There has been some strange causes of a red flag so far in F1 2025 Bahrain testing, and on Day 3, another was added to the list. And that was a bus on track down at Turn 10, which caused the session to be briefly halted.

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 topped the timesheets on the second morning of preseason testing in Bahrain as he continued to get to grips with his new Ferrari Formula 1 car.
