The Department of Main Roads (DMR) was established in November 1932, and undertook works across New South Wales, including maintenance of all major roads into Sydney and programs of road reconstruction, construction, upgrading and rerouting.

Within NSW, the Transport Management Centre was responsible for managing special events and unplanned incidents and disseminating information to motorists. It is the central point for identifying and directing the response to incidents such as crashes, breakdowns and spills. It passes on information to the public through the media, the RTA call centre and variable message signs along routes. In 1999 the NSW Transport Management Centre (TMC) established Traffic Commander and Traffic Emergency Patrol (TEP) services throughout the Greater Urban Area of Sydney to provide 24 hour 365 day a year coverage to "Manage the traffic arrangements around an incident scene and return the road to normal operating conditions with the utmost urgency." Traffic commanders took command of traffic management arrangements at an incident (such as a motor vehicle collision) and liaise with other response agencies such as the police, and assist in clearing the road and minimising the effects and disruption to traffic. Traffic Emergency Patrols vans patrolled major road routes and respond to unplanned incidents with the aim of returning the road to normal operating conditions as soon as possible. Both also are permitted to use and display red and blue emergency lighting and are designated as 'emergency vehicles'.
