Driver at 45 with C1 need a medical?

[kevthrev]

I have my medical for a Class C LGV licence as i am now 50. My colleague has a C1 licence (upto 7.5 tonne) and will be 45 soon. Does he need to take a medical for C1 continuation? Thanks for your help.

Thanks for the reply Grumpy. Someone without Grandfather Rights would need a medical at 45 to carry on with his C1 commercially?
