Classic cars that become tax exempt when they reach 40-years-old will no longer automatically be allowed to display retro black and silver number plates.
The new rule, which came into force from January 1, means only models built before January 1, 1980 can continue to use the classic plate designs.
The traditional black and silver number plates were used on all cars before yellow rear and white front plates were introduced in 1973.
In 2015, the DVLA said vehicles manufactured 40 years ago would be allowed to display the black and silver plates but this now no longer the case.
A DVLA spokesman told Express.co.uk owners of models built before January 1 1981 would still be able to apply for tax exemptions.
The spokesman said: “From January 1, 2021, the display of registration marks regulations will be updated to break the link with the historic tax class exemption.
“While vehicles manufactured before January 1, 1981, will be able to apply for the historic tax class from April 1, 2021, only vehicles manufactured before January 1, 1980 will be eligible to display black number plates with silver or white characters.”
