The afternoon session of Formula 1 preseason testing was briefly interrupted Friday when a shuttle bus drove on the track. In a bizarre scene, a red flag was waved to halt testing as a white bus drove slowly on a runoff area of the track at Bahrain International Circuit.

Lewis Hamilton said he was "really enjoying" his new Ferrari as he set the second-fastest time on day two of Formula 1 pre-season testing in Bahrain. The seven-time champion, who has moved to the Italian team this year after 12 seasons with Mercedes, was pipped to fastest lap by 0.031 seconds by Williams' Carlos Sainz.
