Tougher tests for heavy vehicle brakes from today


New brake tests for heavy vehicles (over 3.5 tonne gvm) such as trucks, buses and motor caravans begin today as part of a drive to reduce crashes and improve the safety of heavy vehicles.

The new testing procedures are being introduced as part of the implementation plan of the Heavy-vehicle Brakes Rule. While the rule formally came into force in March 2007, a phased implementation plan was developed in consultation with industry in order to allow for the necessary changes to be made at Certificate of Fitness (CoF) testing stations.

The phased rollout of the tests will begins today in most of the lower North Island. 

The new procedures require heavy vehicles to be brake tested on a Roller Brake Machine (RBM) in a ‘semi-laden’ condition or by simulated load where the vehicle is pulled down using ‘tie down’ straps attached to the chassis or axles. Previously heavy vehicles were not required to be tested while carrying a load (or with a simulated load), and most were presented for Certificate of Fitness inspections unladen. 

NZ Transport Agency’s Driver and Vehicle Certification Unit Manager Alex Sims says the new tests will help to address one of the most important vehicle safety issues for New Zealand road users by ensuring that heavy vehicles are able to brake properly under all conditions.
