A vehicle disabling device has a solid steel bar with pairs of chains extending therefrom. Extending between the two chains of a pair are bases provided with spikes. When a vehicle engages the device, the spikes puncture the tire and are retained in the tire. This causes the chains to become wrapped around the tire as the vehicles extends forward towards the bar. When the car reaches the end of the device, the bar is caused to be taken up by the chains. The bar engages the frame of the vehicle and presents a hindrance to the rotation of the tires and the steering of the vehicle.
