it's completely legal to filter?

However, by the same token, bikers filtering need to keep their eyes open in situations where others may manoeuvre in a position where the biker might not see them immediately.

I don't know what that means [/quote]

Sorry, I probably could have been clearer there.

Imagine, for instance, you're filtering past traffic and you go past a lorry and a bus and then suddenly there's a car coming across in front of you because you'd not seen that there was a side turning on the left and the bus had stopped to let the car out.

If you'd noticed that there was a gap forming in front of the bus you should think "hang on, why isn't the bus moving on? Let's just slow down a minute and take things slowly..."
