In practice road transport administration involves at least two ministries, the ministry of transport and the ministry responsible for policing. Often it involves more. Local government also usually plays an important role in implementing road transport policy. Achieving effective communication between these agencies is not easy. In developing countries there is often a shortage of trained personnel able to fulfil the demands of government administration, and severe financial constraints apply, which limit possible options for tackling the problems. Consequently institutional constraints are often crucial in determining development of road transport regulation.
