Motorists in the UK are expressing confusion over large black and white chequered road signs, which resemble those seen in motorsport. These signs have been spotted at various locations, including the B3084 meeting the A30 between Salisbury and Winchester, and on the B4455 near Stratford-upon-Avon. Despite their prevalence, these signs do not appear in the UK Government's 'Know Your Traffic Signs' manual or the Highway Code. Many drivers have taken to social media seeking clarification on their purpose. Users speculate that the signs are meant to provide additional warnings at junctions, particularly where visibility is a concern, such as at staggered intersections. They are often positioned near Give Way signs and are believed to enhance nighttime visibility, especially in areas known for frequent accidents. One user noted their presence along The Fosse Way, a Roman road known for its straight stretches, indicating their role as long-range hazard warnings.
