Great to see what would otherwise be mid-pack action at the front for a change and the rewards are well deserved.
The pit closure signs may have been difficult to see but not invisible and are where they always are.
Article 28.14 of the F1 Sports Regulations stipulates that entry into a closed pit-lane other than for essential repairs is a 10 seconds time penalty. All in-race time penalties involve a pit-lane excursion unless the sanction occurs during the last 3 laps of a race, when the time can be added to the finishing time, thus this mid-race incursion and sanction cannot result in a +10.
