In June I hit forty five. Because I have a Class C and D licence (rigid lorry and bus) I will have to have a full medical every five years, this also coincides with the medical for work. Sometimes I drive a large vehicle with all sorts of loads, and sometimes a coach. People expect me to see properly and be fit enough. I also will have to have the Driver Certificate of Professional Competence (CPC) which has to be renewed every five years. These are several tests that are done over five years, or in one block, to make sure I still have the skills, and not lost any, to drive large vehicles.
Compare all the above to the average car driver. Pass your test at seventeen and never have anymore training, and no medical until you reach seventy, even then it's a basic medical. As the population gets older you will have more drivers on the road whose eyesight has got worse gradually, whose driver skills are lacking and are just an accident waiting to happen. Trouble is, it could be one of us, a relative or a friend who is injured because of a basic thing like having an eye test and wearing glasses.
So, well done to South Wales Police for taking the initiative.
