TROs may be permanent, temporary or experimental, and each one is used for different things.
Permanent traffic regulation orders remain in force until they’re updated or cancelled. Generally, they fall into one of four categories:
- Community TROs. These are usually used to address local issues, such as introducing new speed limits or double yellow lines and tend to be relatively simple and non-contentious.
- Developer TROs. New developments, such as houses or blocks of flats, usually need TROs to manage how new or existing roads are used to comply with planning restrictions. For example, a TRO could be needed to create an access road to new buildings.
- Highway schemes. These tend to be more complex schemes that need to be delivered under council programmes, such as new speed bumps or protected cycle lanes.
- Resident Parking Zones. These comprehensive TROs are needed to manage parking across a wider area.
Temporary traffic regulation orders (TTROs) are used for changes to roads that are only needed for a limited time, such as during road works or events. They could be used to temporarily close roads, introduce parking or waiting restrictions, or change the speed limit for vehicles.
TTROs don’t have a consultation, as they enable construction or utility works, or to allow special events to be held. These usually mean it’s necessary to close or partially close roads or footpaths while the works or event takes place. TTROs can last for a maximum of eighteen months.
Experimental traffic regulation orders (ETROs) are used when changes to roads need to be monitored to check if they’re working successfully or meeting the aims of a project. This could include new speed bumps, cycle lanes or parking restrictions, for example. ETROs can remain in place for a maximum of eighteen months while the changes are monitored and assessed.
Once a TRO is applied for, the proposed changes must go through a process before works can begin.
