Drivewayspikes discourages unwanted vehicles from entering your driveway. They are an excellent alternative to chains, ropes, milk crates or other driveway barriers. There’s nothing to move when you leave or return home. Drivewayspikes can be used in restaurants, night clubs, hospital parking and even cell phone lots at airports. The flexible rubber base and molded rubber spikes will not damage vehicles as they are driven over, but can hold up to extreme use and weather conditions.
