Counterbalanced inground traffic control device
A traffic control device, for use with a roadway receiving vehicles travelling longitudinally along the roadway, includes a housing mounted transversely across the roadway with an upper supporting surface that supports the vehicles rolling over the housing. A tire puncturing frame comprised of a shaft supporting tire puncturing members thereon is rotatable within the housing between stored and working positions of the tire puncturing members relative to the upper supporting surface of the housing. Offset counterweights are coupled to the frame to bias the tire puncture members towards the working position. A latch bolt threaded into a threaded aperture in the housing selectively retains the tire puncturing frame in the stored position.
