None of the motorcycle underrun protection devices accepted for use in Victoria have been tested on the end terminal of road safety barriers. As a result, they must terminate before the end terminal. This can result in strange and somewhat unintuitive applications (see photo 1 on the left). 

As a temporary measure until a tested system is put to market, Victoria has allowed the use of a product called PolyBuffer that does not attach to the end terminal. PolyBuffer sits in-front of the system and is expected not to affect the function of the end terminal during a strike by a passenger vehicle.
