F1 testing RED FLAGGED after bus ventures into track limits

A bizarre three days of testing only got weirder during Friday's final Formula 1 session of the week, with another red flag for a rare reason.

F1 teams have all gathered in Bahrain this week for the one official week of testing before the new season kicks off in two weeks.

However, the week's six sessions have featured some unusual disruptions, including a circuit-wide power cut on day one, a poor decision by the teams not to bring any kind of wet tyres taking an hour out of running on day two, and a pane of glass landing on the track causing a red flag on day three.

Despite all of this, the most unusual incident of the week's testing programme was saved for Friday's afternoon session, the last testing session of the week.

Testing delayed by bus

A brief red flag hampered Lewis Hamilton's final testing session ahead of his first season with the Ferrari team, following a different mode of transport making its way onto the Bahrain track.

A slow-moving bus somehow made it onto the track, driving around within the run-off area, creating a potentially dangerous hazard.

The red flag was immediately waved by the track stewards, and on-track cars made their way back to the pits.

The delay to proceedings was brief, and testing got back underway once more as drivers seek to complete their testing programmes in their new 2025 cars.
