Apologies, in the UK it's merely implied... in France (where I got my license) it's more specific - they define "sufficient speed to overtake" as being 20kmph over that of the vehicle to be overtaken and the manoeuvre should be completed within 250m (10 seconds).

/yawn... HIghway Code

French Highway Code

Can't read the french one but I think those 'rules' are for overtaking that puts you in the path of oncoming traffic or other hazards hence the "check it's safe and if so - don't muck about, do it and get back into the correct lane" type of implications.
Undertaking isn't very common on roads with 1 lane in each direction except for undertaking right turning vehicles

Don't think it's intended for multi-lane highways where oppossing flows are divided with barriers which is the situation i'm referring to and where undertaking is common (granted technically illegal but common nonetheless)....i.e.motorways.

perhaps, but in the interests of avoiding road-rage, it's a good principle to try to stick to, regardless of how big the road is.

Anyhow... enough already. Let's move on to religion!

Is it legal to undertake muslims?

Are you Bison in disguise? Under-taking is inherently dangerous and illegal in every country that I know of. Have you not heard of the "blind spot"?

Rubbish - if you actually turn to check over your shoulder, which you should anyway, over or undertaking, then it's fine.
And it's def not illegal in the US on the 'freeways'.
