You should be using all lanes of traffic, and zipper merge at the end.
The main problem with zipper merges in practice are selfish people who rush to zipper and cause even more congestion because of their erratic attempt to merge. Like traffic circles they work great when everyone is doing it right and they cam get really messed up when people do it wrong.
It would be great if zipper merging was taught as part of getting a license. Or they actually required someone to learn how to zipper merge as part of their license renewal.
The other issue is people who have no spatial awareness of their vehicle and need like eight car lengths to merge over.
Done with a modicum of competence: Zipper merges are efficient and you should only merge near the end
In reality? If you see an opening, merge over sooner than later to prevent disruptions to traffic

This actually creates disruptions in traffic. Use all lanes, zipper merge at the end.
No, it fucking doesn’t because we don’t live in a perfect world and entitled/dumbasses fill the road. If I’m in the right lane and some chucklefuck is matching my speed in the on-ramp next to me and doesn’t either speed the fuck up or slow the fuck down in the 2 whole minutes they have in that lane, they’re gonna end up slamming their brakes at the end. All it would take is a modicum of awareness to get over and stop this awkward bullshit. That’s just ONE example.
This isn’t a traffic jam. This isn’t the middle of Delhi. We’re talking about normal everyday traffic. It’s 2 cars in a 4 lane highway, and the dumbass can’t even merge.
And no, it’s not my responsibility to make sure they get over. I’m not hand holding idiots.
Point is, we don’t live in a fucking vacuum and all it takes is opening your eyes and judging the situation in front of you accordingly.
God yes.
I am generally a nice-ish person. I’ll try to slow down a little to give them more room. And then they just slow down too because they don’t know how to drive without matching speed with a car next to them. And, fortunately, they aren’t looking at me so I can’t even wave them in. So it is just a waiting game of “Are they going to speed up and cut me off so that I have to slam on the brakes, or are they going to slam on the brakes at the last second and stop their lane until my lane stops to let them in?”
Nobody is saying to force your way in to the merge lane five miles ahead of the closure. If traffic is moving along, move along. But if you see an opening and know the lanes are going to merge? Merge then and there.
We’re talking about two different things then. Open road, light fast-moving traffic, lane ending - the “merge zone” lengthens with that speed and space.
Heavy slow-moving traffic, lane ending, use the lanes which are available and zipper merge at the end. Merging too soon in this situation does create congestion.
Theory: Everyone down voting you has never driven outside the US.
We don’t teach the proper way to zipper merge, so people block those doing it for cutting in line. It’s a different culture that should be changed for efficiency, just like middle lane squatting, but it’s just not important enough to address.
The United States has a strong general culture of “I got mine, fuck you.” That is certainly playing a part in this thread.
Do you mean “rush to zipper” as in “using an open lane to move forward and then zipper merge into the remaining lane when that one closes?” That is precisely what you should do.
The problem is the selfish people who refuse to let those people actually zipper merge, like OP.
@Nougat
It’s hard to discuss zipper merging because people use to justify all sorts of dick behavior. Zipping through an empty left turn only lane to skip to the head of a right turn only lane for example. That’s not an example of zipper merging but there’s tons of people who I’ve seen argue that’s acceptable behavior.That’s not an example of zipper merging but there’s tons of people who I’ve seen argue that’s acceptable behavior.
We agree that that’s not what we’re talking about, and those people are wrong. That wasn’t hard at all.
I mean speeding at a far higher speed than the other plane and then suddenly slamming on the brakes and forcing themselves into the other lane. Rushing to merge, not just zipper merging at a similar speed.
If the lane being used is still open for forward traffic, that is a completely legitimate zipper merge, although it would be safer to match speed more gradually and, of course, wait for an appropriate space to merge into. As a hypothetical, that’s a borderline case, and it’s certainly possible to adjust the details of the hypothetical to make the merging driver into the dick. But I’m not sure that’s a useful pursuit.
How is matching speeds to merge and finding a space an edge case? That is how merging works.
Not matching speeds is how people going slower than the flow of traffic when merging from on ramps causes issues. Matching speeds when merging is crucial.
Zipper merging requires matching speed with the lane you are merging into so that drivers can make gradual changes in speed to make an opening for the person merging. That avoids sending a wave of brake slams that results from sudden unexpected lane changes. If you’re passing a bunch of people, you’re probably not doing a zipper merge.
You’re also much less likely to end up with someone not letting you over if they see you matching speed instead of speeding up to the merge point.
If you’re passing a bunch of people, you are using the open lane to travel. By the time the lane you are in comes to an end, you then modulate your speed to match traffic in the slower lane, and merge. Because cars have brakes.
You need to start matching speed at the start of the signage for the merge. At that point it’s no longer just a lane, it is a lane with restrictions.
You’re not actually increasing total throughput by speeding ahead, you’re only changing the order. The total throughput is determined by the flow of traffic after the constriction point. That flow is smoothest when drivers match speed.
No, the problem is the people who incorrectly merge early, making “rushing” possible.
Zipper merge is effective if it takes place at the end of the line, not the merge point. Essentially as traffic backs up, the merge point should back up as well. That isn’t practical in reality; you can’t dynamically move the merge point IRL.
OP you fucking idiot, if you expect people to get over two miles back then you’ve artificially extended the lane closure an additional two miles.
You’re an asshole. It’s a zipper merge.
I think it is similar to when lanes merge. Better to stay in lane and then do zipper method.
If lane is open, cars will speed up until they reach merged/closed lane…
What do y’all say?
Not you Picard… say it ain’t so!!
It’s a zipper merge if the lane closes. Use all available lanes and alternate the right of way to keep traffic moving. It’s assholes who think they’re high and mighty that cause headaches in these situations
People are SUPPOSED to use both lanes for as long as safety possible, and then zipper-merge.
It’s called a zipper merge, you muppet. They’re doing what they’re supposed to for more efficient traffic flow. You’re just being an ass.
People like OP are a chronic problem in the UK.
Yes, I know that “we queue” in the UK. So why not make a number of queues equal to the number of available lanes and then take it in turns when it’s time to merge? Instead of making a single queue multiple lengths longer than it needs to be that will inevitably block even more junctions further back and cause even more traffic, YOU FUCKING MORON!!!
Edit: downvoted by nine absolute mongs that obviously weren’t taught very well in their driving lessons. Not brave enough to put forward a counter argument, are you though?
