Knowing the meaning and actually applying the flag codes is an essential aspect when riding on a track. Riders must immediately adapt their riding behavior on the track to these flag codes.
The TT Circuit Assen uses digital flag panels called "digiflags". The digiflags can be displayed at 18 positions along the circuit.
Primarily only the digiflags will be displayed. Digiflags can be supplemented or accompanied by flag signals from the track marshalls. The signal that is shown first takes precedence.
For the participants of the CRT racing license course for the IDC license, a written exam is held in which the meaning of the digiflags is asked.
The meaning of each flag should be described as extensively as possible.
