What are Traffic Regulation Orders?

Find out what a TRO is and what they are used to implement.

Traffic Regulation Orders (TROs) are legal documents that enable West Sussex County Council, as the local highway authority, to manage traffic in the county.

TROs are required to implement:

  • parking places
  • waiting, loading and unloading bays
  • speed limits
  • double yellow lines
  • one-way streets
  • turning bans
  • prohibitions of vehicles
  • vehicle weight restrictions
  • bus and cycle lanes
  • taxi ranks.

TROs can be permanent or temporary. Temporary TROs enable us to temporarily restrict or prohibit an activity on the highway, such as during a public event.

See Apply for a temporary traffic restriction for details of how to apply for short-term constraints.
