Traffic Regulation Orders

Traffic Regulation Orders (TROs) are written legal documents that we use. These allow the police, or civil enforcement officers in the case of parking restrictions, to enforce various traffic regulations. These include:

  • speed limits
  • waiting / loading restrictions
  • turning bans and one way streets
  • weight limits and prohibitions of vehicles
  • bus lanes and taxi ranks

All restrictions need a Traffic Regulation Order (TRO) which is a statutory process. On average, they last around 18 months. 

Because of the timescale we can only introduce around a dozen or so each year. 

We use a priority system to decide which schemes are most important.

How a Traffic Regulation Order (TRO) is made

A proposed Traffic Regulation Order requires a statutory procedure to be followed. This includes:

Design and consultation 

We create a proposed design for the traffic order and then consult with local councillors and parish councils, the emergency services, local public transport operators and sometimes other institutions such as The Freight Transport Association.  Changes to the proposals can be made if needed to reflect the views. 


We’ll usually display a notice at least 21 days from the start of the proposal.  You can find these in the local paper, notices on street lighting columns on the affected roads and you can also look online at our public notices.   


Objections to the proposals and comments of support must be made in writing to the address or email address on the notice during the advertising period. 

We’ll write to anyone who objects to give them the full explanation of the proposals and give them the opportunity to withdraw their objections. 

If objections are not withdrawn then an officer decision report is sent to cabinet showing the proposals and the objections and giving recommendations to be considered. When looking at the objections cabinet must decide whether to: 

  1. allow the scheme to go ahead as advertised
  2. change the scheme, or
  3. abandon it

When a decision has been made, we’ll write to anyone who has objected to let them know the decision.

Making the order

The TRO can then be formally sealed, and is advertised as a made order with a start date.   After this date our parking services may carry out enforcement as and when necessary.

Other types of orders 

Temporary Traffic Regulation Orders (TTRO)

Temporary orders may be used when works affecting the highway need short-term traffic restrictions.

A temporary TRO allows us to temporarily introduce, restrict or prohibit an activity on the highway, such as a sporting or social event. The police can close roads for public safety reasons.

Experimental Traffic Regulation Orders (ETRO)

Experimental orders are used when a scheme needs to be monitored, allowing changes to be made before restrictions are made permanent.

These orders last a maximum of 18 months.  After this they are either made permanent, changed or stopped. In the case of the first two options, an extra order will be needed.
