Vehicle registration plates of Lesotho

Lesotho requires its residents to register their motor vehicles and display vehicle registration plates.
Plates are blue-on-white for private vehicles and red-on-white for government vehicles. They follow the format of one or two letters followed by four numbers. Diplomatic Plates are blue-on-white however have the letters CD on them.
A "mokorotlo", the same colour as the characters on the plate, is stuck onto the plate to show a 5-year validity period.
Dealer plates are also red-on-white but do not follow the A 1234 standard and do not show the "mokorotlo".
Before 1979, private plates were white-on-black and had an additional preceding 'L' which stood for Lesotho.
