Who we are

Four Point Five was created to ensure an efficient and compliant Chain of Responsibility (CoR) related to Heavy Vehicle National Law (HVNL) within the transport industry.

Our team comprises of industry based consultants, business strategists and legal advisors with the ability and the expertise to develop a strong compliant safety culture with our business partners.

What we offer

Four Point Five offers comprehensive solutions that includes the drafting of industry and statutory compliant management plans, developed with optimal risk mitigation tools; auditing of existing management plans; consulting our clients on HVNL compliance requirements; and educating all stakeholders on HVNL awareness programs.


The Heavy Vehicle National Law (HVNL) has brought many protective measures to the freight transport business; and amongst those, the chain of responsibility (CoR) was specifically developed to raise the responsibility levels of the supply chain and make the heavy vehicle operations safer to the driver, to the companies involved, to the environment, and to general society.

Four Point Five in consultation with our clients develops HVNL and CoR management plans, tailored to suit stakeholders’ unique requirements. It is imperative to maintain a certified comprehensive HVNL and CoR management system that meets the regulatory requirements.


Your business safety and compliance systems should provide for the conduct of regular internal and external audits to ensure that the plan, the safety and compliance systems, and associated policies, procedures and practices are being implemented across all your heavy vehicle activities.

Four Point Five review and audit your existing management plans to assess and identify regulatory and safety risks. In addition, we provide third party compliance and audit certificates.


The team at Four Point Five in conjunction with our business partners assess their current HVNL and CoR risks and provide customised consultancy services. From Route optimisation, Fleet review, ISO certifications, ICAM and Full fleet Gap Analysis, we can provide you the data you need to make the best decisions for your business.


Through the application of the HVNL CoR Plan, effective supervision, the development of your employees and open communication we can assist you in the implementation of practicable solutions for the management of HVNL.

Through the risk management process of hazard identification, risk assessment and the appropriate controls, risk can be lowered to reasonable and practicable levels.

Chain of Responsibility: Roles & Liabilities

Heavy Vehicle National Law generally addresses the actions of drivers and operators; however, the breaches of these laws are often caused by other parties in the transport supply chain.

The aim of Chain of Responsibility for a heavy vehicle is to ensure everyone in the supply chain actively prevents breaches of the HVNL.

The Chain of Responsibility law also extends to preventing or reducing potential harm to yourself and others. Managing these risks ensures that you always recognise and carefully consider all potential dangers and satisfactorily reduce or avoid them before they occur.
