To think I had every right to be in the right hand lane when driving the speed limit on a dual carriage way

You should have been on the left. You were both wrong; both of you were hazards for different reasons. I often drive in the right hand lane on the motorway but I will always move over if I am going at a similar speed to the left or middle lane, and even if I’m not, I’ll move over if someone comes behind me who is faster. You can’t control other drivers I’m afraid!

Is anyone saying that? No, they're saying the OP shouldn't lane hog. If the other driver was here too, they'd be told not to speed.

I had similar happen to me yesterday, except I was indicating to turn right off the dual carriageway. It was absolutely ridiculous. The speed and closeness he was to me was terrifying. Thank goodness the filter lane was clear as I pulled into at full speed. Usually other drivers see you are indicating to turn right and move over to the left to allow you to slow.

OP - Never post on AIBU about a driving incident. It will always be your fault no matter what. The fact that every action the other driver took was illegal is irrelevant, the fact that if you admit to doing 31 in a 30 you are a monster, but here you are completely wrong to criticise his speeding.

Sometimes it is not safe to be chopping and changing lanes, especially when you have a need to be in the right hand lane, the fact he had time to undertake is irrelevant, he was probably incredibly unsafe when doing so and no doubt caused others to have to brake.

He was a twat.

Obviously we should stick to the speed limit, @P3kingDuck - I don’t think anyone is arguing the opposite - but the only driving standards you can control are YOUR driving standards.

Hence, you should have followed the Highway Code and returned to the left hand lane after overtaking, and stayed there until you needed to move into the right hand lane when the dual carriageway split. It wasn’t your job to try to stop the other driver speeding.

When someone is caught speeding on here people call them everything and say of course no one should speed but on this thread posters are saying people should speed, how very odd

I did a speed awareness course recently and they covered this. You are correct to not speed, I was quite shocked at the impact being even a couple of miles over the limit could have on stoppage times and injury to anyone who gets hit by you.
But you can't control other people - the safest thing to do in that situation is pull over. Otherwise you are stressed and tense, and the other driver is probably wound up and on an aggressive power trip. Neither are safe for driving. Our instructor told us to just let them overtake and move on with your day. If you can't move over, he suggested extending your travel distance with the car ahead to give you more space in case he hits or shunts you from behind.

I do understand where you are coming from OP. Aggressive, speeding drivers make the roads more dangerous for everyone and it's tempting to try and curtail their shitty behaviour.

But it doesn't work. They don't give a shit, and attempting to teach them a lesson by blocking them just leads to two distracted drivers and an even more dangerous situation overall. You should have calmly moved over and not returned to the right hand lane until necessary.

Depends if the left lane was free and traffic light you should be in the left lane and change lanes when necessary for your right turn off. . If it’s busy and you feel you won’t be able to get over then it’s reasonable to stay in the right lane on approach to your turn off on the right (for example if both lanes are congested with slow moving traffic in each lane).

You have to adapt to the driving conditions at the time.

I don’t antagonise bumper huggers anymore if I can avoid them or appease them I do. So many false claims and violence on the road now.

You should have been in the left hand lane. And you know it.

You should be in the left lane unless overtaking

Obviously speeding car should have also been in the left lane too and not speeding.

If you're doing the speed limit and you aren't far from where you need to be in it then I think it's fine. If it was miles away then probably better to be in the left lane.

Whether the other driver was or wasn't adhering to the speed limit isnt relevant.

1. Had you been instructed by signs to move to the right lane for the flyover?

1. Were you actively overtaking?

If the answer to both of the above is no, you were in the wrong. It's that simple.

It depends how close you were to the split in the road so it's hard to judge if you should've been in that lane or not. However, you may actually have been going under the speed limit depending on how accurate your car is. When the needle is on 50 in mine, I'm only doing 43-44. So he could've been doing 40-45 whilst stuck behind you which would be annoying although doesn't give him the right to drive aggressively.

Your actions were passive aggressive and wrong.
You should have been driving in the left lane (speed limit or not) until the point of turning off, or until you needed to overtake someone yourself.

.The right-hand lane is for overtaking

And yet I see just as many right hand lane hoggers as middle lane ones. Often the inner lane is the clearest on the moterway.

If the right hand line had either overhead or on the road signage indicating the need to be in that lane to utilise the flyover then you were in the right. If you hadn't yet reached the signage, then you were in the wrong. You have avoided answering their question.
The speed is irrelevant

"So we don't need to adhere to the speed limit"

You literally completed a speed awareness course not that long ago.. So which one are you, so against speeding you won't move lanes or got caught speeding so now you want to control the speed everyone else can drive?

Agree with the consensus. You should stay in the left hand lane until you NEED to be in the right hand lane.

If someone else chooses to speed, that's up to them.

You were both in the wrong. You for being in the wrong lane and not adhering to the highway code, and them for speeding.

Old duffers in flat caps resolutely in the middle lane with no car in sight in the left hand lane springs to mind. Other annoying drivers are also available, but this is the type I keep encountering.

Pig headed drivers like you actually cause accidents

in my experience it’s the ones who speed and/or are on their phones.

Speeding is never acceptable

How far from the flyover were you?

Irrespective of anyone’s speed you should stay on the left unless overtaking or in a lane where the road forks.

The other driver was an arsehole, no doubt about it, but unless the fork was close you were in the wrong, and he was speeding.

Speeding is acceptable for whatever reason but you should stay left until you turn off unless the left lane was jammed.
