hulkenberg witheringly called the incident “unnecessary”.
The stewards have decreed that the crash does not merit further investigation and so although Magnussen is already on the verge of a race ban with 10 penalty points on his superlicence, he will not face an automatic ban for the next race in Canada.

Sainz was able to recover the pits after waiting for the rest of the pack to plunge by at Casino Square.
After his Ste Devote attack, the Spaniard made light contact with Piastri’s right rear and appeared to already be suffering from a problem when he locked up at Massenet and then went straight on as he braked for the right-hander in Casino Square seconds later.
Under the red flag, Leclerc, Piastri and Norris are allowed by the rules to change to the hard tyres and then attempt to run to the finish without stopping.
