How do you beat level 8 in vehicles?

Answer 1

1) Use the fire truck to push the ambulance backward, fully onto the stripe.

2) Remove the stripe and drive the ambulance left to nudge the ramp.

3) The tire rolls down and knocks away the black car.

4) As the tire rolls, quickly remove the stripe and drive the police car to the park spot

(This is how to get the star for the level.)
