University of Kansas Transportation Services has begun using a new device called The Barnacle instead of towing in certain situations, KU said in a news release Monday.

The Barnacle is a lightweight, GPS-equipped device that is attached to the windshield with two large suction cups, according to the release. the device blocks the view from the driver’s seat and thus prevents the car from being driven. KU describes The Barnacle as “a more passive way” of enforcing certain parking rules compared with towing, and it can be released without the driver having to go to a towing location to get the vehicle. It is also less expensive than towing.

KU says the device will be used to immobilize vehicles of flagrant violators.

Once a device is placed on a windshield, it is held there with 750 pounds of force, making it impossible to remove. Instructions on The Barnacle tell drivers how to make payment in order to receive the code to remove the device.

“It can’t be removed without the release code,” Donna Hultine, director of Transportation Services, said. “There is an alarm if you try to remove it by yourself,” and trying to remove it improperly may also damage the windshield.

Use of The Barnacle began Monday, but it won’t replace the tow truck. Transportation Services will start with two Barnacles but will continue to tow any illegally parked or unauthorized vehicle at its discretion on a case-by-case basis.
