ROG:
I was wrongly under the impression that the change from the HGV system to the present LGV system was 1997 - I learned something new today - thanks
There were two directives, the second in 1997 refered to the two part testing ie C before CE, photocard licences and other changes with entitlements. The first directive was 1/6/90 (not 1991 as I originally thought) and replaced the separate HGV/ PCV licence. (source FTA yearbook)
