Scottish authorities are implementing various 20mph speed limit rollouts as part of road safety and active travel initiatives. In Argyll and Bute, the design stage for proposed limits in Helensburgh and Lomond is complete under the Scottish Government’s ‘Project 20’. Meanwhile, the Ayrshire Roads Alliance is managing a phased rollout in South Ayrshire and conducting trials in East Ayrshire.

In Shetland, the Shetland Islands Council is expanding 20mph limits on several roads in Lerwick, including King Harald Street, following reports of significant speeding incidents. While the council is moving forward with these limits, it has postponed the installation of physical traffic calming measures like road humps and zebra crossings due to public opposition regarding vehicle damage, noise, pollution, and emergency response times. The council plans to evaluate the effectiveness of ‘signs only’ 20mph limits in the meantime.
