A Traffic Regulation Order (TRO) is the statutory legal document necessary to support any enforceable traffic or highway measure.
Types of traffic order
- Traffic regulation orders (TROs) These are a formal traffic regulation order that require a statutory procedure to be followed. They are required for changes to waiting and loading, one-way streets, speed limits, weight and width restrictions, access and turning restrictions and cycle/bus lanes.
- Temporary traffic regulation orders (TTROs) These may be used when works affecting the highway require short-term traffic restrictions normally to allow essential or emergency works to be carried out on the highway.
