What is a traffic Regulation Order?
A Traffic Regulation Order (TRO) is a legal instrument that enables local authorities to regulate the movement and parking of vehicles on the public highway.
TROs are used to introduce measures such as;
- speed limits
- parking restrictions
- one‑way systems and other controls designed to manage traffic flow.
These orders play a key role in improving road safety, reducing congestion, and ensuring appropriate access for specific purposes.
