Organisers of the Classic TT and Manx Grand Prix will carry out a course-wide test of the electronic flag system tomorrow morning (Wednesday).
The test will take place between 7am and 9am, with digital displays positioned at flag points around the Mountain Course illuminated simultaneously.
The system forms part of the events’ Safety Management System and provides an additional layer of protection alongside the traditional red flag procedure operated by marshals.
It allows the Clerk of the Course to signal a race stoppage instantly, helping improve visibility and speed up communication between riders, marshals and officials.
The test will not affect public road access and road users will not need to take any action.
Clerk of the Course Gary Thompson MBE BEM said the early-morning timing had been chosen to minimise disruption.
He added that organisers appreciated the cooperation of residents and road users as final safety preparations continue ahead of this year’s Classic TT and Manx Grand Prix.
