Current article deals with increasing of the lateral stability of transport units used to transport liquid or bulk cargo when the container is not completely full. Cargo transportation in this case has specific challenges when vehicles are moving on surfaces with the longitudinal slope. It happens because while transporting liquid or bulk cargo, the load's center of gravity changes, and the result is the overturning moment. It was found that the tanker's fill level effects on the shift in the center of gravity of liquid cargo at various vehicle tilt angles. Increasing the maximum vehicle tilt angle to 20° leads to a shift in the center of gravity of liquid cargo of up to 0.1 m at a tanker fill level of 40%. As the tanker's fill level increases in the examined range, the shift in the center of gravity of liquid cargo decreases by 25%, which leads to an increase of vehicle lateral stability. Increasing the tank's fill level by 35% reduces the liquid cargo's center of gravity by 18%, and makes it possible to ensure reliable vehicle lateral stability even when the maximum vehicle tilt angles increase by 12%. The research results allow to predict the lateral stability of a vehicle in the case of incomplete filling of a container carrying liquid cargo during curvilinear movement from the maximum longitudinal slope.
