One of the most accessible types of motorsport is high-speed maneuvering in cars. As a rule, any civilian car with passed technical inspections can participate. The races take place along a given trajectory between the chips (pylons).
Also, light off-road competitions are held for amateurs. In Belarus for such cars there is a separate category "Glamor", the participants of which are invited to drive in simpler sections without the risk of damaging the car.
You can also take part in the rally of 3 categories, where the task of the participants is to follow the route in accordance with the allotted time. Everything is like rallying, but safe and at lower speeds.
In very many - for example, in all sorts of "off-road" rallies in Karelia and the Leningrad region - just submit an application and that's it. Owners of good cars and a sufficient amount of money travel to Germany to the famous professional Nürburgring racetrack - rent a circuit alone or a joint and ride on your health! By the way, it was recently bought out by a Russian oligarch.
Well, the easiest way is to find rally drivers or mud-mixers in your region, depending on what kind of car you have :).
