The first practice session in Mexico featured a lot of Friday drivers, including Giovinazzi, Leclerc, Gelael and Antonio Celis, who was driving in front of his home crowd. Unfortunately, he spun his Force India and hit the barriers, causing a red flag whilst the incident was sorted out. Stoffel Vandoorne only managed three laps due to an engine problem, Verstappen spent much of his morning in the garage, and Brendon Hartley stopped out on track, before getting going again only to disappear in the garage.
