There is a good chance Haas will be told to change their car colour before the season starts. This is because of the fact the Court of Arbitration for Sport (CAS), announced in December that Russian athletes were banned from competing at world championship events for the next two years.
The ban related to state-sponsored doping and cover-ups at the 2014 Winter Olympics following investigations by WADA, which had recommended a four-year ban.
The Russian Automobile Federation confirmed in February that this would extend to the FIA's world championships, meaning Mazepin cannot race under the Russian flag this year. Mazepin is also prohibited from using national emblems, flags or symbols, as well as the word "Russia" or "Russian", on his clothing or equipment.
It is quite clear the Haas cars have been painted to look like the Russian Flag so I would not be surprised to see them forced by CAS or WADA to change the colours.
