The Traffic Management Act 2004 (c. 18) is an Act of the Parliament of the United Kingdom. It sets out how road networks should be managed by local authorities and includes regulations for roadworks. The Act has been implemented from 1 April 2008 across the United Kingdom.

This section sets out the network management duty to "secure the expeditious movement of traffic",^[3] which is defined as pedestrians as well as vehicles.

All the parties interested in occupying streets/highways need to follow the specified guidelines. The main highlights are as follows:

• Effective communication between highway authorities and parties interested in carrying out street work
• Powers given to highway authorities to impose fixed charges in case of any failure to follow the guidelines
• Disciplined approach and advance communication to plan the street works
• Introduction of web services for communication
• Introduction of Level 3 National Street Gazetteer data
• Explicit provision of cancelling/correcting or reverting the work status.

The second wave^{[weasel words]} of the Traffic Management Act 2004 aims to implement permit regulation. As part of this regulation work undertakers have to apply for a permit to work on a street.^[4] Undertaker have to discuss and agree the restriction on work timing, apparatus etc. with highway authorities. The highway authorities should approve/reject the application after verifying the permit conditions.

This allows Transport for London to designate a strategic road network in Greater London, and covers other matters.

This part covers contraventions such as vehicles parking incorrectly or using bus lanes. These are enforced by Penalty Charge Notices.^[5]
