The effect of additional loads on the dynamics of curved movement of the tanker truck was studied depending on the degree of filling with liquid. It was found that when the speed regime changes, additional loads were of great importance due to the following factors: the level of occupancy, the size of the tank, the presence of devices for suppressing liquid vibrations, and the displacement of the center of gravity. When studying the movement of liquid in the tanker truck, it was taken into account that the surface of equal pressure was an inclined plane, since surface forces, forces of inertia and gravity acted on the liquid. An analysis of the action of inertia forces during the movement of the tanker truck with partially filled liquid was carried out. The criterion for stability of the tanker truck depending on the degree of filling of the reservoir with liquid was the coefficient of stability of the car. It has been found that on the controllability of the tanker truck with partial filling with liquid during curvilinear movement, the emerging components of inertia forces applied to the center of mass are proportional to the mass of the car, the speed of movement and its acceleration, the degree of filling of the reservoir with liquid. The presented calculations of the stability coefficient of the tanker truck with partial filling with liquid during curvilinear movement depending on the degree of filling of the tank with liquid at a speed of 45 km/h show that the stability of the tanker truck is the smallest when filling the tank from 35 to 55 %, which is due to the maximum displacement of the center of mass. In the range from 20 to 40 %, the values of the stability coefficient of the tank truck for the investigated water and milk liquids coincide. The use of the obtained dependencies makes it possible to predict the transverse stability of the tanker truck from the degree of filling of the tank with liquid during curvilinear movement. The proposed studies will make it possible to develop an additional correcting device, which is automatically turned on, ensuring the safety of the tanker truck at the transition from a straight road to a curved trajectory, taking into account the additional loads that arise.
