What does K53 stand for?

It is also known as the current driver licence test as K53 is the term for the current driver's licence test. The number that is given to the test was based on the proposals that were submitted in the 1980s and then the versions which were reworked were upgraded numerically. Test number K53 was finally accepted as the approach to test the aspirant drivers. There are various types of licences that are part of HGV driving such as the Car and Trailer training, 7.5-ton lorry, etc.
