If the road has four lanes and 60 trucks in each lane, the total number of trucks in all the lanes is 60*4 = <<4*60=240>>240.
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 = <<480*4=1920>>1920
In all the lanes, the total number of vehicles is 240 trucks+1920 cars = <<240+1920=2160>>2160
