Im 16, but im already looking to buy a quadbike for when im 17 for road use to get me out and about. I was just wondering what the laws on this are? Such as, what protective clothing/equipment will i need? Is it legal to carry a passenger? Etc...

I have been riding quadbikes for 10 years, on and off tarmac, so i know how to handle them safely and i know they can be dangerous... But i like living life on the edge

Please give as much information as possible to help me out guys, i really appreciate it
