This article presents the results of the acceleration and deceleration testing of ATV vehicles under maneuvers in linear motion. When measuring lags the braking technique was taken into consideration. The maneuver was performed using three different combinations of the brake use. The first combination involved the use of the rear breaker exclusively, the second involved the use of front brake exclusively and the third the use of brakes for both axles simultaneously. Four vehicles of completely different technical characteristics (capacity and engine power, vehicle weight) were used. The measurements were carried out on dry surfaces of varying adhesion coefficient: asphalt and gravel. The maneuvers were performed to the extreme, i.e. with maximum possible force pressure on the brake levers and the maximum throttle opening. MEREX recorder was used to record the data. The results are represented as graphs (function of time) and tables (maximum parameter value for each maneuver). The results of research supplement specialist knowledge utilized in the process of road accidents reconstruction for vehicles of this type.
