There is disclosed a device and associated method for impeding the motion of a land vehicle travelling along a pathway on a terrain surface. First and second supports are positioned at first and second sides of the pathway, respectively, each capable of being actuated from a compressed condition to an extended condition. A propulsion system is effective to actuate the supports. A barrier extends between the supports at a mean first height that is effective to permit passage of a vehicle when the supports are compressed and supported by each support at a mean second height effective to impede passage of the vehicle when the supports are extended. When the supports are compressed, vehicles pass over the barrier unimpeded. When the supports are extended, the barrier impedes the motion of a vehicle travelling along the pathway. At least one deceleration cable mechanically couples the barrier to a brake system.

Non-lethal, rapidly deployed, vehicle immobilizer system

There is disclosed a transportable device for non-destructively impeding the motion of a land vehicle travelling along a pathway. First and second telescoping devices located on either side of the pathway support a barrier. When the telescoping supports are compressed, the vehicles pass over the barrier unimpeded. When the telescoping supports are extended, the barrier impedes the motion of a land vehicle. At least one deceleration cable mechanically couples the barrier to a braking system. The braking system applies a continuous deceleration force to the vehicle of typically less than 2 g, bringing the vehicle to a stop without damaging either the vehicle or vehicle occupants.
