The highways department is an example of a statutory service, (funded by the government). Most emergency incidents, regardless of their cause or nature, are likely to involve serious disruption to major road networks. Even if the incident is not on or near a motorway or major road, long queues of traffic, often involving hundreds of people, can occur as a result of road closures and traffic congestion near the actual scene. Traffic has to be managed effectively so that the congestion does not prolong the emergency incident, or even cause a further incident. The Highways Agency is responsible for maintaining and managing all motorway systems and ‘A’ class roads throughout England, while local authorities are responsible for other roads.
