Haas drivers receive black flags during FP1

Both Haas drivers have been given black flags during FP1 of the Monaco Grand Prix for what is being described as "Telemetry and radio issue".

The pair were brought back to the pits after the team were unable to communicate with the drivers on track. The FIA intervened after the drivers missed the black flag.

Kevin Magnussen and Romain Grosjean set times of 1:14.743 and 1:16.485 respectively.

After the incident, Haas said: "Telemetry and radio issue - we can’t communicate with drivers. FIA stepped in so we could get cars back to pits as pit board’s weren’t doing the business."
