Formula 1 stewards have decided to take no further action after summoning every team for pit-incidents during the Abu Dhabi Grand Prix.
During the race, Lewis Hamilton, Pierre Gasly, Max Verstappen, Logan Sargeant and Zhou Guanyu were all placed under investigation for infringements during their pit-stops.
The FIA later clarified that this was under Article 34.13 of the Sporting Regulations, which states that eye protection is "compulsory" during pit-stops for team members.
In the hearing, the stewards studied reports and video evidence, and determined that multiple breaches of Article 34.13 were committed.
However, the video evidence was "insufficiently clear" to determine whether, if a visor was open, other appropriate eye protection was worn, such as goggles.
The stewards also found that there were "numerous examples of eye protection not being used."
In the verdict, the stewards stressed the importance of eye protection for all those working on cars at pit-stops, and urged teams to ensure the article was respected in the future.
