Vehicle activated sign to help reduce speeding in Mary Tavy Parish Council 17/11/2021

Following concerns in the community about speeding, Mary Tavy Parish Council have installed a vehicle activated sign on the A386

The council wanted to address the issue of speeding vehicles on the A386, a busy road in the centre of the village. Several residents had contacted the parish council with concerns regarding vehicle speeds on the road which doesn’t have a pavement all the way along. Some parts of the A386 have a virtual footpath rather than an actual pavement and residents that needed to use the virtual footpath felt vulnerable.

A formal public meeting was held (before the Covid-19 pandemic) and was well attended. Parishioners were presented with a series of solutions to the problem including:

  • two village gateways (to raise motorist awareness that a village is being entered),
  • a community speedwatch scheme and,
  • a vehicle activated sign (VAS).

Residents largely agreed that the parish council purchase a mobile VAS. The aspect that appealed most was that a modern VAS could both display vehicle speeds as well as collecting data. The data can be fed regularly to authorities such as Devon County Council and Devon & Cornwall Police as evidence of the speeding problem in the village. 

Once an appropriate make and model of VAS had been decided by the council, they made contact with the Neighbourhood Highways Officer to outline the proposal. As part of the process, the council had to supply a map of potential locations on the A386 for placement of a mobile VAS. The process of gaining approval was very time consuming; it took almost two years to gain the necessary permission from the highways authority to erect a VAS on the A386 despite assurances from the parish council that they would purchase the VAS solely from its own funds, would conduct its own risk assessment, and be solely responsible for maintenance and insurance.

They got there in the end and received permission to erect a VAS at a couple of approved locations on the A386. It was then the clerk’s task to identify the relevant power to purchase and erect a VAS. They knew that they could use section 137(2) of the Local Government Act 1972 but that would use about a third of the council’s section 137 expenditure allowance for the financial year.

The parish council contacted DALC, requesting advice from NALC’s legal team (a free member service) on possible powers. Three possible powers that the council were considering were ruled out:

  • the power to contribute financially to traffic calming schemes (Local Government and Rating Act 1997, s.30),
  • the power to provide certain traffic signs and other notices (Road Traffic Regulation Act 1984, s.72) and,
  • the power to spend money on crime detection and prevention measures (Local Government and Rating Act 1997 s.31).

NALC ultimately advised that the council could ask the highway authority (Devon County Council) to delegate its power for the function (of installing and operating a VAS). In the end, the clerk adapted a sample document found in NALC’s ‘Local Councils Explained’ book of an agreement between a county council and a parish council which she asked the highway authority to sign to confirm that, by virtue of section 101 of the Local Government Act 1972, the parish council may exercise the function of operating a mobile vehicle activated sign at locations approved by the highway authority. 

Now the VAS is up and running perfectly and the council has signed documents to show the internal auditor with reference to the power to purchase and install a VAS without touching their section 137 expenditure allowance for the financial year.
