To move closer to the goal where each car is parked alone at the correct curb, we can first move car_0, which is currently behind car_2 at curb_0, to the empty curb_1. This action clears car_2 and allows flexibility in subsequent moves.

New State Description:
Curb_0: car_2 is now the only car parked and is clear.Curb_1: car_0 is now parked and clear.Curb_2: car_1 is parked and clear.Curb_3: car_3 is parked and clear.
