To participate in the International Dutch Championship you need an IDC license. This can be either a year license or a day license. With a day license you can participate in a maximum of 3 IDC races per year and participate in the IDC Endurance on the TT Circuit Assen. Riders holding a valid license from a foreign association must apply for an IDC day- or IDC year license to participate in IDC races.
To obtain an IDC license you can apply via this website. If you have not previously had a motorcycle race license, or have not ride motorcycle races for 3 years, you need to follow a motorcycle race license course. CRT organizes its motorcycle race license course on Thursday 6th and Friday April 7th 2022 at the TT Circuit Assen for the first IDC race of the season on Saturday April 8th 2023.
The CRT motorcycle race license course consists of 5 practical sessions alternated by theory sessions plus a written theory exam with questions about the flag codes.
