Oscar Piastri has copped an official warning from the FIA for overtaking under safety car conditions after the chequered flag in the Canadian Grand Prix. The Aussie driver was involved in a wild moment at the end of Sunday’s race when McLaren teammate Lando Norris ran up the back of him while trying to overtake.

Piastri was sitting in fourth place with Norris right behind him, with just four laps remaining. But disaster struck for McLaren when the British driver tried to shoot through a gap that wasn’t there. Norris clipped his teammate and then collided with the wall, ending his race as a safety car was deployed.

Norris immediately admitted fault and said his actions were “stupid”. The Brit said on team radio: “I’m sorry, it’s all my bad. All my fault. Unlucky, sorry, stupid from me.”

Oscar Piastri caught in ‘prohibited’ act after chequered flag

While Piastri escaped all blame for the incident with his overzealous teammate, officials caught him breaking the rules after the chequered flag. The FIA – Formula One’s governing body – found that Piastri was one of seven drivers to overtake another car while the safety car procedure was still in place. The FIA issued official warnings to Piastri, Carlos Sainz, Charles Leclerc, Kimi Antonelli, Esteban Ocon, Pierre Gasly and Lance Stroll.

The driver overtook other cars after the chequered flag, but while safety car signals were still being displayed, following an incident on the start/finish straight involving car 4 (Lando Norris) and car 81 (Oscar Piastri),” the FIA said. “While passing under the chequered flag is not unusual, it is prohibited under yellow flags, safety car or virtual safety car procedures.

“While the drivers were aware of where the incident was, they could have not known if emergency equipment or marshals were being dispatched onto the track, and so have to proceed with caution. We are therefore warning the driver concerned, along with all other competitors. Further breaches may incur higher penalties.”

Norris copped a five-second penalty for causing the collision with Piastri – a punishment that’s virtually pointless considering he didn’t finish the race. Red Bull also launched a protest over the actions of race winner George Russell, believing he deliberately brake-checked Max Verstappen during the safety car period. But the FIA dismissed the protest and Russell retained the victory.

Lando Norris issues public apology over Oscar Piastri incident

Piastri was speaking to reporters after the race when Norris came up and apologised. Norris later said: “No one to blame but myself, I apologise for the whole team and to Oscar as well for attempting something probably a bit too silly. Glad I didn’t ruin his race, apologies to the team. Silly from my part.”

Piastri ended up finishing fourth, ending an eight-race podium streak dating back to the second race of the season. But Norris’ DNF saw Piastri extend his lead in the F1 drivers’ standings from 10 points to 22 – a huge boost for the Aussie as he chases the world championship.

Russell delivered a brilliant pole-to-chequered flag drive to win from Verstappen. Antonelli ended up in third place – earning his first podium at the age of 18 – to complete a brilliant day for Mercedes.

Oscar Piastri reacts to Lando Norris collision

Piastri said after the race that he doesn’t expect the incident with Norris to change the dynamic in the team garage, with McLaren letting their two drivers race each other. “Obviously it’s not ideal for anyone but I haven’t actually seen the incident, so I don’t know what exactly happened,” the Aussie said.

“But if Lando has taken full responsibility then that’s how it goes I guess. Just a bit of a tricky race in general and not an ideal finish.”

When asked about his battle with Norris, which lasted multiple laps, Piastri said he thought it was fair. “He made quite a large move into Turn 10, held my own into the chicane, and it was definitely a tough battle but a clean one up until that point,” he said.

“Again, I’ve not seen the incident, but I don’t think there were any bad intentions involved, I think it was just unfortunate really. I’ll go and have a look obviously but we’re both fighting for a world championship and am very thankful to the team that they allow us to race. I don’t expect this to change anything in terms of that. We’ll keep going racing through the year.”

Andrea Stella says McLaren will review teammate collision

McLaren team principal Andrea Stella was scathing in his reaction to Norris’ brain explosion. “We never want to see a McLaren involved in an accident and definitely we never want to see the two McLarens touching each other,” Stella told Sky Sports.

“It’s something we definitely need to review because this is a very clear principle. At the same time it’s a contact that happened because of a misjudgement. Just Lando misjudged the distance to the car ahead and therefore there was no mal-intent.

“Lando owned immediately, took responsibility for that, but certainly something to discuss and review. Our principles are already in place, our drivers will have something to learn further and we go racing again. It is absolutely a misjudgement that cost Lando quite a lot in the championship. It already cost for the team so definitely an incident that should have not happened.”
