Australia is undergoing an unprecedented $200 billion major infrastructure build in our cities for at least a decade. And key to its success is trucks, without them none of these can be delivered. This means more trucks on our roads and increased risk of interactions between them and cyclists, pedestrians and motor bike riders. People make mistakes when on the roads and when it involves a truck it is often fatal. CLOCS-A is about reducing the impact of these mistakes such that all road uses are more aware and understanding and tolerant of each other on the road.
