[QUOTE="Ben"] Only if you know. If someone buys a bike off me, I don't ask them if they've got insurance before they ride away. It's got fuck all to do with me.[/QUOTE] I'm sure knowingly let some ride without insurance may be an offence. *Unknowingly* simply can't be an offence. Otherwise we'd all have to go round checking everyone else's documents all the time. You'd never get out of Sainsbury's car park, for a start.
