The invention provides a vehicle driving behavior detection method and device, equipment and a storage medium. The method comprises the following steps: acquiring a video stream, wherein the video stream comprises a preset lane and a specified direction of the lane; performing target detection and tracking on the vehicle in the video stream to obtain a driving track corresponding to the vehicle, wherein the driving track comprises a plurality of track points indicating the position of the vehicle; determining the displacement of each track point relative to other track points according to the position information indicated by each track point in the plurality of track points; and in response to the situation that the included angle between the displacement of any track point in the track points relative to other track points and the specified direction reaches a first preset threshold value and the projection in the specified direction reaches a second preset threshold value, determining that the vehicle does
