So I bought a second hand bike, my first bike ever.

I've got a little blue book called the 行驶证
A big green book called a 机动车登记证书
A piece of paper proving my insurance 保险
I still haven't got the 检验
And I need to convert my 驾照 to a chinese one too.

What must you carry on you when riding? Do I need to carry all of this stuff? I've been told I need to show the 行驶证 to buy petrol. But I filled it up with petrol fine without showing it. The pump attendant couldn't stop laughing at the laowai with a motorbike

After I get my 驾照 I need to ride the bike 15km to a garage where they can do the 检验. What is the legality of riding without the 检验 if you're riding to where you can get it?
