Can 17-year-old learner drivers legally ride a quad bike on the road?

Thank you for your reply about 17-year-olds and quad bikes. I hope that you'll find the following information helpful. Although the driving licence regulations generally require a provisional licence holder on the road to be accompanied by a supervising driver, this does not apply if they are driving a vehicle in licence categories B1, B1 (limited to invalid carriages), F, G, H, or K, provided the vehicle was constructed to carry only one person. A 17-year-old driver with the B1 category on his/her provisional licence would be able to drive a single seat quadricycle on the road, provided that vehicle was suitable for road use, and it met the description of driving licence category B1 (3- or 4-wheeled vehicle with an unladen weight not exceeding 550kg).

Many thanks for the information, but this must have been asked on my behalf. It never came via me. However, since it's useful information, I'll try to run it.
