Hi Wendy,

The rules at the moment state that there has to be a locking bar fitted when in the pits (this is part of the tech check) but there is nothing to say that it should be fitted at the point of arming up. There are the arguments that each machine is different and some may or may not need one.

I think you are right that there should be locking bars fitted to all machines when arming up as the weekend showed.
