1. An anti-skid device for enhancing traction on slippery roads comprising:
a housing defining a cavity and having housing teeth along an inner periphery of the housing;
at least three arms protruding radially from the housing;
a hub rotatable within the cavity of the housing by a handle, the hub is configured to extend the at least three arms in a direction outward from the hub when the hub is rotated in a first direction and retract the at least three arms in a direction inward to the hub when the hub is rotated in a second direction opposing the first direction;
each of the at least three arms having an associated anti-slip element extending from a side surface and being configured to contact a tread surface of the vehicle tire; and
a lock comprising lock teeth configured to lock the hub in relation to the housing to prevent extension of the at least three arms when the anti-slip elements are engaged against the tire tread, wherein the lock comprises a locking element located between the hub and the housing, and the lock is movable between a first position where the lock teeth engage the housing teeth preventing rotation of the hub and a second position wherein the lock teeth are out of contact with the housing teeth allowing rotation of the hub.
