How?
Managing a DfW policy can only be effectively handled if it is integrated into your arrangements for managing health and safety at work. You should look at your health and safety systems and consider whether they adequately cover this area of work. The main areas you need to address are policy, responsibility, organisation, systems and monitoring.

Overall Policy Statement A Driving for Work Policy should be implemented if you employ more than five employees.
Risk Assessment A risk assessment is nothing more than a careful examination of what 'at work' activities can cause harm to people.
Minimising Risk Through Control Measures You can control the risk, to reduce the possibility of harm to your employees, by applying basic control measures.
Rules and Procedures Implement rules and procedures for your employees to aid in eliminating the hazards.
Data Recording Employers of five or more employees are required to record the significant findings of their risk assessment.
Audit, Communication and Review You will need to monitor and review your assessment to ensure that the risks to those who drive for work, and others, are suitably controlled.
