Scottish Trunk Roads are major routes that connect key cities and regions across Scotland. They are essential for transportation, facilitating the movement of goods and people. These roads are managed by Transport Scotland and are designed to handle higher traffic volumes compared to local roads. Trunk Roads are typically numbered with an "A" prefix, such as A9 or A82. They often feature dual carriageways and are strategically important for tourism, commerce, and emergency services. Maintenance and upgrades are regularly conducted to ensure safety and efficiency for all road users.
