What age do you have to ride a 250cc quad on the road in England?

You can ride a Quadbike on the UK roads once you have passed your driving test - as long as the vehicle is designed for the road that is. So based on this - 17 is the earliest you can drive a car so 17 would be the key. If you are looking for a Quad Bike - Or to insure one there is a new site in the UK called www.myquadbike.com and they are complete specialists for this market. The site only went live this week so be prepared as it may look a little sparse. Given a couple of weeks then you will see it filling up with plenty of machines.
