Verstappen, Russell and Hamilton all face post-qualifying investigations
The Red Bull and Mercedes drivers are under investigation by the FIA stewards in Mexico City after they were seen causing a traffic jam at the end of the pit lane.
Three-time world champion Verstappen was pinged for a similar incident at the Singapore Grand Prix, for which he was reprimanded.
The FIA later admitted to F1 teams that the controversial decision to give Verstappen a reprimand was a mistake.
It was confirmed that Verstappen should have received a standard three-place grid penalty.
The FIA promised they would not use the Singapore decisions as a precedent.
Meanwhile, Lewis Hamilton is under investigation for allegedly not slowing sufficiently under yellow flags caused but a spinning Fernando Alonso at the end of Q1.
Like Hamilton, Yuki Tsunoda and Logan Sargeant are also under investigation.
