The condition of shock-absorbers is one of factors influencing the in active-safety technology which help drivers to control of their vehicles in the motion. It stuck in the drivers' consciousness, that the damage of the shock-absorber causes the elongation the braking path and the lowering of the drive comfort. The remaining consequences of the worse conditions of shock-absorbers they are not known for the drivers' generality. This impinges on the vehicle motion parameters, its steerability and directional stability. The results of investigations and the analyses of the inefficient shock-absorber influence on vibration damping and the motion of the car were introduced in the presented work. The damping coefficients of the shock-absorber and their change during the exploitation were defined on the basis of test-bed investigations. Road tests were carrying over, on the basis which, try to catch the influence of fault on steerability and the directional stability of the vehicle motion. Road tests were carry over on the A class car. There was compared behaviour of the efficient vehicle and with the worn out shock-absorber. To comparison coefficients various tests are proposed. The road tests were carrying out on A class car with the 4WD driving system, equipped with the drive stability system. Results from individual tests were introduced on graphs.
