Since in each lane the number of cars is twice as many as the number of trucks in all the lanes, there are 2 * 240 = 480 cars in each lane. The total number of cars in all the lanes is 480 * 4 = 1920. In all the lanes, the total number of vehicles is 240 trucks + 1920 cars = 2160. So the final answer is 2160. <hau> Idan hanya tana da hanyoyi hudu da motoci 60 a kowace hanya, yawan adadin motoci a duk hanyoyi shine 60 * 4 = 240.
