World champion Lewis Hamilton, the only black driver in F1, wore a T-shirt with Black Lives Matter on the front and End Racism on the back.
Hamilton attended a Black Lives Matter march in London and is setting up a commission to increase diversity in motorsport.
Soccer players on fields in England and Germany have taken the knee together simultaneously before games in support of the Black Lives Matter movement, and F1 drivers discussed what they should do during a drivers briefing on Friday evening.
Mercedes is competing in an all-black car instead of the usual silver, while Hamilton and Bottas have End Racism written on the cars halo.
Hamilton praised some drivers for speaking out against racism, but he still feels others need to do more and he raised that in their briefing.
