Hamilton and Rosberg 1-2 in opening practice

Course workers attended to Perez's Force India

After a 3-week break Mercedes drivers Lewis Hamilton and Nico Rosberg resumed their position at the front of the F1 parade by running 1-2 in opening practice for the Hungarian GP.

Hamilton's lap of 1m25.141s was just enough to nip Rosberg who managed a 1m25.250s time.

Kimi Raikkonen, driving for his job at Ferrari was third with a time of 1m25.812s.

Practice was interrupted when Sergio Perez spun across the track, hit the barriers, and rolled his Force India.

The Mexican driver came to rest upside down, but he was able to get out quickly and was taken to the medical center for a check-up and deemed OK.

"It was a really bad accident, really unlucky," he told Sky Sports F1.

"I went in at the wrong angle, which made the car roll over, but everything's all right.

"It was a bit of a strange accident, I thought I was under control but I guess the Astroturf was very dirty and that's why I went into the wall, but we have to check everything in detail."
