The modern Overcheck is often a necessary piece of safety equipment for certain types of harness and is an aid to the driver in keeping a horse's head properly positioned. 

An Overcheck has a practical purpose: if a horse lowers its head too far when in harness particularly if moving quickly, it can catch the bridle on the shafts of the carriage or wagon, risking an accident.
