Max Verstappen topped the timesheets in opening practice for the Chinese Grand Prix in what was a heavily disrupted session.
Verstappen made the most of what little running there was on the intermediates to go fastest of anyone.
The Red Bull driver ended FP1 1.5s clear of Felipe Massa in second.
It took approximately 45 minutes for first practice to get underway due to weather conditions in Shanghai being unsuitable for the medical helicopter to fly and land at the hospital if necessary.
Once the session got back underway, there was a limited amount of running on track as the majority of the big hitters sat in the garage.
Both Haas drivers struggled in the conditions, spinning on the intermediates.
Verstappen’s 1m50.491s stood at the top of the timesheets for the rest of the session after the virtual safety car was deployed due to Nico Hulkenberg binning his Renault at Turn 3.
The session was then called off with four minutes to go after conditions had worsened and the helicopter could not fly again.
