WARNING: ANIMAL/VEHICLE CROSSING

This article describes a warning device marketed by the Sav-A-Life Corporation of New York. This device fits on the bumper of most vehicles and produces an ultra-sonic sound to warn animals that a vehicle is approaching. The warning system consists of two small bullet-shaped devices that are easily attached. When a car is moving more than 30 mph, air flowing through the devices creates a "whistle" with a frequency of 16,000 to 20,000 hz. This signal, which animals can hear 400 yards away, causes them to freeze in their tracks and is effective on all animals except cattle, sheep and camels. The signal cannot be heard by humans or pets riding in the car.
