Championship leader Oscar Piastri secured the fastest lap in the sole practice session ahead of the fourth Grand Prix in Miami. His McLaren teammate Lando Norris was on track to achieve the second-fastest time but was unable to complete his lap due to a crash involving Oliver Bearman. Consequently, Norris finished in twelfth position. Charles Leclerc clocked the second-fastest time, followed by Max Verstappen and the Williams drivers.
