How do you beat level 33 on vehicles

33. Drive the police car right, and leave the engine running so it will go under the yellow pole as you remove the left stripe. Drop the ambulance and drive it up the ramp to knock away the SUV, then turn back to reach the left but stop short of the red button. Remove the right stripe and knock away the black car with the police car. When the ambulance hits the red button, the yellow pole should fall right into place. It lets the lower police car cross to the left and knock the SUV there. You will have to hurry right to reach the green spot in time. But there is no score problem.
