If you currently own a car in the UK manufactured after 1960, you are required to complete an annual road worthiness test.
Starting in May 2018, vehicles 40 years and older will be exempt from the mandatory road testing. The ruling matches the 40 year rolling exemption for classic cars from annual excise taxes. And compared to the EU's 30 year cut off, it covers a greater variety of older cars.
This is fantastic news for UK classic car owners and importers because it makes owning a classic car that much cheaper.
