The current F1 regulations have limited the number of helmet designs a driver can have during the season. The driver has just one opportunity to race with some unique colours which were done as tributes to someone or something. Here is a list of five of the great one-off design helmets.
Ericson's Monaco Special
Monaco Grand Prix is one of the most exciting races on the F1 calendar, and in 2014, Marcus Ericsson racing for Caterham brought his Monaco helmet for the event, paying tribute to Swedish F1 legend Ronnie Peterson.
Raikkonen's Hunt Special
At the 2012 Monaco GP, Kimi Raikkonen paid tribute to James Hunt with a replica of the 1976 F1 champion's helmet design. The Finn again came with helmet design at the 2013 Monaco GP, but he got into a spot of trouble with FIM.
For Jenson Button, the year 2014 was an emotional one because of his father's demise. His father, John was a prominent character in the F1 paddock. Button paid tribute to his father by wearing a pink ‘Papa Smurf' (John's nickname) helmet design.
The most recognizable design among all of the one-off designs is this unique helmet. Lewis Hamilton used his one permitted design change of the season at the 2016 Brazilian GP. He wore a helmet, which featured Ayrton Senna's famous yellow design on it.
The Aussie Daniel Ricciardo knows how to give a proper tribute with his one permitted design change of the season. He paid tribute to iconic stuntman Evel Knievel with a pretty damn cool design at the 2016 US GP.
