Carter Bar was the location of Truce days, that were held between the Lord Wardens of the Marches of both countries to dispense cross border justice in the Late Middle Ages and Early modern period. Truce days were also held at Carlisle and Berwick upon Tweed.
Carter Bar forms a popular point for tourists to stop and take photographs on the Anglo-Scottish border. There are two marker stones on either side of the A68 for this purpose, the original stone created by local Borders stonemason, Edy Laub. Upper Redesdale, the Scottish Borders (including Tweeddale) and to the east, the Cheviot hills are all visible from Carter Bar. However, its altitude means snow is possible even in late spring and early autumn, and the Carter Bar pass can be subject to frequent snow-related closures during the winter.
