The Formula 1 grid paid a special tribute to Niki Lauda on the parade lap for the Monaco Grand Prix as all 20 drivers in action wore red caps with 'Niki' emblazoned on them.
It serves as a fitting nod to the three-time world champion, who passed away ages 70 this week.
Lauda was rarely seen without his red cap after suffering severe burns in his 1976 crash at the Nurburgring.
With a minute's silence also planned and teams paying tribute in their own way with special liveries and more, the caps served as another reminder of the esteem Lauda is held in on the grid.
