Filtering magic or idiocy?

[Maimboy]

I have a filtering question. Most mornings I have to endure joining a heavily congested dual-carriageway, from an equally congested slip road. Filtering up the outside I often have to stop or trickle along at 3mph, looking for a gap while avoiding running into the vehicle ahead. It's deeply annoying.

However, I recently witnessed a knight of the road (a scooter rider) make the following manoeuvre (which I have illustrated for you at great expense), and now I use it every day; no stopping, no dawdling, I just zip into the traffic flow ahead of the other vehicles fighting for position.

Question is: is it foolish and/or illegal?

'Tis the sort of thing I do on a daily basis.

In my opinion, any gap is good to go, if the bike I'm riding will fit through the gap, and I can make progress (by that I mean get to the front of a queue), I do it. Pavements aren't out of the question either.

You may undertake traffic waiting to turn right, but not at any other time.

I'd do it. And they are waiting to turn right, on to the dual carriageway

Considering it makes it so much easier to do compared to the alternative that you suggested, then it has to be illegal. Anything that makes a difficult situation like that easy to overcome has to be. !

As for the "only undertake when turning right":

If I'm interpreting it correctly, then I'd do that also.

I think you'd be safer on the left of most vehicles that are looking very hard for a gap on their right.

Would a copper nick you? I don't know.

Would you win the court case if it all went tits up? I don't know.

There is a similar junction near to me, it's a popular entry slip road that joins a dual carriageway very close to a busy roundabout. It's popular because a few dickheads come off, then back on to bypass any queue's forming at the roundabout.

On the bike, I would only ever approach that junction in lane 2 of the dual carriageway, or do as you would if approaching from the slip.

In the 4X4, any cunt that either forced their way in, or purposely blocked me from entering, I would drag them from their cars & repeatedly stab them in the neck.

Jet-pack?, Helicopter? Flashing blue lights?, your own personal tank? they will all help you get to the front of the queue

Your biggest risk in making that maneuver is if several vehicles all push into the queue together but one towards the back is a bit late getting in then a long gap can form in front of him, and as he squeezes over if the vehicle behind him decides to dodge around him to jump a few places using the newly-opened gap. If you happen to be cruising up the inside at the moment he decides to make a lunge you're gonna get squished into the barrier or planted into his rear quarter.

As far as I know, when it comes to speed limits as above:

Single-carriageway NSL: 60mph.
Dual-carriageway NSL: 70mph.

This means that single carriageway roads (any amount of lanes, no central reservation) is 60mph limit under NSL.

Dual carriageway roads (any amount of lanes, split by a central reservation) is a 70mph limit under NSL.

This is all for a standard car/motorcycle as obviously the limit is variable for towing vehicles/HGVs.

As cars are moving right off the slip road onto the main carriageway, I'd argue its SAFER to be on the left, as they may see a gap and pull into it crossing solid white lines and hatched boxes to do so.

As for undertaking... its slow moving traffic, so you could argue that its allowable.

I've been told that in and of itself, undertaking is not an offence, but it can be seen as driving without due care and attention or even dangerous driving, and it'd be one of these offences you'd be called up on.

[multijoy]

I filter on the left all the time. I don't enjoy it, though, and it's only in static traffic - if I can get on the outside, I'll do that.

The traffic doesn't expect to see anyone on the left, but at least in your case the lane's are a bit wider than some shitty london a-road, and you've got the shoulder to dive into, and there's little or no reason for anyone to turn left across you (not that that is any reason for them not to!)

In that specific instance I'd probably do that, but in first at about 25/30 so I'm making lots of noise. if theres two lines of traffic on a slip (like the m61/m60 junction) I tend to go down the middle then skip into the left lane.

If there's a gap use it.

I'd do that. In fact, if i knew what was coming up, I'd probably be on the left all the way down.
