Webber believes to safety improvements must be made soon

"Together with the FIA, we are looking to up the standards," said Williams driver Mark Webber, a leading light of the Grand Prix Drivers' Association.

"In terms of the medical back-up, compared to what we have at races which is absolutely full-on, I think we are definitely a bit shallow.

"So, it needs to be addressed quite quickly and I am sure it will be."

Concerns over safety in testing sessions were recently highlighted with McLaren test driver Alex Wurz' crash in the build-up to this weekend's Monaco Grand Prix.

"All the drivers are together on it and we have also singled out some tracks in general which we want to improve safety as well, and that is very important for the drivers at the moment," Webber added.

Italian Jarno Trulli, last year's winner in Monaco and another spokesman for the GPDA, agreed that something had to be done urgently.

"All the GPDA members are concerned about it, we raised this problem and discussed it several times because we really believe the safety during testing is not good enough, or not as good as during the races," said the Toyota driver.

"We really are wanting to push the teams, the FIA and everyone to raise the safety standard during testing, because I cannot see why we shouldn't have the same safety standard."
