About TROs and ETROs
Traffic Regulation Orders
Traffic regulation orders (TROs) are the legal mechanism used to introduce permanent changes to a road’s layout and how traffic uses it. For example, a TRO would be used to introduce double yellow lines that restrict parking on a street.
The legal power to promote TROs comes from the Road Traffic Regulation Act 1984. We follow the process set out in The Local Authorities Traffic Orders (Procedure) (Scotland) Regulations 1999 for how we consult on and advertise our TROs.
Early in the process of introducing a TRO, we consult with statutory bodies, such as the emergency services. Following this, we advertise the TRO to the public for a minimum of 21 days. During that time, anyone can raise objections to the TRO. Any objections will then be considered by us and where appropriate, by councillors who sit on the Council’s Transport and Environment Committee.
In some specific cases, the objections will also be considered by an independent external party. All objections are considered before the decision to make the TRO is finalised and the changes to the road introduced.
Experimental Traffic Regulation Orders
An Experimental Traffic Regulation Order (ETRO) is like a Traffic Regulation Order – it’s also a legal mechanism to introducing changes to how traffic uses a street and the road layout. We can use ETROs to trial schemes on our streets, to understand how they work in practice. This allows us to make a more informed decision as to whether to make the changes permanent. To make a trial (experimental) change permanent, we would have to follow the TRO process.
Changes made under an ETRO can stay in place for up to 18 months.
The process for introducing an ETRO is very similar to a permanent TRO, with the same consultation and advertising process. Objections will be considered by the Council and, where appropriate, Transport and Environment Committee before the ETRO is finalised and changes to the road are introduced.
