Hi I passed my driving licence in 1988, and this allowed me at that time to ride upto 125cc bikes with L-plates. Then the CBT training came in I think in 1990. My licence says Provisional entitlement A ; C+CE, Valid from XX/XX/XXXX to XX/XX/2014 D+DE, Valid from XX/XX/XXXX to XX/XX/2014 G+H The A is motorcycles over 50cc with no expiry date - subject to provisions set out in Motor Vehicle (Driving licences) Regulations, which at the time would have no doubt specified no greater than 125cc with some sort of KW (power) restriction aswell. Question: When the CBT was introduced, the regulations would have changed, but do the changes apply retrospectively to licences held before the introduction of CBT? All I found was The Motor Vehicles (Driving Licences) Regulations 1996 [URL]http://preview.tinyurl.com/3xdffor[/URL] Next Question: What do the rest of my provisionals stand for and why do 2 of them expire in 2014? Thanks
