I thought I might learn something but wrong kind of physical...
Aw, damn! I knew that I had forgotten something…
I shall correct this in the morning.
On a serious note, the wording for full course caution. Must slow immediately once the caution is in effect. Does that mean we have the countdown from 5 then once it is in effect we have to slow down, or is it in those 5 seconds we must be slowed down and in the limiter by the time the caution comes into effect?
My apologies, I should have been clearer about this.
When a full-course yellow is due to come into effect Race Control shall announce over TeamSpeak "there will be a full-course yellow", before the countdown commences. Drivers should not slow down (excessively) during this countdown period, to prevent potential accidents as a result of each driver slowing at their own pace, but ultimately they should be prepared to hear "full-course yellow is in effect" at the end of the countdown from Race Control. It is
after this announcement that all cars must
immediately be slowed to pit-lane speed, and have their limiters engaged.
The countdown itself shall be relatively quick, as we want drivers to slow down as soon as possible to avoid further incidents. It's main purpose is simply to give each driver the opportunity to make space for themselves (especially if they are in a battle when the first announcement is made) and get ready to slow down for the caution.
I hope this helps to clarify the procedure. I'll make an appropriate amendment to the rule in the morning to remove any obscurities.
Thank you for flagging this oversight.
