Multi-purpose forest fire fighting vehicles consists of many interconnected parts, each with its own mass and oscillatory characteristics. When the vehicle is operating on a forest road, it vibrates, reducing the smoothness of the movement, causing dynamic loads, and at the same time making the chassis more torsion. In addition, when working on forest roads with poor road surface quality or steep hills, the body of the vehicle appears to oscillate, causing instability, and the pitch and roll angles of the body are large, which can lead to the vehicle rolling over. Simultaneously with the horizontal oscillations are the vertical oscillations, which adversely affect the driver as well as the fire extinguishing systems on the vehicle. This paper presents the results of research on the influence of road quality on the oscillation of Multi-purpose forest fire fighting vehicles. The results of the vehicle oscillation survey have found the reasonable working mode of the vehicle in different forest ground irregularities, which are: On class C roads, the vehicle should be driven at a speed v ≤ 15 km/h, and on class D and E roads, we let the vehicle run at a speed of v ≤ 10 km/h.
