A Scottish trunk road is a major road in Scotland that is part of the national road network. These roads are maintained by the Scottish Government and are designed to facilitate long-distance travel and transport. They connect cities, towns, and important destinations, ensuring efficient movement of people and goods across the country. Trunk roads are typically wider and have higher speed limits than local roads. They often feature dual carriageways and are crucial for economic activities. Examples of trunk roads include the A9, which runs from Dunblane to Inverness, and the A82, connecting Glasgow to Inverness.
