The most infamous team-mate crashes in F1 history

Congratulations, you've just earned yourself a drive with a Formula 1 team and to celebrate the fact, they've given you a thick book to learn of team operating procedures that you need to read before driving the car.

Page 1, Chapter 1.

"Under no circumstances, do you crash into your team-mate."

It is the golden rule of motorsport, which on occasion has become fools gold after one team-mate or another will collect the other car and lead to some awkward questions back in the garage.

Its perhaps understandable. You've got two Uber-competitive racing drivers in the same equipment racing in funny-shaped circles against 18 others all trying to do the same thing: win.

Eventually, you will hit someone and by the law of averages, every so often it will be your team-mate - as Lewis Hamilton and George Russell found out on the opening lap in Qatar when Hamilton tried to send it around the outside of Turn 1 for the lead.

By the barest of margins he got it wrong and it was absolute pain for Mercedes.

That got RacingNews365 thinking to come up with some of the most famous collisions between team-mates in Grand Prix racing, which is by no means a definitive list.

Ayrton Senna and Alain Prost - Japan 1989

The mother and father of team-mate collisions in F1 is perhaps the second most famous crash in the history of the World Championship.

Coming to Suzuka, Ayrton Senna needed to win the final two races of the season to retain his crown while a non-finish for the Brazilian would hand arch-rival Alain Prost a third crown.

After setting the car up for the race instead of qualifying, Prost stole the advantage and led but Senna chipped away at the lead.

On Lap 47, at the final chicane, Senna was in position for a lunge up the inside, but Prost firmly closed the door. Cue contact and the Frenchman retiring on the spot.

Senna would resume and rejoin, but was disqualified for a push start and rejoining the track by cutting the chicane. Harsh.

That would lay the seeds for the more famous Turn 1 incident 12 months later, but by this time, Prost had firmly taken his #1 sticker to Ferrari.

Sebastian Vettel and Mark Webber - Turkey 2010

This incident is perhaps somewhat overshadowed by the Multi-21 saga of Malaysia 2013, but the duo did not crash, somehow, that day in Sepang and so we go back three years to when the relationship fractured.

Mark Webber was leading in Turkey with Sebastian Vettel slowly closing in, making his move on Lap 40 after the kink on the back-straight.

Vettel moved slowly right across Webber after overtaking - which led to contact right-rear to left-front and sent the German spinning into the run-off all in front of a bemused Hamilton.

Vettel was out on the spot, firmly laying the blame at Webber's door, even if video footage suggested otherwise. Helmut Marko was firmly in the Vettel camp, blaming Webber.

The Red Bull prodigee retired on the spot while Webber finished third after Hamilton and Jenson Button put on a memorable display on how to race wheel-to-wheel in a one-two finish.

Speaking of which...

Jenson Button and Lewis Hamilton - Canada 2011

In the opening laps of the wet 2011 visit to Montreal, Hamilton had hit Webber, gone wide to allow Michael Schumacher and Button through before colliding with his McLaren team-mate on the pit-straight.

Hamilton got a better run out of the last chicane than Button - with both drivers moving to the left. Hamilton was pinched into the wall, breaking the suspension and putting him out on Lap 7.

About four hours later, Button would pass Vettel on the final lap after an astonishing race with a rain delay of nearly two hours and six visits to the pits for the British driver.

It would only take a Vettel mistake for Button to lead half a lap, but it was the right half a lap as he won F1's longest ever Grand Prix.

Lewis Hamilton and Nico Rosberg - 2014-2016

First up, we have Nico Rosberg's clumsy 2014 move at Les Combes in Belgium, trying to hang the W05 around the outside of leader Hamilton. Cue one broken front-wing, one punctured Hamilton tyre and a Toto Wolff looking ready to explode.

Hamilton retired and Rosberg was second.

While that was unexpected, their wipeout in Spain 2016 was not.

Tension was building throughout the first races after a poor start from Hamilton with 57 points to Rosberg's maximum 100 after reliability concerns and a fluffed start from pole in Australia.

Rosberg got the jump on the run to Turn 1 but was in an incorrect engine setting rounding Turn 3. Hamilton dived to the inside, and well, you know the rest..., including the first win for a certain M.Verstappen.

Wolff viewed this as a pressure release after months of tension was building up between the two drivers, but a few races later in Austria, Rosberg suddenly forgot how to turn into a right-hander and clattered into Hamilton on the final lap.

Hamilton won as Rosberg dropped to fourth with damage as Verstappen and Kimi Raikkonen pipped him to the podium.

Oh to be a fly on the wall of those Mercedes debriefs...

Max Verstappen and Daniel Ricciardo - Azerbaijan 2018

The beginning of the end for Daniel Ricciardo at Red Bull - or is it?

Somehow, Verstappen and Ricciardo had avoided a collision in Baku up until their pitstops with some dicey racing.

Ricciardo finally got past and pitted first but on a day the overcut was powerful, Verstappen emerged from his Lap 39 pitstop ahead, meaning Ricciardo would have to do all the hard work again.

He got a mega tow down the main straight as Verstappen weaved, but the Dutchman made one too many as he covered off an inside lunge at Turn 1. Ricciardo was left with nowhere to go except up the back of the sister car.

Christian Horner read his drivers the riot act, which Ricciardo felt was unwarranted as he believed himself to not have done anything wrong. He would later admit this was a factor in his decision to jump from the good ship Milton Keynes for 2019 - a decision history would regard as disastrous.

Sebastian Vettel and Charles Leclerc - Brazil 2019

A definitive moment in the careers of Vettel and Charles Leclerc.

The quadruple World Champion had been handed a drubbing by his sophomore team-mate in his first season with the Scuderia, including a famous win at Monza in front of the Tifosi as Vettel spun out and was 13th.

In Brazil, Leclerc had done a job on Vettel at Turn 1, scything past, but the German tried to put his own back on the Monegasque on the run to Turn 4.

It was eerily similar to Webber in Turkey nearly a decade before as Vettel passed his team-mate, before tapping the front of the sister car.

This time, both were out as Leclerc's front suspension was destroyed - as was Vettel's floor with an apology coming rather quickly over the radio once the rant was done.

In the end, Ferrari boss Mattia Binotto elected to not renew Vettel's contract beyond 2020, effectively ending his front-line career while Leclerc usurped him to become the Apple of the Scuderia's eye.
