A new red flag procedure will apply to the TT with immediate effect.
The new system means that a red flag instruction will apply to the entire course regardless of where that incident has occurred.
There will also be no movement on said course by any rider until any incident is completely cleared.
The move was made by Clerk of the Course, Gary Thompson, today.
