A rotor blade for a wind turbine is disclosed. The rotor blade may generally include a shell having a pressure side and a suction side. The shell may define an outer surface along the pressure and suction sides over which an airflow travels. The rotor blade may also include a spoiler having a fixed end and a free end. The fixed end is connected to the outer surface so as to enable a hinge action, such as a living hinge. The free end includes a top flange and a bottom flange configured to engage opposite sides of the shell and is pivotal relative to the fixed end between a recessed position and an elevated position. The free end has a range of motion limited by contact of the top flange and the bottom flange with the shell. Further, the spoiler is configured to separate the airflow from the outer surface when the spoiler is in the elevated position.
