The Mercedes Formula 1 team has been fined 25,000 euros because record world champion Lewis Hamilton wore jewelry in the cockpit.
The Brit was not personally punished for wearing his nose piercing in training for the Singapore Grand Prix, but the racing team was punished because an inaccurate form for self-regulation had been submitted to the world motorsport association Fia.
The teams themselves are responsible for ensuring that drivers and vehicles start at the official sessions in accordance with the rules.
However, Hamilton's nose stud was not noted on the form on Saturday.
The 37-year-old said after finishing third in qualifying that he didn't wear the jewelry on purpose to provoke.
The Fia has been tougher since the start of the season and do not want drivers to wear jewelry behind the wheel.
This is dangerous in the event of an accident, it is said, among other things.
Hamilton had to speak to the race commissioners before the race this Sunday (2 p.m. CEST in the FAZ live ticker for Formula 1 and on Sky) because of the incident and referred to a medical certificate from his doctor.
According to his own statements, he should wear the piercing again after various problems such as an infection.
Mercedes was unaware that the seven-time world champion was wearing it again in Asia, according to the Fia report.
In the past few months, Hamilton had adhered to the jewelry ban, but repeatedly questioned its usefulness.
