20mph speed limit trials get underway

Perth & Kinross Council has begun formally testing lower speed limits in five locations around the Council area from Wednesday 4 March 2020.

Over the years, the Council has received many requests from Councillors, Community Councils and local residents for the introduction of 20mph speed limits. Sites for reduced speed limits have previously been identified through an existing strategy introduced in 2016.

Approval was given by the Environment & Infrastructure Committee in 2019 for a 20mph Speed Limit Trial in five locations:

  • Aberfeldy
  • Dalginross
  • Errol
  • Kinnesswood
  • Rattray

Environment and Infrastructure Convener, Councillor Angus Forbes said: "Each of the trial sites has a particular characteristic that may impact on how effective a 20mph speed limit can be - they include a village, school site, town, residential core and a village with an A class road. Comparing these characteristics will allow us to determine the suitability of future 20mph limits in an effective and clear way."  

The trial period will run for nine months, and will involve the use of different measures to assess what affects motorists' compliance with the 20mph speed limit, along with traffic counts, as follows:



February 2020 (completed)

Traffic counts undertaken to assess pre-trial vehicle speeds

January 2021

Submit a report to the Environment and Infrastructure Committee on trial findings and recommendations.

During each phase of the trial, traffic counts will be undertaken for a two-week period which will provide data on traffic volumes and vehicle speeds. The data gathered will enable an assessment of how each measure has affected travel patterns. The report to Committee will cover the trial period, its overall impact and recommendations for how the existing 20mph Speed Limit Strategy will be revised or developed in the future.
