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.
