A method, system, and device are presented for providing countermeasures against errant vehicles. A countermeasure controller determines a vehicle-velocity vector based on data from one or more sensors and compares the vehicle-velocity vector to an authorized-velocity vector. The vehicle is determined to be an errant vehicle if the vehicle-velocity vector is not aligned with the authorized-velocity vector. Then, the countermeasure controller may apply countermeasures to the errant vehicle. The countermeasures include electronic countermeasures, informational countermeasures, and physical countermeasures. The countermeasure controller can provide information to other drivers about the errant vehicle via personalized communication or electronic warning signs. The countermeasure controller can be configured to detect entry of vehicles into security areas based on data from one or more sensors. The countermeasure controller may then apply countermeasures to vehicles attempting unauthorized entry into a security area.
