F1 drivers endure surprise drug test

Early mornings are not anything new for Formula 1 drivers, but they are not used to representatives of the WADA (World Anti Doping Agency) standing at their door at 6 in the morning with a cup in their hand. Tuesday morning saw many Formula One drivers being subjected to a surprise drug test at their homes.

Sergio Perez confirmed that he was subjected to a very "early morning" surprise urine test.

Daniel Ricciardo mentioned on twitter that he, "Got drug tested in the early hours this morning. All of a sudden pissing in your own home becomes difficult with someone staring over your shoulder."

Fernando Alonso's tweet read, "06:42h. Control antidoping."

All Formula One drivers are covered under WADA standards which includes testing at Grands Prix, but they can also be tested out of competition.
