He was driving at Silverstone this week as part of Pirelli’s latest tyre development activity as it prepares its 2020 compound range.
Red Bull and Williams participated in the two-day test on Tuesday and Wednesday after the British Grand Prix, but the second day ended early after Buemi suffered a big crash exiting the high-speed right-hand Abbey corner.
Buemi was unhurt in the accident and released by doctors following a thorough medical examination. The cause of the incident is under investigation.
The next Pirelli test will take place on September 12-13 at Paul Ricard.
