This work proposes a method of calculation of the dynamics of a vehicle movement caused by its turn due to destruction of the front tire. Front tire destruction leads to the sharp slowdown of the car with simultaneous trajectory deviation from the original motion without turning of the driven wheels. The radius of the car movement trajectory depends on the magnitude of the deflection angle. Owing to the angle of deflection it is possible to calculate the radius of the vehicle motion trajectory. This makes it possible to determine not only the place of destruction of the wheel tires, but also the moment of danger for the movement of oncoming cars, departing of the cars from the point of impact, and based on this – materials for technical investigation of the traffic accident.
