A dark day for Kevin Magnussen as he became the first driver to face a race ban under the current penalty points system.
The Danish driver, already teetering on the brink with a tally of 10 penalty points, entered the Italian Grand Prix knowing that a single misstep could have severe consequences.
However, his luck ran out during Sunday's race at Monza when he attempted to overtake Pierre Gasly. As Magnussen tried to pass the Alpine driver down the inside of Turn 4, he locked up and eventually made contact with the Frenchman.
Magnussen received a 10-second time penalty and was then slapped with a one-race ban in Azerbaijan after bringing his total to 12 points in the last 12 months, becoming the first driver to get banned under the current system since its inception in 2014.
But he wasn't the only driver who received penalties. While it wasn't as harsh as Magnussen's, his Haas team-mate Nico Hulkenberg incurred two more penalty points for a collision with Yuki Tsunoda, and Daniel Ricciardo received one point for forcing Hulkenberg off the track.
Alongside time penalties, drivers could carry penalty points for driving infringements. These points expire after 12 months, but if a driver collects 12 points within that time, they get a race ban - a fate Magnussen faces in the next round in Azerbaijan.
GPFans has compiled a list of the points currently accrued by drivers and when they will expire. This article will be updated throughout the year.
