The tests were temporarily stopped as the lights went out at the racetrack

      When there were just under two hours left before the end of the first day of testing, the session was stopped with red flags due to the fact that the electricity went out at the circuit - the lighting on the track went out, the power supply in the pits was lost.

      The emergency lighting turned on in the pits, the mechanics took out flashlights that suddenly came in handy, and the racers used their phones.
