The method of determining the speed of a bus before its overturning is considered. According to statistical studies, it was found that rollover of buses is a fairly common type of traffic accidents (road accidents). However, in this kind of accident, a large number of casualties and even deaths are recorded. In such cases, the investigator-investigator must identify the culprit in the accident, as a rule, it can be a master for the production of vehicles on the line, if the cause is a bus malfunction. In addition, it can be drivers of other cars or pedestrians. The driver of the bus, who took the wrong actions in the current dangerous situation, can also be guilty. The most common cause of an accident is the driver violating the speed limit. Therefore, the investigator-investigator must determine how fast the bus moved before tipping over. For this, there is a standard method for determining it. Based on the received speed value, it is concluded whether the driver violated or did not violate the established speed regime. However, this technique will give excessive values ​​of speed, for example, if the driver has made a maneuver "rearrangement", known as the elk test. Thus the bus, moving on an arc in the beginning in the right, and then to the left with the resolved speed, has risk to overturn. This is due to the impact of the alternating centrifugal force, as well as the additional forces acting on the bus bodies, due to the compression-expansion of the suspension springs. The article defines the speed of the bus before the overturning, at the time of the maneuver "rearrangement".
