The Cayman Islands requires its residents to register their motor vehicles and display vehicle registration plates.^[1] Vehicles plates usually have six numbers on them, separated into groups of three. Most plates have 'Cayman Islands' written beneath the numbers and are North American standard 6 × 12 inches (152 × 300 mm).^[2]

In 2003, quincentennial plates (known as Q-plates) were issued; they had four blue numbers following a 'Q' on a background depicting a picturesque Cayman scene with celebratory logos. Initially, Q-plates were issued with white characters, but these were recalled and replaced.
