The article present the results of analysis of yaw marks left by a car with nominal pressure in all wheels and zero pressure in one rear wheel. The analysis is a continuation of the research on the influence of tyre reduced pressure on car lateral dynamics in bypassing manoeuvre, discussed at the XII Conference Problems of Road Accident Reconstruction in Zakopane. Apart from the determination of vehicle critical speed on the basis of yaw marks curvature commonly used in road accidenst reconstruction, a new method was applied in the analysis. Owing to this method the slip angle and longitudinal slip of the wheel can be determined on the basis of the geometry of striations which are an integral element of yaw marks. The aim of the research was reached by performing bench and road tests. Next, the results of calculations done on the basis of yaw marks geometrical features were compared with the real values known from the measurements of car motion parameters.
